and in this manual before operating.
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 MTD service dealer.
The safety interlock system prevents the engine
from cranking or starting unless the parking brake is
engaged, and the PTO (Blade Engage) knob 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
engages the PTO with the parking brake ON.
The electric PTO (Blade Engage) clutch will
automatically shut off if the operator leaves the
tractor's seat with the PTO (Blade Engage) knob in
the engaged (ON) position, regardless of whether
the parking brake is engaged.
With the ignition key in the NORMAL MOWING
position, the electric PTO (Blade Engage) clutch
will automatically shut off if the PTO (Blade
Engage) knob is moved into the engaged (ON)
position with the shift lever in Reverse.
