Operation Note: Determine the left and right sides of the machine from the normal operating position. • Do not operate the machine without the entire exhaust • Before Operation • Before Operation Safety • General Safety • • Never allow children or untrained people to operate or • • • • • • service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
Breaking in a New Machine Important: Do not use fuel additives containing methanol or ethanol. New engines take time to develop full power. Mower decks and drive systems have higher friction when 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. Add the correct amount of fuel stabilizer/conditioner to the fuel. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel.
CAUTION This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Use protective equipment for your eyes, ears, hands, feet, and head. 1 2 g027830 g027830 Figure 8 G009027 1. Safe Zone—use the machine here on slopes less than 15 degrees or flat areas. 2.
Testing the Safety-Interlock System Using the Safety-Interlock System 1. Sit in the seat with the engine off and ensure that the PTO switch is in the OFF position. 2. Turn the ignition key to the START position; the starter should crank. Do not start or shut off the engine prior to step 3. WARNING If safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly causing personal injury. 3. Turn the key to the ON position and push the Smart Park switch to the OFF position.
Positioning the Steering Wheel the FORWARD or REVERSE position. The brake should disengage and the brake light should turn off. 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.
Operating the Smart Park™ Parking Brake • Keep your hands and feet away from the cutting units. Keep clear of the discharge opening at all times. • Look behind and down before backing up to be sure of a clear path. The parking brake is activated electronically. • Use care when approaching blind corners, shrubs, trees, Engage the parking brake by 1 of the following actions: or other objects that may obscure your vision.
Operating the Ignition Switch 1. Turn the ignition key to the START position (Figure 16). Note: When the engine starts, release the key. Important: Do not engage the starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor. Note: You may need multiple attempts to start the engine when you start it the first time after the fuel system has been without fuel completely.
Driving the Machine Starting and Shutting Off the Engine 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.
Stopping the Machine 4. Perform the mowing. To shut off the machine, release the traction-control pedal, disengage the blade-control switch, ensure that the throttle is in the FAST position, engage the parking brake, and turn the ignition key to off. 5. When finished mowing, remove the Key Choice key (Figure 6).
Using the Grass Deflector Operating Tips The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 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.
Pushing the Machine by Hand Keeping the Underside of the Mower Clean Important: Always push the machine by hand. Do not tow the machine, because damage may occur. 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. This machine has an electric-brake mechanism, and to push the machine, the ignition key must be in the RUN position.
Operating the Machine Loading the Machine Move the bypass levers rearward through the keyhole and down to lock them in place as shown in Figure 20. 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 up the ramp and drive forward down the ramp (Figure 22). Note: Do this for each lever. Transporting the Machine Use a heavy-duty trailer or truck to transport the machine.
