SLOPE GUIDE
USE THIS PAGE AS A GUIDE TO DETERMINE SLOPES WHERE YOU MAY NOT OPERATE SAFELY.
Operate ZERO-TURN mowers across the face of slopes, never up and down slopes.
Operate WALK-BEHIND mowers across the face of slopes, never up and down slopes.
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). A riding mower
could overturn and cause serious injury. If operating a walk-behind mower on such a slope, it is extremely difficult to maintain
your footing and you could slip, resulting in serious injury.
