This blade was designed to provide excellent lift and dispersion in almost any condition. If more or less lift and discharge velocity is required, consider a different blade.
Attributes: Excellent lift and dispersion in most conditions
The blade generally performs best in lower heights of cut—1.9 to 6.4 cm (3/4 to 2-1/2 inches).
Attributes:
Discharge remains more even at lower heights of cut.
Discharge has less tendency to throw left and thus a cleaner look around bunkers and fairways.
Lower power requirement at lower heights and dense turf.
The blade generally performs better in the higher heights of cut—7 to 10 cm (2 to 4 inches).
Attributes:
More lift and higher discharge velocity
Sparse or limp turf is picked up significantly at higher heights of cut
Wet or sticky clippings are discharged more efficiently reducing congestion in the cutting unit.
Requires more horsepower to run
Tends to discharge further left and can tend to windrow at lower heights of cut
Using a high-lift blade with the mulching baffle could cause the blade to break, resulting in personal injury or death.
Do not use the high-lift blade with the mulching baffle.
This blade was designed to provide excellent leaf mulching.

Contact your Toro distributor if the stopping distance of the machine is not within 0.6 m (2 ft) of this distance.
Transport Reverse Speed
If the maximum transport speed set by the supervisor is above 8.0 km/h (5.0 mph), the maximum reverse speed is 8.0 km/h (5.0 mph).
If the maximum transport speed set by the supervisor is at or below 8.0 km/h (5.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.
Mowing Reverse Speed
If the maximum mow speed set by the supervisor is above 6.4 km/h (4.0 mph), the maximum reverse speed is 6.4 km/h (4.0 mph).
If the maximum mow speed set by the supervisor is at or below 6.4 km/h (4.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.
This machine displays estimated traction speeds in kilometers per hour (km/h) or miles per hour (mph).
The instantaneous speed is displayed in the upper left-hand corner of the cruise control and virtual pedal stop screens.
The traction speeds are estimated, and calibrated to be most accurate at 8.0 km/h (5.0 mph) while mowing. Displayed speeds are accurate when it is 0.8 km/h (0.5 mph) above or below the display speed while driving on dry, flat pavement.
Contact your authorized Toro distributor if the machine's observed speeds deviate more than 2.4 km/h (1.5 mph) from the displayed speeds.
When starting the machine in cold weather, warm-up mode limits the engine speed to low idle for a short period after the engine is started, preventing potential component damage from operating the machine with cold oil.
A snowflake icon on the InfoCenter screen denotes when warm-up
mode is active. Do not operate the machine until after the warm-up
period.
The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.
Do not carry passengers on the machine and keep bystanders and children out of the operating area.
Operate the machine only in good visibility to avoid holes or hidden hazards.
Avoid mowing on wet grass. Reduced traction could cause the machine to slide.
Keep your hands and feet away from rotating parts. Keep clear of the discharge opening.
Look behind and down before backing up to be sure of a clear path.
Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
Stop the blades whenever you are not mowing.
Stop the machine, remove the key, and wait for all moving parts to stop before inspecting the attachment after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.
Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.
Disengage the drive to the cutting unit, shut off the engine, remove the key, and wait for all movement to stop before adjusting the height of cut (unless you can adjust it from the operating position).
Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.
Never leave a running machine unattended.
Before you leave the operator’s position, do the following:
Park the machine on a level surface.
Disengage the power takeoff and lower the attachments.
Engage the parking brake.
Shut off the engine and remove the key.
Wait for all movement to stop.
Operate the machine only in good visibility. Do not operate the machine when there is the risk of lightning.
Do not use the machine as a towing vehicle.
Use accessories, attachments, and replacement parts approved by Toro only.
Use the cruise control (if equipped) only when you can operate the machine in an open, flat area that is free from obstacles and where the machine can move at a constant speed without interruption.
The ROPS is an integral and effective safety device.
Do not remove any of the ROPS components from the machine.
Ensure that the seat belt is attached to the machine.
Pull the belt strap over your lap and connect the belt to the buckle on the other side of the seat.

Replace damaged ROPS components. Do not repair or alter them.
A cab installed by Toro is a roll bar.
