A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Toro.com for a list of all approved attachments and accessories.
To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.
Note: Determine the left and right sides of the machine from the normal operating position.
Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Toro.
Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects. These can be thrown or interfere with the operation of the machine and may cause personal injury to the operator or bystanders.
Wear appropriate personal protective equipment such as safety glasses, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing and loose jewelry which may get tangled in moving parts.
This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
Wear hearing protection when operating this machine.
Check that the operator presence controls, safety switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly.
Do not operate the mower when people, especially children, or pets are in the area. Stop the machine and attachment(s) if anyone enters the area.
Do not operate the machine without the entire grass collection system, discharge deflector, or other safety devices in place and in proper working condition. Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.
Use extreme care when handling fuel.
In certain conditions gasoline is extremely flammable and vapors are explosive.
A fire or explosion from gasoline can burn you, others, and cause property damage.
Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any gasoline that spills.
Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.
Do Not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.
Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.
Store gasoline in an approved container and keep it out of the reach of children.
Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.
If fuel is spilled, Do Not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.
Do Not operate without entire exhaust system in place and in proper working condition.
In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage.
Always place gasoline containers on the ground away from your vehicle before filling.
Do Not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.
If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do Not use a nozzle lock open device.
Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank/container opening.
Keep away from eyes and skin.
Never siphon by mouth.
Fuel tank vent is located inside the roll bar tube. Removing or modifying the roll bar could result in fuel leakage and violate emissions regulations.
Do Not remove roll bar.
Do Not weld, drill, or modify roll bar in any way.
To help prevent fires:
Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.
Clean up oil and fuel spills and remove fuel soaked debris.
Allow the machine to cool before storing the machine in any enclosure. Do Not store near flame or any enclosed area where open pilot lights or heat appliances are present.
For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.
Do not use gasoline containing methanol.
Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.
Do not add oil to gasoline.
Use a fuel stabilizer/conditioner in the machine to provide the following benefits:
Keeps fuel fresh longer when used as directed by the fuel-stabilizer manufacturer
Cleans the engine while it runs
Eliminates gum-like varnish buildup in the fuel system, which causes hard starting
Important: Do not use fuel additives containing methanol or ethanol.
Add the correct amount of fuel stabilizer/conditioner to the fuel.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
Park the machine on a level surface.
Engage the parking brake.
Shut off the engine and remove the key.
Clean around the fuel-tank cap.
Fill the fuel tank to the bottom of the filler neck (Figure 7).
Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand.
Before starting the machine each day, perform the Each Use/Daily procedures listed in .
New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.
To avoid injury or death from rollover, keep the roll bar in the fully raised, locked position and use the seat belt.
Ensure that the seat is secured to the machine.
There is no rollover protection when the roll bar is in the down position.
Lower the roll bar only when absolutely necessary.
Do not wear the seat belt when the roll bar is in the down position.
Drive slowly and carefully.
Raise the roll bar as soon as clearance permits.
Check carefully for overhead clearances (i.e., branches, doorways, electrical wires) before driving under any objects and do not contact them.
Important: Always use the seat belt with the roll bar in the raised position.
Raise the roll bar to the operating position and rotate the knobs until they move partially into the grooves (Figure 8).
Raise the roll bar to the full upright position while pushing on the upper roll bar so that the pins snap into position when the holes align with the pins (Figure 8).
Push on the roll bar and ensure that both pins are engaged.
If the safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury.
Do not tamper with the interlock switches.
Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.
The safety-interlock system is designed to prevent the engine from starting unless the following occurs:
The parking brake is engaged.
The blade-control switch (PTO) is disengaged.
The motion-control levers are in the NEUTRAL-LOCK position.
The safety-interlock system also is designed to shut off the engine when the motion-control levers are moved from the NEUTRAL-LOCK position with the parking brake engaged or if you rise from the seat when the PTO is engaged.
The hour meter has indicators to notify the user when the interlock component is in the correct position. When the component is in the correct position, an indicator displays on the screen.

The slots for the rear-shock assemblies have detent positions for reference. You can position the rear-shock assemblies anywhere in the slot, not just in the detent positions. The following graphic shows the position for a soft or firm ride and the different detent positions (Figure 14).
Note: Ensure that the left and right rear-shock assemblies are always adjusted to the same positions.
Adjust the rear-shock assemblies (Figure 15).
The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur.
Operating engine parts, especially the muffler, become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire.
Allow engine parts, especially the muffler, to cool before touching.
Remove accumulated debris from muffler and engine area.
Engine exhaust contains carbon monoxide, which is an odorless deadly poison that can kill you.
Do Not run engine indoors or in a small confined area where dangerous carbon monoxide fumes can collect.
The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.
