Smart Speed™ Control System Lever Operation The Smart Speed™ Control-System lever, located below the operating position, gives you a choice to drive the machine at 3 speed ranges— trim, tow, and mow (Figure 5). Before Operation Fuel-Presence Window Before Operation Safety You can use the fuel window, located on the left side of the machine, to verify the presence of fuel in the tank (Figure 7). General Safety • Never allow children or untrained people to operate or service the machine.
Using Stabilizer/Conditioner • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device. Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • If you spill fuel on your clothing, change your clothing • Keeps fuel fresh during storage of 90 days or less (drain immediately. Wipe up any fuel that spills.
Checking the Engine-Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level (page 13). Breaking in a New Machine 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.
Positioning the Seat Using the Safety-Interlock System A B WARNING 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.
Adjusting the Tilt You can adjust the motion-control levers forward or rearward for your comfort. 1. Loosen the upper bolt holding the control lever to the control-arm shaft. 2. Loosen the lower bolt just enough to pivot the control lever forward or rearward (Figure 12). 3. Tighten both bolts to secure the control lever in the new position. 4. Repeat the adjustment for the other control lever.
Machines with 107 cm (42-inch) Mower Decks Only The mower deck and mower blades shipped with this machine were designed for optimum mulching and side discharge performance. Removing the Discharge Cover for Side-Discharging 1 1. Park the machine on a level surface and disengage the blade-control switch. 2 2. Move the motion-control levers outward to PARK position, shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

Operating the Ignition Switch Starting and Shutting Off the Engine 1. Turn the ignition key to the START position (Figure 20). Note: When the engine starts, release the key. Starting the Engine 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. Important: Do not engage the starter for more than 5 seconds at a time.
Driving the Machine Shutting Off the Engine 1. Disengage the blades by moving the blade-control switch to the OFF position (Figure 18). The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require sometime for you to adapt to how it moves. 2. Move the throttle lever to the FAST position. 3.
Driving Backward 3. Adjust the lever to the desired position. 1. Move the levers to the center, unlocked position. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. 2. To go backward, slowly pull the motion-control levers rearward (Figure 24). Suggested uses: Trim Parking X Heavy, wet grass X Training X Tow Bagging X Mulching X Mow Normal mowing X Transport X Trim This is the lowest speed.
Stopping the Machine Adjusting the Anti-Scalp Rollers To stop the machine, move the motion-control levers to NEUTRAL and outward to the PARK position, disengage the blade-control switch, ensure that the throttle is in the FAST position, and turn the ignition key to OFF. Remove the key from the ignition switch. For Machines with 107 cm (42-inch) Mower Decks Whenever you change the height of cut, adjust the height of the anti-scalp rollers.
Using the Side Discharge Mowing at Correct Intervals The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
After Operation Note: Do not start the machine. Note: You can now push the machine by hand. After Operation Safety 3 General Safety • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills. • Shut off the fuel before storing or transporting the machine. • Disengage the drive to the attachment whenever you are transporting or not using the machine. • Use full-width ramps for loading the machine into a trailer or truck.
Transporting the Machine Important: Do not use narrow individual ramps for each side of the machine. 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.
