Do not mow wet grass. Wet grass is slippery and the operator can lose footing, slip under the mower, or allow the mower to roll backwards. Wet grass also clogs the discharge chute and can cause the engine to falter. When this happens, always turn off the engine and wait a few seconds for the blades to stop rotating before correcting it. Use care on inclines.
Some slopes are too steep to mow safely, so use good judgment.
Drive riding mowers up and down slopes. Never leave a running mower unattended. When you leave the operator s position the mower should be turned off. New models have an operator presence switch that automatically kills the engine when the operator releases the handle. Disconnect spark plug to service.