This mower was designed for one operator only. Do not carry passengers and keep all others away from machine during operation.
Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
Operate only in daylight or good artificial light.
Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, Do Not operate the machine; seek shelter.
Use extra care while operating with accessories or attachments, such as grass collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights if required.
Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause the operator to lose their balance or footing.
Be sure all drives are in neutral and parking brake is engaged before starting engine. Use seat belts with the roll bar in the raised and locked position.
Start the engine carefully according to instructions with feet well away from the blades.
Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition.
Keep clear of the discharge opening at all times. Never mow with the discharge door raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly.
Keep hands and feet away from moving parts. If possible, Do Not make adjustments with the engine running.
Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.
Do Not operate the machine without guards, shields, and safety devices in place and working properly.
Keep hands, feet, hair, jewelry, or clothing away from rotating parts.
Never raise the deck with blades running.
Be aware of the mower discharge path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.
Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. Do Not mow in reverse unless absolutely necessary.
Do Not change the engine governor setting or overspeed the engine.
Park the machine on level ground. Stop engine, wait for all moving parts to stop, and remove the spark plug wire(s).
Before checking, cleaning or working on the mower.
After striking a foreign object or abnormal vibration occurs (inspect the mower for damage and make repairs before restarting and operating the mower).
Before clearing blockages.
Whenever you leave the mower. Do Not leave a running machine unattended.
Stop engine, wait for all moving parts to stop:
Before refueling.
Before dumping the grass catcher.
Before making height adjustments.
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.
Keep children out of the mowing area and under the watchful care of another responsible adult, not the operator.
Be alert and turn the machine off if children enter the area.
Before and while backing or changing direction, look behind, down, and side-to-side for small children.
Never allow children to operate the machine.
Do Not carry children, even with the blades shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.
Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, the operator must:
Review and understand the slope instructions in the manual and on the machine.
Use an angle indicator to determine the approximate slope angle of the area.
Never operate on slopes greater than 15 degrees.
Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.
Identify hazards at the base of the slope. Do Not operate the machine near drop offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand trimmer to mow the grass in these areas.
Avoid starting, stopping or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.
Do Not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.
Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
Use extra care while operating with accessories or attachments, such as grass collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights.
If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.
A Rollover Protection System (roll bar) is installed on the machine.
There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.
Do Not remove the ROPS.
Keep the roll bar in the raised and locked position and use seat belt.
Lower the roll bar only when absolutely necessary.
Do Not wear seat belt when the roll bar is down.
Drive slowly and carefully.
Raise the roll bar as soon as clearance permits.
Be certain that the seat belt can be released quickly in the event of an emergency.
Check carefully for overhead clearances (i.e. branches, doorways, and electrical wires) before driving under any objects and Do Not contact them.
In the event of a rollover, take the unit to an Authorized Service Dealer to have the ROPS inspected.
Replace a damaged ROPS. Do Not repair or revise.
Any accessories, alterations, or attachments added to the ROPS must be approved by Toro.
Use the mower deck as a step to get into the operator’s position (Figure 17).
Always engage the parking brake when you stop the machine or leave it unattended.
Park the machine on a level surface.
The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
Note: Engaging the blade-control switch (PTO) with the throttle position at half or less causes excessive wear to the drive belts.
You can move the throttle control between FAST and SLOW positions (Figure 22).
Always use the FAST position when engaging the PTO.
Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor.
Note: You may need multiple attempts to start the engine the first time after adding fuel to an empty fuel system.
Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always remove the key and engage the parking brake when leaving the machine unattended.
Important: Make sure that the fuel-shutoff valve is closed before transporting or storing the machine, as fuel leakage may occur. Engage the parking brake before transporting. Make sure that you remove the key as the fuel pump may run and cause the battery to lose charge.
The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves.
The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.
The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine.
Use caution when making turns.
Slow the machine down before making sharp turns.
Note: The engine shuts off when you move the traction-control with the parking brake engaged.
To stop the machine, pull the motion-control levers to the NEUTRAL position.
Disengage the parking brake; refer to Disengaging the Parking Brake.
Move the levers to the center, unlocked position.
To go forward, slowly push the motion-control levers forward (Figure 26).
Move the levers to the center, unlocked position.
To go backward, slowly pull the motion-control levers rearward (Figure 27).
The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
Without a grass deflector, discharge cover, or a complete grass-catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.
Never remove the grass deflector from the mower deck because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
Never put your hands or feet under the mower deck.
Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the key switch to the OFF position, and remove the key from the key switch.
Make sure that the grass deflector is in the down position.
The transport lock has 2 positions, and is used with the deck-lift pedal. There is a LOCK position and an UNLOCK position for the transport position of the mower deck (Figure 28).
