Motion-Control Levers Height-of-Cut Lever Use the motion-control levers to drive the machine forward, reverse, and turn either direction. The height-of-cut lever works with the foot pedal to lock the deck in a specific cutting height. Adjust the height of cut only when the machine is not moving (Figure 6). Park Position Hour Meter Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 21).
Operation • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle. Note: Determine the left and right sides of the machine from the normal operating position. • Do not operate the machine without the entire exhaust system in place and in proper working condition.
Using Stabilizer/Conditioner A B C Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • Keeps fuel fresh during storage of 90 days or less (drain the fuel tank when storing the machine for more than 90 days) D • Cleans the engine while it runs • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting Important: Do not use fuel additives containing methanol or ethanol. E Add the correct amount of fuel stabilizer/conditioner to the fuel.
Using the Safety-Interlock System DANGER Wheels dropping over edges can cause rollovers, which may result in serious injury, death, or drowning. WARNING Do not operate the machine near drop-offs. If the 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.
Testing the Safety-Interlock System Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 12). Test the safety-interlock system before you use the machine each time.

Driving Forward Using the Smart SpeedTM Control System Note: Always use caution when backing up and turning. The Smart Speed TM Control-System lever, located below the operating position (Figure 24), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow. 1. Move the levers to the center, unlocked position. 2. To go forward, slowly push the motion-control levers forward (Figure 22). g027625 Figure 24 1.
Tow Adjusting the Height of Cut This is the medium speed. The suggested uses for this speed are as follows: Note: The transport position is the highest height-of-cut position at 115 mm (4-1/2 inches) as shown in Figure 25. • Bagging • Mulching Mow This is the fastest speed.
Operating Tips 4 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. G010233 3 1 2 g010233 Cutting a Lawn for the First Time Figure 26 1. Anti-scalp roller 3.