Always wear your seat belt.
Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.
Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.
Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.
Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.
Do not operate a machine under any conditions where traction, steering, or stability is in question.
Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.
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.
Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.
Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.
If possible, keep the cutting unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.
Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.
This machine has an automotive-style throttle that is controlled by the traction pedal.
This machine does not have a separate throttle switch or throttle lever.
When you remove your foot from the traction pedal, the machine dynamically brakes to a stop.
The pedal controls are optimized to provide a reactive yet stable response, allowing you to maintain consistent control over rough terrain, while still allowing for quick, smooth braking.
While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.
When mowing, the engine speed will automatically raise to high idle.
If the engine is at low idle, performing a function like lifting the cutting units or pressing the traction pedal raises the engine speed to a minimum working speed, providing enough power to efficiently perform the function.
Limit the machine idle time as recommended for diesel particulate filter (DPF) regeneration. Shut of the machine to prevent extended idling time.
The maximum speeds set in the PIN protected menu settings are set by the supervisor to limit the machine’s maximum traction speed.
The achievable traction pedal use, cruise control, and pedal stop traction speeds are all limited by the maximum speeds set in the PIN protected menu.
If an obstacle is in the way, lift the cutting units or mow around it.
When transporting the machine between work areas, shut off the PTO, and raise the cutting units to the fully upward position. This allows the traction pedal to operate like a car.
Always drive slowly in rough areas.
Never shut off the machine while driving the machine.
To get familiar with the features of the machine, practice operating the machine.
Lift the cutting units, disengage the parking brake, press the forward traction pedal, and carefully drive to an open area.
Practice driving the machine, because it has a hydrostatic transmission and its features can differ from other turf-maintenance machines.
Practice moving forward and reverse, and starting and stopping the machine. To stop the machine, remove your foot from the traction pedal and let it return to NEUTRAL.
Note: When going downhill in the machine, you may need to use the reverse pedal to stop.
Remove your foot from the traction pedal to stop quickly.
Practice driving around obstacles with the cutting units up and down. Be careful when driving between narrow objects so that you do not damage the machine or cutting units.
The traction pedal controls the forward and reverse speed of the machine and the dynamic braking when you return it to neutral.
This machine is equipped with an automotive-style throttle—the engine speed and the machine speed respond to the pedal movement.
While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.
While mowing, the engine automatically raises to high idle to optimize mowing performance, and the traction pedal only controls traction speed.
The further you push the pedal forward or reverse, the faster the machine moves.
To control the machine to a smooth stop while transporting or mowing, use your foot to return the traction pedal to neutral at your desired rate.
To engage maximum braking, remove your foot from the traction pedal, allowing it to return to neutral. The machine dynamically brakes to a stop.
This traction system allows you to customize the acceleration settings for operator comfort and course conditions. Refer to Understanding the Acceleration Mode for changing the settings.
The virtual pedal stop (VPS) feature allows you to temporarily set a maximum traction speed that is less than the password-protected supervisor maximum traction speed.
To temporarily set the maximum speed of the machine, press the traction pedal fully forward (Figure 28). You can set a separate speed for the mow range and transport range (Figure 29).
To access this feature, press the up or down navigation button from the main screen. (Figure 29).
Note: This feature reverts back to the supervisor maximum speed settings when you turn the key to the OFF position.
This feature allows you to customize the speed settings for your comfort level, or to customize the speed settings to fit the application.
Whenever you change the maximum traction speed using the supervisor maximum speed settings or Virtual Pedal Stop, the traction pedal is automatically reprogrammed to use the full pedal stroke between neutral and the new maximum speed. This means that you gain more precise control of the traction speed at lower maximum speed settings.
Set the maximum speed temporarily lower for mowing the cleanup pass on the fairway.
Set the maximum speed temporarily lower for improved control operating in or near the maintenance shop.
Set the maximum speed temporarily lower for improved control loading the machine onto a trailer.
The cruise-control switch locks in the cruise control to maintain the desired ground speed. Pressing the rear of the switch turns the cruise control off, the middle position of the switch enables the cruise-control function, and the front of the switch sets the desired ground speed.
