Operation

WARNING!
Avoid serious injury or death. Go up
and down slopes, not across. Avoid sudden turns.
Do not operate the tractor where it could slip or tip.
If machine stops going uphill, stop the PTO and back
down the hill safely. Keep safety devices (guards,
shields and switches) in place and working. Remove
objects that could be thrown by the blades. Know
the location and function of all controls. Be sure the
blades and the engine are stopped before placing
hands or feet near blades. Before leaving the
operator's position, disengage the PTO, engage
parking brake, shut off the engine and remove the key.
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 tractor. Contact your authorized dealer.
• The safety interlock system prevents the engine from
cranking or starting unless the parking brake is engaged,
and the PTO is in the DISENGAGED (OFF) position.
• The engine will automatically shut off if the operator leaves
the seat before engaging the parking brake.
• On electric PTO models, the PTO clutch will automatically
shut off if the operator leaves the tractor's seat with the
PTO in the ENGAGED (ON) position, regardless of whether
the parking brake is engaged. On Manual PTO models, the
PTO will disengage if the operator leaves the tractor's seat
with the PTO in the ENGAGED (ON) position, regardless of
whether the parking brake is engaged.
• With the ignition key in the NORMAL MOWING
position, the PTO clutch will automatically shut off if the
PTO is moved into the ENGAGED (ON) position with the
drive pedal in position for reverse travel.
WARNING!
Do not operate the tractor if the
interlock system is malfunctioning. This system was
designed for your safety and protection.
