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 15 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.
