Do – Stop the machine on level ground. not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses.
Operating the Mower Blade-Control Switch (PTO) The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade-Control Switch (PTO) g229111 Figure 18 1. Safe Zone—use the machine here on slopes less than 15 degrees or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15 degrees and near drop-offs or water. 3. Water 4. W=width of the machine g008945 Figure 19 5.
Disengaging the Blade-Control Switch (PTO) Starting the Engine 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. Note: It may be necessary to hold the lever against the stop, in the choke position, while trying to start the engine (Figure 23).
Driving the Machine Shutting Off the Engine 1. Disengage the blades by moving the blade-control switch to the OFF position (Figure 23). 2. Engage the parking brake; refer to Park Position (page 12). 3. Move the throttle control to the FAST position. 4. Turn the key to the OFF position and remove the key. 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.
2. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. To go backward, slowly pull the motion-control levers rearward (Figure 26). 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.
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 or cutting height at 115 mm (4-1/2 inches) as shown in Figure 28. • Bagging • Mulching Height of cut is controlled by the lever located to the right of the operating position (Figure 28). Mow This is the fastest speed.
Adjusting the Anti-Scalp Rollers Operating Tips Using the Fast Throttle Setting For Machines with 107 cm (42-inch) Mower Decks 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 deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
After Operation 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. After Operation Safety Keeping the Underside of the Mower Deck Clean General Safety • Clean grass and debris from the cutting units, Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you or bystanders avoid injury. Refer to your local ordinances for trailer and tie-down requirements.
1. If using a trailer, connect it to the towing vehicle and connect the safety chains. 2. If applicable, connect the trailer brakes and lights. 3. Lower the ramp, ensuring that the angle between the ramp and the ground does not exceed 15 degrees (Figure 31). 4. Back the machine up the ramp (Figure 32). g027995 Figure 32 1. Back the machine up the ramp. 2. Drive the machine forward down the ramp. 5. Shut off the engine, remove the key, and engage the parking brake. 6.
