3.

Loosen the jam nut and unscrew the switch from the

mounting bracket.

4.

Screw the new switch through the mounting bracket

until the switch button is about 1/16 in. (1.6 mm)

shorter

than the top of the seat return spring pin. Install

the boot into the mount grooves.

5.

Carefully release the seat to its normally down position,

but do not sit or apply force on the seat. There should

be a slight gap between the switch and the seat plate.

6.

Lock the switch in place by tightening the jam nut to

75 in.-lb. (8 N

⋅

m) against the mounting bracket.

Important

The switch threads will be damaged if the

jam nut is overtightened.

7.

Connect a continuity tester or ohm meter to the switch

terminals. With the seat in the down position and no one

on the seat, the switch circuit should 

not

 have

continuity. If there is continuity, repeat steps 4–6. If

there is no continuity, proceed to step 8.

8.

Sit on the seat. The seat switch 

should 

have continuity.

If there is no continuity, repeat steps 4–7. If there is

continuity, proceed to step 9.

9.

Plug the switch connectors together.

Replacing the Traction Switch

1.

Pivot the seat forward and secure it with the support

rod..

2.

Unplug the switch connectors from the traction switch

installed in the valve bank bonnet on the selector valve

section (Fig. 50).

3.

Loosen the jam nut and unscrew the switch from the

mounting bracket.

4.

Move the shift selector to Neutral.

5.

Partially screw the new switch into the bonnet.

6.

Connect a continuity tester or ohm meter to the switch

terminals and continue to turn the switch in until there

is continuity. Then rotate the switch in 1/2 turn (180

degrees).

7.

Tighten the jam nut to 75 in.-lb. (8 N

⋅

m) against the

bonnet.

Important

The switch threads will be damaged 

if 

the

jam nut is overtightened.

8.

Connect a continuity tester or ohm meter to the switch

terminals and move the shift selector to the #1 and #2

positions. There should 

not 

be continuity when the shift

selector is in either of these positions. If there is

continuity, repeat steps 5 and 6.

9.

Move the shift selector lever to Neutral and connect a

continuity tester or ohm meter to the switch terminals.

The switch 

should 

show continuity. This means the

switch is operating correctly.

10.

Plug the switch connectors together.

Replacing the Mow/Lift Switch

Important

The spool travel for the 1, 2, and 3 spools

must be correct before the mow/lift switch can be adjusted;

refer to Adjusting the Rear Camshaft, page 33.

1.

Pivot the seat forward and secure it with the support

rod.

2.

Unplug the switch connectors from the end of the

mow/lift switch installed in the valve bank bonnet

(Fig. 50).

3.

Loosen the jam nut and unscrew the switch from the

valve bank bonnet.

4.

While holding the lift pedal in the fully depressed

position (the valve bank spools are fully in) partially

screw the new switch into the bonnet.
