Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended. Operation Smart Speed™ Control System Lever Before 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 21). Before Operation Safety General Safety Fuel-Presence Window • 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 14). 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 Motion-Control Levers During Operation During Operation Safety Adjusting the Height General Safety You can adjust the motion-control levers higher or lower for maximum comfort (Figure 11). A • The owner/operator can prevent and is responsible for B • • • • • g027252 g027252 Figure 11 • 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.
Operating the Mower Blade-Control Switch (PTO) – Wait for all moving parts to stop. • Do not operate the machine when there is the risk of lightning. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. • Do not use the machine as a towing vehicle. • Do not change the governor speed or overspeed the engine. Engaging the Blade-Control Switch (PTO) • Use accessories and attachments approved by Toro only.
Starting and Shutting Off the Engine Operating the Throttle You can move the throttle control between the FAST and SLOW positions (Figure 15). Starting the Engine Always use the FAST position when turning on the mower deck with the blade-control switch (PTO). 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.
Driving the Machine Using the Motion-Control Levers 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).
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 20). 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. Whenever you change the height of cut, adjust the height of the anti-scalp rollers. Note: Adjust the anti-scalp rollers so the rollers do not touch the ground in normal, flat mowing areas.
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: You can now push the machine by hand. 3 After Operation Safety 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 1 2 g017303 g017303 trailer or truck.
Transporting 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.
Loading the Machine 1 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 26). g027995 Figure 26 1. Back the machine up the ramp. 2 2. Drive the machine forward down the ramp. Important: Do not use narrow individual ramps for each side of the machine.
