Operation Side Discharge Transporting Machines The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Use a heavy–duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Please carefully read all the safety instructions on pages 3–13. Knowing this information could help you, your family, pets or bystanders avoid injury.
Operation Loading Machines Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward.
Operation Tips for Mowing Grass Fast Throttle Setting Cutting Speed To improve cut quality, use a slower ground speed. For best mowing and maximum air circulation, operate the engine at “FAST.” Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
