Starting the Engine Operating the Blades Note: A warm or hot engine may not require choking. The blade-control switch 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. Important: Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 60 second cool-down period between attempts.
Driving the Machine This machine has the characteristics of both a garden tractor and a zero-turn machine. Like a garden tractor, the machine has a foot pedal that controls the forward and reverse motion along with the speed, and it has a steering wheel that controls the direction and the turning radius. Like a zero-turn machine, the rear drive wheels operate independently of each other, enabling you to make sharp turns and to turn in different directions quickly.
DANGER A child or bystander could be backed over by a riding mower with blades engaged and cause serious personal injury or death. • Do not mow in reverse unless absolutely necessary. • Always look backward and down before backing up. • Use the KeyChoice switch only if you are certain no children or other bystanders will appear in the mowing area.
Positioning the Steering Wheel • Upper hole—use this position with the mower The steering wheel has 3 positions for operation and 1 full-up position. Use the full-up position for stepping on and off the machine and getting out of the seat. When operating the machine, position the steering wheel where you have the best control of the machine and are most comfortable. • Lower hole—use this position with the deck in the 63 mm (2-1/2 inch) and below height-of-cut positions (Figure 17). 1.

To push the machine, the ignition key needs to be in the RUN position. The battery needs to be charged and functioning for the electric brake to be disengaged.
Using the Grass Deflector Transporting the Machine The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 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.
Loading the Machine WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. Use extreme caution when loading or unloading machines 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 21). • Use extreme caution when operating a machine on a ramp.
Operating Tips Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST 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.
drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward. Keeping the Underside of the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
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.

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 or circuit for a malfunction or short. Checking the Tire Pressure Fuse type: • Main—F1-30 A, blade-type Service Interval: Every 25 hours—Check the tire pressure. • Charge Circuit—F2-25 A, 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 can be release by manually rotating the link arms forward. Once the electric brake is energized, the brake will reset. Maintain sharp and balanced 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.
