Headlights
The tractor headlights are turned on whenever the ignition 
switch is turned to either of the run positions. 
Safety Interlock System
The safety interlock system is designed for safe operation 
of the tractor. If this system should ever malfunction, do 
not operate the tractor, immediately contact your Cub 
Cadet dealer. 
The safety interlock system prevents the engine from 
starting unless the parking brake is engaged and the 
PTO switch is in the disengaged (OFF) position.
The safety interlock system will automatically shut 
off the engine if the operator leaves the seat before 
engaging the parking brake.
The safety interlock system will automatically shut off 
the engine if the operator leaves the tractor’s seat with 
the PTO (Blade Engage) switch engaged, regardless of 
whether the parking brake is engaged.
With the ignition key in the NORMAL MOWING position, 
the electric PTO clutch will automatically shut off if the 
PTO switch is in the engaged (ON) position and the 
drive pedal is depressed for Reverse travel.
WARNING: Tampering with or attempting 
to bypass the Safety Interlock Switches in any 
way will void your tractor’s warranty. Do not 
operate the tractor if the interlock system is 
malfunctioning.
