SAFE MOWING GUIDE gency. Learn how to cut and how to keep control of the mower at all times. Many mowers are started manually. When using a pull start or rope start, place your feet firmly and away from the blade. Hold the rope handle securely, but never wrap the rope around your arm or fingers for a “better grip”.

Keep people and pets completely away from the mowing area. Direct the mower’s discharge away from areas where people can be. Planning your mowing pattern has a double benefit. It can reduce chances of an injury and make the clean up after mowing easier.

If you plan to service the unit yourself, follow directions in the Instruction Book. in the rain is no fun and it is dangerous. Always seek shelter in an electrical storm.
SAFE MOWING GUIDE equipped, in FAST position when mowing and bagging. When bagging, slower ground speed will provide the best results. Change the mowing pattern slightly each time you cut. If you always cut the same way, the grass will develop a “set” and clippings will accumulate more heavily in some areas more than in others causing grass to get thinner in those areas. Do not service your mower over the grass. Spilled oil and gas can kill the grass.
