Operation 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. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel Use Unleaded Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.
Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the gas. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank 1. Shut the engine off and set the parking brake. 2. Clean around each fuel tank cap and remove the cap. Figure 8 1. Clutch/brake pedal 3.
Using the Blade Control (PTO) The blade control (PTO) lever engages and disengages power to the blade. Engaging the Blade 1. Depress the clutch/brake pedal to stop the tractor. 2. Shift the blade control (PTO) lever to Engage (Figure 10). Figure 11 1. Height-of-cut lever Starting the Engine 1. Sit down on the seat. 2. Set the parking brake; refer to Setting the Parking Brake. Note: The engine does not start unless you set the parking brake or fully depress the clutch/brake pedal. Figure 10 1.
Using the Safety Interlock System If the safety interlock switches are disconnected or damaged, the tractor could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. Figure 13 1. Choke 2. Fast • Check the operation of the interlock switches daily and replace any damaged switches before operating the tractor. 3. Slow 4. Throttle lever • Replace switches every 2 years regardless of whether they are operating properly or not.

Remove the KeyChoice key and put it in a safe place out of the reach of children. You could back over a child or bystander while the mower blade or other attachment is engaged and cause serious injury or death. • Do not mow in reverse unless it is absolutely necessary.
Selecting the Ground Speed running, release the parking brake and rise slightly from the seat: The engine should stop. Important: To avoid transmission damage, always depress the clutch/brake pedal before shifting into or out of Reverse. 4. Shift the blade control (PTO) lever into the Disengage position, shift the ground speed lever in Neutral, set the parking brake, and start the engine.
Side Discharging or Mulching the Grass Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with a rotating mower blade and thrown debris will cause injury or death. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. Figure 17 1. Grass deflector 2.
• If the grass is longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual, cut the grass at that setting, and then cut the grass again at the lower, normal setting. • If you must stop the tractor while mowing, you may leave a clump of grass clippings on your lawn. To avoid this, do the following: – Engage the blade and move to a previously cut area.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 5 hours • Change the engine oil. Before each use or daily • • • • • Check the engine oil level.