After the cruise control switch is enabled and the speed is set (Figure 30), use the InfoCenter to adjust the speed setting of the cruise control (Figure 30 and Figure 31).
To disengage the cruise control, use the following:
When in transport range, press the reverse traction pedal, engage the parking brake, or press the cruise control switch to the OFF position.
When in mow range, press the reverse traction pedal, engage the parking brake, disengage the PTO, or press the cruise control switch to the OFF position.
Note: Disengaging the cruise control results in the machine dynamically braking to a stop. If you want to disengage cruise control while driving, press the traction pedal for a smooth transition from cruise control to manual speed control.
Set a cruising speed for long distances without many obstacles.
On rough terrain, use the InfoCenter to control the speed.
Use the cruise control for turnarounds as follows:
While mowing, set a safe, comfortable speed for turning around at the end of mowing passes.
Press the traction pedal to increase the speed for mowing during the mowing pass.
Take your foot off the pedal when turning around for the next mowing pass.
The machine will slow down to the low cruise control setting, allowing you to make an efficient turnaround at a constant speed.
After turning around, use the traction pedal to increase the machine speed for the next mowing pass.
This feature determines how quickly the machine changes traction speed when the traction pedal is not in the NEUTRAL position.
Note: If you take your foot off the traction pedal, allowing it to return to the NEUTRAL position while the machine is moving, the braking profile is engaged. The braking profile is always the same and cannot be customized by the acceleration mode feature.
Enter the protected menus in the InfoCenter to change the acceleration mode. The acceleration mode has the following 3 positions:
Low—least aggressive acceleration and deceleration
Medium (default)—medium acceleration and deceleration
High—most aggressive acceleration and deceleration
The counterbalance system maintains hydraulic back pressure on the cutting-unit lift cylinders. The counterbalance system monitors the real-time traction pressure, dynamically changing the lift-cylinder back pressure to optimize traction capability and after-cut appearance. The counterbalance pressure has been set at the factory to an optimal balance of after-cut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting unit but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may reduce the quality of the after-cut appearance; refer to Changing the Counterbalance Settings.
The customizable counterbalance setting controls are as follows:
Low—the most amount of weight on cutting units and the lowest weight on the drive wheels
Medium—medium weight on cutting units and the drive wheels
High—the least amount of weight on cutting units and the highest weight on machine drive wheels
You can change the amount of required cutting-unit counterbalance (upward lift) to meet your current mowing conditions.
Park the machine on a level surface, lower the cutting decks, turn the key in the switch to the OFF position, and engage the parking brake.
Turn the key in the switch to the RUN position.
In the InfoCenter Settings Menu, scroll down to Counterbalance.
Press the right button to select counterbalance and change between the low, medium, and high settings.
Note: After completing the adjustment, move the machine to a test area and operate the machine with the new setting. The new counterbalanced setting may change the effective height of cut.
With Smart Power, the operator does not have to listen to the engine speed in heavy load conditions. Smart Power prevents the engine from bogging down in heavy cutting conditions by automatically controlling the machine speed and optimizing cutting performance.
Note: By default, the Smart Power feature is ON.
Important: The fuel system automatically bleeds itself before starting the engine if you are starting the engine for the first time, the engine has shut off due to lack of fuel, or you have performed maintenance on the fuel system.

The diesel-particulate filter (DPF) removes soot from the engine exhaust.
The DPF regeneration process uses heat from the engine exhaust that is increased by the catalyst to reduce accumulated soot into ash.
To keep the DPF clean, remember the following:
Run the engine at full engine speed when possible to promote DPF self-cleaning.
Use the correct engine oil.
Minimize the amount of time that you idle the engine.
Use only ultra low sulfur diesel fuel.
Operate and maintain your machine with the function of the DPF in mind. Engine under load generally produces adequate exhaust temperature for DPF regeneration.
Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the DPF.
The exhaust temperature is hot (approximately 600°C (1,112°F) during DPF regeneration. Hot exhaust gas can harm you or other people.
Do not operate the engine in an enclosed area.
Ensure that there are no flammable materials around the exhaust system.
Ensure that the hot exhaust gas does not contact surfaces that may be damaged by heat.
Do not touch a hot exhaust system component.
