Summary

Safety Rules

General Operation

Read, understand, and follow all instructions on the machine and in the manual before starting.

Slope Operation

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death.

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity.

Safe Handling of Gasoline

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

Assembly

Check Tire Pressure

The tires on your tractor were overinflated at the factory for shipping purposes. Correct tire pressure is important for best cutting performance.

Check Deck Levelness

For best cutting results, mower housing should be properly leveled.

Check Brake System

After learning to operate your tractor, check to see that the brake is operating properly.
