6.Turn ignition switch to the “START” position. Release the switch as soon as the engine starts.

Important: Do Not crank the engine continuously for more than ten seconds at a time. If the engine does not start, allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motor.

Engaging the PTO

DANGER

The rotating blades under the mower deck are dangerous. Blade contact can cause serious injury or kill you.

Do Not put hands or feet under the mower or mower deck when the blades are engaged.

DANGER

An uncovered discharge opening will allow objects to be thrown in an operator’s or bystander’s direction. Also, contact with the blower blades could occur. Thrown objects or blade contact can cause serious injury or death.

Never operate the mower with the hopper or hopper door raised, removed, or altered unless there is a mulch kit in place and working properly.

The PTO lever engages the PTO and blower. Be sure that the hopper is down, the hopper door is securely closed, and all persons are clear of the mower deck and discharge area before engaging PTO.