Do not stand near or around the exhaust pipe of the machine.

Change mowing patterns often to minimize a poor after-cut appearance from repeatedly mowing in the same direction. This is the most effective way to prevent washboarding.
Refer to the After-cut Appearance Troubleshooting Guide available at www.Toro.com.
To achieve the professional straight-line cut and striping that is desirable for some applications, find a tree or other object in the distance and drive straight toward it.
Bolt-in mulching baffles are available for the cutting units. The mulching baffles perform well when you maintain turf on a regular schedule to avoid removing more than 25 mm (1 inch) of growth per cutting. When you cut too much growth with the mulching baffles installed, the after-cut appearance may deteriorate and the observed power to cut the turf increases. The mulching baffles also perform well for shredding leaves in the fall.
Remove no more than approximately 25 mm (1 inch), or 1/3 of the grass blade when cutting. In exceptionally lush and dense grass, you may need to raise your height-of-cut setting.
A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges, which impairs growth and increases susceptibility to diseases. Ensure that the blade is in good condition and that there is a full sail; refer to Inspecting and Sharpening the Blade.
Ensure that the cutting chambers are in good condition. Straighten any bends in the chamber components to ensure correct blade tip/chamber clearance. Ensure all rollers and pivoting joints do not have play in them to prevent turf damage or poor after cut appearance.
After mowing, thoroughly wash the machine with a garden hose with no nozzle to avoid contamination and damage to the seals and bearings caused by excessive water pressure. Ensure that the radiator and oil cooler are kept free of dirt or grass clippings. After cleaning, inspect the machine for possible hydraulic-fluid leaks, damage, or wear to the hydraulic and mechanical components, and check the cutting-unit blades for sharpness.
Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.
To help prevent fires, ensure that the cutting units, drives, mufflers, cooling screens, and engine compartment are free from grass and debris buildup. Clean up oil or fuel spills.
If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended.
Allow the engine to cool before storing the machine in any enclosure.
Remove the key and shut off the fuel (if equipped) before storing or hauling the machine.
Never store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.
Maintain and clean the seat belt(s) as necessary
Remove the key and shut off the fuel (if equipped) before storing or transporting the machine.
Use care when loading or unloading the machine into a trailer or a truck.
Use full-width ramps for loading the machine into a trailer or a truck.
Tie the machine down securely.
In an emergency, you can move the machine forward by actuating the bypass valve in the variable-displacement hydraulic pump and pushing or towing the machine.
Important: Do not push or tow the machine faster than 3 to 4.8 km/h (2 to 3 mph). If you push or tow at a faster speed, internal transmission damage may occur.The bypass valves must be open and the brake released whenever you push or tow the machine.
Unlatch the seat base and tilt the seat open.
Locate the bypass valve under the seat and on the top of the hydrostat (Figure 37).
Loosen the valves with 3 turns to allow the oil to bypass internally.
Note: Because the fluid is bypassed, the machine can be moved slowly without damaging the transmission.
Locate the brake release manifold near the front right tire and behind the hydraulic tank (Figure 38).
Insert the long end of a ratchet or similar object, hold the black knob in on the manifold, and pump the manifold 3 times. As soon as there is substantial resistance when pumping the brake is released.
Important: Do not pump the manifold after it does not pump easily. Damage could occur if the manifold is pumped too much.
Note: Once the pressure is built up in the manifold, the brake will be released for approximately 60 minutes. If needed after 60 minutes, release the brake again by pumping the manifold.
Push or tow the machine.
Set the brake by pulling the black knob out or starting the engine.
Note: The brake automatically resets when you start the engine and you do not need to pull the black knob out.
Close the bypass valves. Torque the valves to 11 N∙m (5 to 8 ft-lb).
Important: Ensure that the bypass valves are closed before you start operating the machine. Running the engine with an open bypass valve causes the transmission to overheat.
Note: Determine the left and right sides of the machine from the normal operating position.
Before you leave the operator’s position, do the following:
Park the machine on a level surface.
Disengage the power takeoff and lower the attachments.
Engage the parking brake.
Shut off the engine and remove the key.
Wait for all movement to stop.
