Slope Operation

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Mow up and down slopes (10 degrees maximum), not across.

• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

• Choose a low ground speed so that you will not have to stop while on the slope.

• Do not mow on wet grass. Tires may lose traction.

• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope.

• Keep movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause machine to roll over.

• Use extra care while operating machine with grass catchers or other attachments; they can affect the stability of the machine.
