Motion-Control Levers and Park Position The motion-control levers are speed-sensitive controls of independent-wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Move the control levers outward from the center to the park position, and exit the machine (Figure 13). Always position the motion-control levers into the park position when you stop the machine or leave it unattended.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • For best results, use only clean, fresh (less than • g014521 Figure 6 1. Fuel-presence window Height-of-Cut Lever The height-of-cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved up (toward the operator), the deck is raised from the ground, and when moved down (away from the operator), it is lowered toward the ground.
Add the correct amount of gas stabilizer/conditioner to the gas. DANGER In certain conditions during fueling, static electricity can be released causing a spark which 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.
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. Think Safety First Operating Safety Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets, or bystanders avoid injury. DANGER g000513 Figure 8 Mowing on wet grass or steep slopes can cause sliding and loss of control. 1. Safe zone—use the TimeCutter here 2.
Understanding the Safety-Interlock System WARNING If 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. 11. Start the engine. 12.
Operating the Blades Stopping the Engine The blade-control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades. This switch controls power to any attachments that draw power from the engine, including the mower deck and cutting blades. Engaging the Blades 1. Disengage the blades by moving the blade-control switch to Off (Figure 12). 2. Move the throttle lever to between the half and full throttle position. 3.
Using the Smart SpeedTM Control System The Smart Speed TM Control-System lever, located below the operating position (Figure 14), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow. g027625 Figure 14 1. Smart speed lever To change speeds, do the following: g004532 Figure 13 1. Park (brake) position 4. Backward 2. Center, unlock position 5. Front of the Machine 3. Forward 1. Move the motion control levers to neutral and outward to the park position. 2.
Driving Forward This is the medium speed. The suggested uses for this speed are as follows: • Bagging • Mulching 1. Move the levers to the center, unlocked position. 2. To go forward, slowly push the motion-control levers forward (Figure 13). Mow This is the fastest speed. The suggested uses for this speed are as follows: • Normal mowing • Transporting the machine g008952 Figure 15 To go straight, apply equal pressure to both motion-control levers (Figure 13).

Loosen the upper bolt holding the control lever to the control-arm shaft. 2.
Transporting the Machine Pushing the Machine 1. Park the machine on a level surface, and disengage the blade-control switch. 2. Move the motion-control levers outward to the park position, stop the engine, and wait for all moving parts to stop before leaving the operating position. 3. Locate the bypass levers on the frame on both sides of the engine. 4. Use a heavy-duty trailer or truck to transport the machine.
g027995 Figure 23 1. Back up ramps 2. Drive forward down ramps 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 24). On flat ground, this requires a ramp to be at least four times (4X) 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 unit moves from the ramp to the trailer or truck.
Operating Tips first mow at a high cutting height, then mow again 2 days later at a lower height setting. Using the Fast Throttle Setting Avoiding Cutting Too Low 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 by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • • • • • Check the safety-interlock system. Check the air cleaner for dirty, loose or damaged parts. Check the engine-oil level. Check the cutting blades. Inspect the grass deflector for damage. After each use • Clean the mower-deck housing.

Electrical System Maintenance WARNING CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. g027959 Charging the Battery Removing the Battery WARNING Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
Charging the Battery WARNING Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Service Interval: Before storage—Charge the battery and disconnect battery cables. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. 1. Remove the battery from the chassis; refer to Removing the Battery (page 32). 2.
Servicing the Fuses Drive System Maintenance The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component/circuit for a malfunction or short. Checking the Tire Pressure Fuse type: • Main—F1-30 amp, blade-type Service Interval: Every 25 hours—Check tire pressure. • Charge Circuit—F2-25 amp, blade-type 1. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Mower Maintenance Releasing the Electric Brake Servicing the Cutting Blades The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized the brake will reset. 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.