Wear appropriate clothing, including eye-protection; long pants and substantial, slip-resistant footwear. Keep hands, feet, clothing, jewelry, and long hair away from moving parts.
If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance.
Allow machine components to cool before performing maintenance.
If the cutting units are in the transport position, use the positive mechanical lock (if equipped) before you leave the machine unattended.
If possible, do not perform maintenance while the engine is running. Keep away from moving parts.
Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.
Support the machine with jack stands whenever you work under the machine.
Carefully release pressure from components with stored energy.
Keep all parts of the machine in good working condition and all hardware tightened, especially blade-attachment hardware.
Replace all worn or damaged decals.

The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.
Important: Check the engine oil daily. If the engine-oil level is above the Full mark on the dipstick, the engine oil may be diluted with fuel;If the engine oil level is above the Full mark, change the engine oil.
The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill the engine with oil.
Important: Keep the engine oil level between the upper and lower limits on the dipstick; the engine may fail if you run it with too much or too little oil.
Park the machine on a level surface.
Check the engine-oil level (Figure 50).
Note: When using different oil, drain all old oil from the crankcase before adding new oil.

This Operator’s Manual contains more detailed fuel and fuel system maintenance information than the Yanmar® engine Owner’s Manual, which is a general-purpose reference relating to fuel and fuel maintenance.
Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality require your attention to avoid downtime and extensive engine repairs.
The fuel system has extremely tight tolerances due to the emissions and control requirements. Diesel fuel quality and cleanliness is more important for the longevity of today’s high-pressure common rail (HPCR) fuel-injection system used on diesel engines.
Important: Water or air in the fuel system will damage your engine! Do not assume that new fuel is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and use your fuel supply within 180 days.
Important: If you do not follow the procedures for fuel filter replacement, fuel system maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform all fuel system maintenance at the specified intervals or whenever the fuel is contaminated or its quality is poor.
Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks is often overlooked and leads to the contamination of fuel delivered to the machine.
Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days. This helps eliminate water and other contaminates in the fuel.
If you do not remove the water from the storage tank or machine fuel tank, it can lead to rust or contamination in the storage tank and fuel system components. Tank sludge developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel injectors.
Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality in the tank.
Ensure that your fuel comes from a quality supplier.
If you find water or contaminants in your storage tank or machine fuel tank, work with your fuel provider to correct the problem and perform all fuel system maintenance.
Do not store diesel fuel in tanks or canisters made with zinc-plated components.

Remove the roller-mounting bolt (Figure 73).
Insert a punch through the end of the roller housing and drive the opposite bearing out by alternating taps to the opposite side of inner bearing race. There should be a 1.5 mm (0.060 inch) lip of inner race exposed.
Push the second bearing out in press.
Inspect the roller housing, bearings, and bearing spacer for damage (Figure 73). Replace any damaged components and assemble them.
Press the first bearing into the roller housing (Figure 73). Press on the outer race only or equally on the inner and outer race.
Insert the spacer (Figure 73).
Press the second bearing into the roller housing (Figure 73). Pressing equally on the inner and outer race until the inner race contacts the spacer.
Install the roller assembly into the cutting-unit frame.
Verify that there is no more than a 1.5 mm (0.060 inch) gap between roller assembly and the roller mount brackets of the cutting-unit frame. If there is a gap over 1.5 mm (0.060 inch), install enough 5/8-inch diameter washers to take up the slop.
Important: Securing the roller assembly with a gap larger than 1.5 mm (0.060 inch) creates a side load on the bearing and can lead to premature bearing failure
Torque the mounting bolt to 108 N∙m (80 ft-lb).
Inspect the blade periodically for wear or damage.
Use care when checking the blades. Wrap the blades or wear gloves, and use caution when servicing the blades. Only replace or sharpen the blades; never straighten or weld them.
On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.
The rotary deck comes from the factory preset at 5 cm (2 inches) height of cut and blade rake of 7.9 mm (0.310 inch). The left and right heights are also preset to within ± 0.7 mm (0.030 inch) of the other.
The cutting deck is designed to withstand blade impacts without deformation of the chamber. If a solid object is struck, inspect the blade for damage and the blade plane for accuracy.
