EMERGENCY STOPPING In the event of an emergency the engine can be stopped by simply turning the ignition switch to STOP. Use this method only in emergency situations. For normal engine shut down follow the procedure given in STOPPING THE RIDER AND ENGINE.
DRIVING PRACTICE - BASIC DRIVING WARNING: Never operate on slopes greater than 17.6% (10°). See SLOPE OPERATION in the safety section. Zero turn riders operate differently from other four- wheeled vehicles. The drive wheels are also your steering wheels. If you cannot drive the unit on a hill, you will not be able to steer the unit on it.

HOW AND WHEN TO WATER, FERTILIZE & AERATE Most lawns are watered too often, but with too little water. However too much water can allow develop- ment of diseases with your lawn. It is best to water the lawn only when necessary, and then to water it slowly, evenly, and deeply—imitat- ing a slow, soaking rain.
Lawn Care & Mowing Information PROPER MOWING SPEED ENGINE SPEED & GROUND SPEED Always operate the engine at full throttle when mowing. If you hear the engine slowing down, you are mowing too fast—maintaining a slower ground speed will improve the cutting efficiency of the blades and prevents many com- mon cutting problems.