The height-of-cut is adjusted from 25 to 140 mm (1 to 5-1/2 inches) in 6 mm (1/4 inch) increments by relocating the clevis pin into different hole locations.
Move the transport lock to the lock position.
Push on the deck-lift pedal with your foot, and raise the mower deck to the transport position (also the 140 mm (5-1/2 inch) cutting height position) as shown in Figure 29.
To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 29).
Select a hole in the height-of-cut bracket corresponding to the height-of-cut desired, and insert the pin (Figure 29).
Push on the deck lift, pull back on the transport lock, and slowly lower the mower deck.
Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers.
Whenever you change the height of cut, it is recommended to adjust the height of the anti-scalp rollers.
Mount the skids in the lower position when operating in height of cuts higher than 64 mm (2-1/2 inches) and in the higher position when operating in height of cuts lower than 64 mm (2-1/2 inches).
Note: When the skids become worn, switch the skid to the opposite sides of the mower, flipping them over. This allows you to use the skids longer before replacing them.
Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Remove the carriage bolts and nuts from each skid (Figure 35).
Move each skid to the desired position and secure them with the carriage bolts and nuts.
Note: Only use the top or center sets of holes to adjust the skids. The bottom holes are used when switching sides on the mower deck, at which time they become the top holes on the other side of the mower.
To prevent damaging the skid, torque the carriage bolts and nuts for each skid to 12.4 to 14.7 N∙m (110 to 130 in-lb).
This procedure applies only to machines with the flow baffle knob. Certain models have nuts and bolts instead of the flow baffle knob that you can adjust the same way.
You can adjust the mower discharge flow for different types of mowing conditions. Position the knob and baffle to give the best quality of cut.
Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Loosen the knob.
Slide the knob to the desired position.
Tighten the knob.
The following figures are recommendations only. Adjustments vary by grass type, moisture content, and the height of the grass.
Note: If the engine power draws down and the mower ground speed is the same, open the baffle.
This is the fully-rear position. The suggested use for this position is as follows:
Short, light grass mowing conditions
Dry conditions
Smaller grass clippings
Propels grass clippings farther away from the mower
Use this position when bagging. Always align it with the blower opening.
This is the fully-forward position. The suggested use for this position is as follows:
Tall, dense grass mowing conditions
Wet conditions
Lowers the engine-power consumption
Allows increased ground speed in heavy conditions
For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
Cut grass slightly longer than normal to ensure that the cutting height of the mower deck does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.
It is best to cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
To improve cut quality, use a slower ground speed in certain conditions.
When mowing uneven turf, raise the cutting height to avoid scalping the turf.
If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward.
Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the mower blades after each use for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
Park machine on level ground, disengage drives, set parking brake, stop engine, remove key or disconnect spark plug wire. Wait for all movement to stop and allow the machine to cool before adjusting, cleaning, repairing, or storing. Never allow untrained personnel to service machine.

Loosen both brake-mounting bolts 1/2 to 1 full turn as shown in Figure 78.
Note: Do not remove the brake pole from the field shell/armature. The brake pole has worn to match the armature and needs to continue to match after you remove the shim to ensure proper brake torque.
Using needle-nose pliers, or by hand, hold the tab and remove the shim (Figure 79).
Note: Do not discard the shim until the clutch is functioning properly.
Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.
Torque each bolt (M6 x 1) to 12.3 to 13.7 N∙m (9.5 to 10.5 ft-lb).
Using a 0.25 mm (0.01 inch) thick feeler gauge, verify that a gap is present between the rotor and the armature face on both sides of the brake pole as shown in Figure 80 and Figure 81.
Note: Due to the way the rotor and the armature faces wear (peaks and valleys) it is sometimes difficult to measure the gap accurately.
If the gap is less than 0.25 mm (0.01 inch), then install the shim.
If the gap is sufficient, proceed to the safety check in step 6.
Perform the following safety check:
Sit on the seat and start the engine.
Make sure that the blades do not engage with the blade-control switch (PTO) in the OFF position, and that the clutch is disengaged.

Inspect the cutting edges (Figure 102).
If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades.
Inspect the blades, especially in the curved area.
If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 102).
Note: The machine must be on a level surface for the following procedure.
Raise the mower deck to the highest height-of-cut position.
While wearing thickly padded gloves, or other adequate hand protection, slowly rotate the blade into a position that allows you to measure the distance between the cutting edge and the level surface the machine is on (Figure 103).
Measure from the tip of the blade to the flat surface (Figure 104).
Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 105).
Measure from the tip of the blade to the flat surface (Figure 106).
Note: The variance should be no more than 3 mm (1/8 inch).
If the difference between A and B is greater than 3 mm (1/8 inch), replace the blade with a new blade; refer to Removing the Blades and Installing the Blades.