Remove the hydraulic motor from the cutting deck and remove the cutting deck from the tractor.
Use a hoist (or minimum of 2 people) and place the cutting deck on a flat table.
Mark 1 end of the blade with a paint pen or marker. Use this end of the blade to check all heights.
Position the cutting edge of the marked end of the blade at 12 o’clock (straight ahead in the direction of mowing) (Figure 74) and measure height from table to cutting edge of blade.
Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 74) and measure the heights.
Compare the 12 o’clock measured height to the height-of-cut setting. It should be within 0.7 mm (0.030 inch). The 3 and 9 o’clock heights should be 1.6 to 6.0 mm (0.06 to 0.24 inch) higher than the 12 o’clock setting and within 1.6 to 6.0 mm (0.06 to 0.24 inch) of each other.
Note: If any of these measurements are not within specification, proceed to Adjusting the Blade Plane.
Start with the front adjustment (change 1 bracket at a time).
Remove the height-of-cut bracket (front, left, or right) from the deck frame (Figure 75).
Adjust 1.5 mm (0.060 inch) shims and/or 0.7 mm (0.030 inch) shim between the deck frame and bracket to achieve the desired height setting (Figure 75).
Install the height-of-cut bracket to the deck frame with the remaining shims assembled below the height-of-cut bracket.
Secure the socket-head bolt/spacer and flange nut.
Note: Socket-head bolt/spacer are held together with thread-locking adhesive to prevent the spacer from falling inside the deck frame.
Verify the 12 o’clock height and adjust if needed.
Determine if only 1 or both (right and left) height-of-cut brackets need to be adjusted. If the 3 or 9 o’clock side is 1.6 to 6.0 mm (0.06 to 0.24 inch) higher than the new front height then no adjustment is needed for that side. Adjust the other side to within 1.6 to 6.0 mm (0.06 to 0.24 inch) of the correct side.
Adjust the right and/or left height-of-cut brackets by repeating steps 1 through 3.
Secure the carriage bolts and flange nuts.
Again, verify the 12, 3, and 9 o’clock heights.
Replace the blade if it hits a solid object, is out of balance, or is bent. Always use genuine Toro replacement blades to ensure safety and optimum performance.
Park the machine on a level surface, raise the cutting unit to the transport position, engage the parking brake, shut off the engine, and remove the key.
Note: Block or lock the cutting unit to prevent it from accidentally falling.
Grasp the end of the blade using a rag or thickly-padded glove.
Remove the blade bolt, anti-scalp cup, and blade from the spindle shaft (Figure 76).
Install the blade, anti-scalp cup, and blade bolt and tighten the blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).
Important: The curved part of the blade must be pointing toward the inside of the cutting unit to ensure proper cutting.
Note: 7After striking a foreign object, torque all spindle-pulley nuts to 115 to 149 N∙m (85 to 110 ft-lb).
Raise the cutting deck to the transport position, turn the key in the ignition switch to the OFF position, and engage the parking brake.
Block the cutting deck to prevent it from falling accidentally.
Examine the cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Figure 77).
Note: Since sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine.
If wear is noticed (Figure 77), replace the blade; refer to Inspecting the Blade Plane.
If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 77). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or bystanders.
Inspect the blade periodically for wear or damage.
Always replace a worn or damaged blade.
Inspect the cutting edges of all blades. Sharpen the cutting edges if they are dull or nicked. Sharpen only the top of the cutting edge and maintain the original cutting angle to make sure that it is sharp (Figure 78).
If dull or nicked, sharpen only the top cutting edge while maintaining the original cutting angle (Figure 78).
Note: The blade will remain balanced if the same amount of metal is removed from both cutting edges.
To check the blade for being straight and parallel, lay the blade on a level surface and check its ends.
Note: Position the ends of the blade slightly lower than the center, and the cutting edge lower than the heel of the blade. This blade produces a good quality of cut and requires minimal power from the engine. By contrast a blade that is higher at the ends than the center, or if cutting edge is higher than the heel, the blade is bent or warped and must be replaced.
Install the blade, sail facing toward cutting deck, with the anti-scalp cup and blade bolt. Torque the blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).
Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.
