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 Troybilt 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.

The engine will automatically shut off if the operator leaves the tractor’s seat with the PTO (Blade En- gage) lever in the engaged (ON) position, regardless of whether the parking brake is engaged.

The engine will automatically shut off if the operator engages the PTO with the parking brake ON.

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.

WARNING: Do not operate the tractor if the interlock system is malfunctioning. This system was designed for your safety and protection.

To engage the parking brake:

1.Fully depress the clutch-brake pedal and hold it down with your foot.

2.Move the speed control lever all the way down and into the parking brake position.

3.Release the clutch-brake pedal to allow the parking brake to engage.

To release the parking brake:

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.
