Using the Grass Deflector 5. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Tie down the machine near the front caster wheels and the rear bumper (Figure 21). Note: Avoid the steering components and mower deck parts when tying down the machine at the front caster wheels. DANGER Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.
WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Use only a full-width ramp; do not use individual ramps for each side of the machine. • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck. • Ensure that the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground.
Operating Tips raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. 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.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
