Note: Determine the left and right sides of the machine from the normal operating position.
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 a fuel stabilizer is used.
Do not add oil to gasoline.
In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.
Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.
Never fill the fuel tank inside an enclosed trailer.
Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.
Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.
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 that can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
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 fuel-dispenser nozzle.
If you must use a fuel-dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or conditioner bottle opening.
Avoid contact with skin; wash off spills with soap and water.
Use a fuel stabilizer/conditioner in the machine to provide the following benefits:
Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.
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 gasoline stabilizer/conditioner to the gasoline.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline.
Note: 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 the gasoline to expand.
Park the machine on level ground.
Shut the engine off and set the parking brake.
Clean around the fuel tank cap.
Fill the fuel tank to the bottom of the filler neck. Ensure there is empty space in the tank to allow the gasoline to expand (Figure 7).
Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.
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 rear part of the seat is secured with the seat latch.

Rotate the release valve levers horizontally to run the machine (Figure 32).
Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.
Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving-vehicle emblem is dangerous and can lead to accidents, causing personal injury.
Do not drive the machine on a public street or roadway.
If you are using a trailer, connect it to the towing vehicle and connect the safety chains.
If applicable, connect the trailer brakes.
Load the machine onto the trailer or truck.
Shut off the engine, remove the key, set the brake, and close the fuel valve.
Use the tie-down loops on the machine to securely fasten it to the trailer or truck with straps, chains, cable, or ropes (Figure 33).
Use extreme caution when loading or unloading the machine onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back the machine up the ramp and drive it forward down the ramp (Figure 34).
Important: Do not use narrow individual ramps for each side of the machine.
Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 35). On flat ground, this requires a ramp to be at least 4 times as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the machine moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If you are loading the machine on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle.
Loading a machine onto a trailer or truck increases the possibility of a tip-over and could cause serious injury or death.
Use extreme caution when operating a machine on a ramp.
Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the ROPS will clear the top of an enclosed trailer.
Use only a full-width ramp; do not use individual ramps for each side of the machine.
Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.
Ensure the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This will ensure that ramp angle does not exceed 15 degrees on flat ground.
Back the machine up the ramps and drive it forward down the ramps.
Avoid sudden acceleration or deceleration while driving the machine on a ramp as this could cause a loss of control or a tip-over.
For best mowing and maximum air circulation, operate the engine at the FAST throttle 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 in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.
Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height you have used in the past is generally the best 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. 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.
If the cutting width of the mower is wider than the mower that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.
If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.
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.
Clean clippings and dirt from the underside of the mower after each use. If grass and dirt buildup inside the mower, the cutting quality eventually becomes 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 cutter blades daily 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.

Note: Proper inflation pressure for tires is 90 kPa (13 psi).
Position the transport lock in the latching position.
Push the deck lift pedal all the way forward and the deck will latch at the 14 cm (5-1/2 inches) transport position (Figure 90).
Insert the height-adjustment pin into the 76 mm (3 inch) height-of-cut location.
Release the transport lock and allow the deck to lower to the cutting height.
On both sides of the deck, measure from the level surface to the front tip of the blade (position A) as shown in Figure 91.
Note: The measurement should read 7.6 mm (3 inches).
If needed, loosen the whizlock nut on the side of the yoke and the jam nut on top. Fine-tune the screw adjuster by turning it to get 7.6 cm (3 inches) height (see Figure 92).
Note: To increase the height, turn the adjuster screw clockwise; to decrease the height, turn it counterclockwise.
Note: If the front deck links do not have enough adjustment to achieve accurate cut height, you can utilize 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 94).
Note: The mower deck is attached in the back holes at the factory. Refer to Figure 93. 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 95).
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 94).
Note: For most conditions, adjust the black blade tip 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 (position B). Ensure the measurement is 8.3 cm (3-1/4 inches) (Figure 91).
Fine-tune the screw adjuster by turning it to get 8.3 mm (3-1/4 inches) height (Figure 92).
To increase the height, turn the adjustment nut clockwise; to decrease, turn counterclockwise.
Measure until all 4 sides are the correct height. Tighten all the nuts on the deck lift arm assemblies.
To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand.
A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death.
Inspect the blade periodically for wear or damage.
Replace a worn or damaged blade.
Park the machine on a level surface, disengage the blade-control switch (PTO), and set the parking brake.
Turn the ignition key to the OFF position, remove the key, and disconnect the spark-plug wires from the spark plugs.

Inspect the cutting edges (Figure 96).
If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades.
Inspect the blades, especially the curved area.
If you notice any damage, wear, or a slot forming in this area, immediately install a new blade (Figure 96).
Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and set the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Rotate the blades until the ends face forward and backward (Figure 97).
Measure from a level surface to the cutting edge, position A, of the blades (Figure 97).
Rotate the opposite ends of the blades forward.
Measure from a level surface to the cutting edge of the blades at the same position as in step 4.
Note: The difference between the dimensions obtained in steps 4 and 5 must not exceed 3 mm (1/8 inch).
Note: If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced.
A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.
Always replace bent or damaged blade with a new blade.
Never file or create sharp notches in the edges or surfaces of blade.
Replace a blade if it hits an object, if the blade is out of balance, or if the blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in nonconformance with safety standards.
Hold the blade end using a rag or a thickly padded glove.
Remove the left and center blade bolt, curved washer, and blade from the spindle shaft (Figure 98).
Remove the right blade bolt (left-hand threaded bolt), curved washer, and blade from the spindle shaft (Figure 99).
Note: Make note of the type blade and where each blade is installed. See Figure 99 for the correct position.
Use a file to sharpen the cutting edge at both ends of the blade (Figure 100).
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 101).
Note: If the blade stays in a horizontal position, the blade is balanced and ready to use.
If the blade is not balanced, file some metal off the end of the sail area only (Figure 102).
Repeat this procedure until the blade is balanced.
Important: The right blade on this mower deck is counter-rotating and uses a left-hand threaded blade bolt. Use Figure 103 for the correct placement of the mower blades.
Install the left and center blades, curved washers, and blade bolts to the spindle shafts (Figure 102 and Figure 103).
Note: Ensure the curved part of the blade is pointing upward toward the inside of the mower deck to ensure proper cutting.
Note: Ensure the curved-washer cone is installed toward the bolt head (Figure 102).
Install the right blade, curved washer, and blade bolt (left-hand threaded bolt) to the spindle shaft (Figure 102 and Figure 103).
Torque the blade bolts to 115 to 150 N∙m (85 to 110 ft-lb); refer to Figure 103.
Before servicing or removing the mower deck, lock out the spring-loaded deck arms.
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.
Stop engine, wait for all moving parts to stop, remove the key, and engage the parking brake.
Remove the height-adjustment pin and lower the deck to the ground.
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 104).
Rotate the mower deck idler clockwise, lift up on the belt-guide tab, and remove the mower-deck belt from the clutch (Figure 104).
Remove and retain the hardware on both sides of the deck as shown in Figure 105.
Raise the deck struts and secure them in the up position.
Slide the deck out to the right side of the machine.
