Preparation Safety • While mowing, always wear substantial, slip-resistant footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals. These machines meet or exceed ANSI B71.4–2004 specifications in effect at the time of production Improper use or maintenance by the operator or owner can result in injury.
• On multi-bladed mowers, take care as manually • Stop the blades from rotating before crossing • • • • • • • • • surfaces other than grass. When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation. Never operate the machine with damaged guards, shields, or without safety protective devices in place. Do not change the engine governor settings or overspeed the engine.
• Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine. • Avoid sudden starts when mowing uphill because the mower may tip backwards. • Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering. • Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

Hydraulic System Maintenance The reservoir is filled at the factory with approximately 4.7 liters (5 quarts) of high quality tractor transmission/hydraulic fluid. The recommended replacement fluid is as follows: Toro Premium Transmission/Hydraulic Tractor Fluid (Available in 5 gallon pails or 55 gallon drums. See parts catalog or Toro distributor for part numbers.) Alternate fluids: If the Toro fluid is not available, Mobil® 424 hydraulic fluid may be used.
Mower Deck Maintenance Changing the Hydraulic Oil And Filter Service Interval: After the first 200 hours WARNING Every 800 hours 1. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCKED position, and set the parking brake. 2. Move the throttle lever to the SLOW position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut 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 blades daily for sharpness, and for any wear or damage. Sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
Checking for Bent Blades WARNING 1. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCKED position, and set the parking brake. 2. Move the throttle lever to the SLOW position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Rotate the blades until the ends face forward and backward (Figure 94). A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.
2. Check the balance of the blade by putting it on a blade balancer (Figure 96). 3. Note: If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 97). Repeat this procedure until the blade is balanced. Torque the blade bolt to 115-150 N-m (85-110 ft-lb). Correcting the Mower Deck Mismatch If the cut is uneven across the mower swath, correct it as follows: 1.
Adjusting the Blade Pitch Replacing the Grass Deflector Blade pitch is the difference in height-of-cut from the front of the blade plane to the back of the blade plane. Use a blade pitch of approximately 8 mm (5/16 inch). The back of the blade plane should be 8 mm (5/16 inch) higher than the front. 1. Position the machine on a level surface. 2.
Cleaning Note: Place the right J-hook end of the spring around the grass deflector (Figure 100). Important: The grass deflector must be able Cleaning Under the Mower to lower down into position. Lift the deflector up to test that it lowers into the full down position. Service Interval: Before each use or daily Remove the grass buildup under the mower daily. 1. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCKED position, and set the parking brake. 2.
Storage 7. Machine 1. 2. Thoroughly clean the machine, deck, and engine, paying special attention to these areas: • Radiator and radiator screen • Underneath the deck • Under the deck belt covers • Counterbalance springs • PTO-shaft assembly • All grease fittings and pivot points • Remove the control panel and clean out inside of the control box • Beneath the seat plate and top of the transmission Remove, sharpen, and balance the mower blades.
