The glow plug light, located near the glow
plug switch, will illuminate when the switch is
depressed. The glow plug light indicates the glow
plugs are preheating the combustion chamber.
Important: Do Not crank the engine
continuously for more then ten seconds at a
time. If the engine does not start, allow a 30
second cool-down period between starting
attempts. Failure to follow these guidelines
can burn out the starter motor and/or fuel
solenoid.
8. Move the throttle to the “SLOW” (if in
“MIDWAY”) and let the engine warm up a few
minutes before moving the throttle to the “FAST”
position.
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.
2. Pull the PTO switch outward to engage the
blades.
3. Place the throttle in the “FAST” position to begin
mowing.
Disengaging the PTO
