Seat Switch
With the speed control pedals in the neutral position, the
•
parking brake engaged and the PTO switch in the “OFF”
position, start the engine. Now release the parking brake,
hold down on the back of the operator’s seat against spring
pressure. Release the operator’s seat and the engine should
stop. If the engine does not stop, the seat switch must be
replaced. See an authorized service dealer.
With the speed control pedals in the neutral position,
•
the parking brake engaged and the blade clutch switch
in the “OFF” position, sit in the operator’s seat and start
the engine. Turn the PTO switch to the “On” position and
the blades should start to rotate. Raise up slightly off the
operator’s seat and the blades should stop. If the blades do
not stop when you dismount from the operator’s seat, the
seat switch must be replaced. See an authorized service
dealer.
Electric PTO Clutch
This clutch operates when the engine is running, the operator is
in the operator’s seat and the blade clutch switch is turned on.
This electric clutch is a fairly trouble free device. If a problem
develops and the blades do not turn, first check the 20 amp
fuse in the yellow, 16-gauge wire between terminal “L” on the
ignition switch and the hour meter and then investigate the
wiring harness and the connections to the seat switch, the blade
clutch switch and the electric blade clutch. Then check the seat
switch, the PTO switch and finally the electric blade clutch. If the
PTO clutch is still not working properly, see an authorized service
dealer.
Deck Removal
Remove the mower deck from the tractor as follows:
Lower the deck to the ground. Capture the deck lift by
1.
placing the clevis pin behind the lowest position.

2.
spark plug caps.
Remove tension off the PTO belt by moving the belt
3.
tensioning rod. See Fig. 7-2.
NOTE:
There is a certain amount of spring tension due to
the weight of the deck. When removing the lift linkage
from the deck the tension of the springs will go from the
deck to the deck lift pedal. Not capturing the deck lift pedal
while removing the lift linkage from the deck will cause it
to snap back.
Detach the mower drive belt.
4.
Remove the six linch pins from the right and left side of the
5.
mower and from the front of the mower.
