Grass Deflector G009660 1 The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 2 DANGER 3 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. Contact with rotating mower blade(s) and thrown debris will cause injury or death. 4 • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf.
Installing the Discharge Cover for Mulching Operating Tips 1. Park the machine on a level surface and disengage the blade control switch. 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 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. 2.
at a high cutting height; then mow again two days later at a lower height setting. Avoid Cutting Too Low If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short. Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting.