Note: If a bent blade is replaced with a new blade, and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Service Dealer for service.
If the variance is within constraints, move to the next blade.
Repeat this procedure on each blade.
Replace the blades if they hit a solid object, or if the blade is out of balance or bent.
Place a wrench on the flat of the spindle shaft or hold the blade end using a rag or thickly padded glove.
Remove the blade bolt, bushing, and blade from the spindle shaft (Figure 107).
Use a file to sharpen the cutting edge at both ends of the blade (Figure 108).
Note: Maintain the original angle.
Note: The blade retains its balance if the same amount of material is removed from both cutting edges.
Check the balance of the blade by putting it on a blade balancer (Figure 109).
Note: If the blade stays in a horizontal position, the blade is balanced and can be used.
Note: If the blade is not balanced, file some metal off the end of the sail area only (Figure 108).
Repeat this procedure until the blade is balanced.
Install the bushing through the blade with the bushing flange on the bottom (grass) side of the blade (Figure 110).
Install the bushing/blade assembly into the spindle shaft (Figure 111).
Apply copper-based lubricant or grease to the threads of the blade bolt as needed to prevent seizing. Install the blade bolt finger-tight.
Place a wrench on the flat of the spindle shaft and torque the blade bolt to 75 to 81 N∙m (55 to 60 ft-lb).
Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Check the tire pressure in the drive tires; refer to Checking the Tire Pressure.
Position the transport lock in the latching position.
Push the deck-lift pedal all the way forward and the deck latches at the 14 cm (5-1/2 inches) transport position (Figure 112).
Insert the height-adjustment pin into the 7.6 cm (3 inches) cutting-height location.
Release the transport lock and allow the deck to lower to the cutting height.
Raise the discharge chute.
On both sides of the deck, measure from the level surface to the front tip of the blade (Postion A) as shown in Figure 113.
Note: The measurement should read 7.6 mm (3 inches)
Fine-tune the adjustment nut on the front deck-lift assembly by turning it (Figure 114).
Note: To increase the height, turn the adjustment nut clockwise; to decrease the height, turn the nut counterclockwise.
Note: If the front deck links do not have enough adjustment to achieve accurate cut height, you can use the single-point adjustment to gain more adjustment.
To adjust the single-point system, loosen the 2 bolts at the bottom of the height-of-cut plate (Figure 115).
Note: For rear-discharge machines, the mower deck is attached in the back holes at the factory. Refer to Figure 116. If needed, use the front holes for further adjustment when leveling the mower deck.
If the deck is too low, tighten the single-point-adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single-point-adjustment bolt by rotating it counterclockwise (Figure 117).
Note: Loosen or tighten the single-point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This regains some up and down adjustment on each of the 4 deck links.
Tighten the 2 bolts at the bottom of the height-of-cut plate (Figure 115).
Note: In most conditions, the back blade tip should be adjusted 6.4 mm (1/4 inch) higher than the front.
Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).
On both sides of the deck, measure from the level surface to the back tip of the blade (postion B) as shown in Figure 113.
Note: The measurement should read 8.3 cm (3-1/4 inches)
Fine tune the screw adjuster by turning it to get 8.3 mm (3-1/4 inches) height (Figure 114).
To increase the height, turn the adjustment nut clockwise; to decrease, turn counterclockwise.
Measure until all 4 sides are the correct height.
Tighten all of the nuts on the deck-lift-arm assemblies.
Lower the discharge chute.
Lock out the spring-loaded deck arms before servicing or removing the mower deck.
Deck-lift arm assemblies have stored energy. Removing the deck with out releasing the stored energy can cause serious injury or death.
Do not attempt to disassemble the deck from the front frame without locking out the stored energy.
Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Place the height adjustment pin in the 7.6 cm (3 inch) cutting-height location.
Note: This locks the deck-lift arms in the lowest position when the deck is removed and the stored energy in the deck spring is released.
Remove the belt covers.
Lift up the floor pan and insert a ratchet into the square hole in the deck idler (Figure 118 or Figure 119).
Rotate the deck idler clockwise, lift up on the belt-guide tab (rear-discharge machines only), and remove the mower belt (Figure 118 or Figure 119).
Remove and retain the hardware on both sides of the deck as shown in Figure 120.
Raise the deck struts and secure them in the raised position.
Slide the deck out to the right side of the machine.
An uncovered discharge opening could allow the machine to throw objects toward you or bystanders, resulting in serious injury. Also, contact with the blade could occur.
Never operate the machine unless you install a mulch plate, discharge deflector, or grass collection system.
Remove the locknut, bolt, spring, and spacer holding the deflector to the pivot brackets (Figure 121).
Remove the damaged or worn grass deflector (Figure 121).
