Smart Speed™ Control System Lever Operation Note: Determine the left and right sides of the machine from the normal operating position. 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 21). 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 6).
Using Stabilizer/Conditioner containers on the ground, away from your vehicle before filling. • 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.
DANGER Operating the machine on wet grass or steep slopes can cause sliding and loss of control. • Do not operate on slopes greater than 15 degrees. • Reduce speed and use extreme caution on slopes. • Do not operate the machine near water. DANGER Wheels dropping over edges can cause rollovers, which may result in serious injury, death, or drowning. Do not operate the machine near drop-offs.
Testing the Safety-Interlock System 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. Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. Wear hearing protection when operating this machine. 1.
Positioning the Seat Adjusting the Tilt The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 10). 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 11). 3.
• A rollover can occur before the tires lose traction. vibration in the machine. Make all necessary repairs before resuming operation. • Avoid operating the machine on wet grass. Tires • Slow down and use caution when making turns may lose traction; regardless if the brakes are available and functioning. and crossing roads and sidewalks with the machine. Always yield the right-of-way. • Avoid starting, stopping, or turning the machine • Disengage the drive to the cutting unit and shut on a slope.
Operating the Mower Operating the Throttle Blade-Control Switch (PTO) You can move the throttle control between the FAST and SLOW positions (Figure 15). The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Always use the FAST position when turning on the mower deck with the blade-control switch (PTO).
Starting the Engine CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Note: A warm or hot engine may not require choking. Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again.
Driving the Machine 2. To go backward, slowly pull the motion-control levers rearward (Figure 20). 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. The throttle control regulates the engine speed as measured in rpm (revolutions per minute).
Stopping the Machine The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. Suggested uses: Trim Parking X Heavy, wet grass X Training X Tow 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.
Adjusting the Anti-Scalp Rollers 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.
Pushing the Machine by Hand 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. Important: Always push the machine by hand. Keeping the Underside of the Mower Clean Do not tow the machine, because damage to the hydraulic drive system may occur. This machine has an electric-brake mechanism. To push the machine, turn the ignition key to the RUN position.
Loading the Machine Note: If the machine fails to move, the electric brake may still be engaged. You can release the electric brake if necessary; refer to Releasing the Electric Brake (page 36). 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 26).
