Safety Interlock Switches
This tractor is equipped with a safety interlock system for the
protection of the operator. If the interlock system should ever
malfunction, do not operate the tractor. Contact an authorized
Troy-Bilt service dealer.
The safety interlock system prevents the engine from
cranking or starting unless the parking brake is engaged,
and the PTO (Blade Engage) lever is in the disengaged
(OFF) position.
The engine will automatically shut off if the operator leaves
the seat before engaging the parking brake.
PTO (Blade Engage)
The engine will automatically shut off if the operator leaves
the tractor’s seat with the PTO (Blade Engage) lever in the
engaged (ON) position, regardless of whether the parking
brake is engaged.
With the ignition key in the NORMAL MOWING position,
the engine will automatically shut off if the PTO (Blade
Engage) lever is moved into the engaged (ON) position
with the shift lever in Reverse.
Engaging the Parking Brake
To engage the parking brake:
1. Fully depress the brake pedal and hold it down with your
foot while gently pushing the parking brake button inward.
2. Hold the parking brake button in while removing your foot
from the brake pedal.
3. Once engaged, the parking brake button and the brake
pedal will lock in the “down” position.
To disengage the parking brake:
1. Slightly depress the brake pedal.
NOTE: The parking brake must be engaged if the operator leaves the
seat with the engine running or engine will automatically shut off.
Setting the Cutting Height
1. Select the height position of the cutting deck by placing
the deck lift lever in any of the six different cutting height
notches on the right side of the fender.
2. Adjust the deck wheels so that they are between ¼-inch
and ½-inch above the ground when the tractor is on a
smooth, flat surface such as a driveway.
WARNING: Keep hands and feet away from the
discharge opening of the cutting deck.
NOTE: The deck wheels are an anti-scalp feature of the deck and
are not designed to support the weight of the cutting deck.
Refer to Leveling the Deck in the Maintenance & Adjustments
section of this manual for more detailed instructions regarding
various deck adjustments.
Starting the Engine
WARNING: Do not operate the tractor if the
interlock system is malfunctioning. This system was
