Loosely mount the sensor plate to the left lift arm with
(2) 5/16 x 1–1/4 inch carriage screws and flange nuts.
Do not tighten the jam nuts at this time. Position the
sensor plate as shown in Figure 14. Make sure the
switch does not contact the sensor plate.
3.
Start the machine and raise the blower. Stop the
machine.
4.
Adjust the sensor plate until it aligns with the proximity
switch and tighten the carriage screw nuts. Make sure it
does not contact the proximity switch.
5.
Using the jam nuts, adjust the proximity switch up or
down until the gap between the switch plunger and
the sensor plate is 3.8 to 4.3 mm (.150 to .170 inch)
(Figure 15). Torque the jam nuts to 20 N-m (15 ft-lb)
when the gap is attained.

When the switch is adjusted correctly, the blower
should shut off if raised.
Note:
When the traction unit is converted back to a
mowing machine, the PTO will not come on when the front
attachment is in the fully raised position. To engage the
