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
blade could occur. Thrown objects or blade
contact can cause serious injury or death.
Never operate the mower with the discharge
deflector raised, removed, or altered unless
there is a grass collection system or mulch
kit in place and working properly.
The PTO push-pull switch engages the cutting blades.
Be sure that all persons are clear of the mower deck
and discharge area before engaging PTO.
Important: Operator must be in seat before the
PTO can be engaged.
1. Set the throttle midway between the “SLOW”
and “FAST” positions.

blades.
3. Place the throttle in the “FAST” position to begin
mowing.
