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 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 37). 4. Back the machine up the ramp (Figure 38). g027995 Figure 38 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.
