Neutral Switch Adjustment
If the engine does not start unless one or both of the steer-
ing control levers is moved, then one or both of the neutral
switches will need to be adjusted.
When the steering control lever is in the neutral position,
the cap screw on the steering control lever should align with
the target circle on the neutral switch. If it does not, then the
neutral switch will need to be adjusted.
1. Place the steering control lever in the neutral position.
2. Loosen the two cap screws that hold the switch. Slide
the switch in the slot to move it forward and backward.
Figure 7-1
3. Loosen the nut on the steering control lever and slide
the cap screw up and down to align the end of it with
the target circle as shown. Tighten nut. Figure 7-1
NOTE: The gap between the end of the cap screw and
the target circle surface should be between .010" and
.060”. The end of the cap screw and the target surface
should not touch.
4. After the cap screw and target circle are aligned
tighten all the hardware.
5. Repeat the procedure, if necessary, for the opposite
switch.
NOTE: If the neutral switch is replaced use the .20" spacer
that is supplied with the switch.
Operator Presence Switch Adjustment
The operator presence switch will need to be adjusted if
the engine dies when the deck clutch is engaged and while
the park brake is disengaged:
1. Loosen the hardware that attach the plunger bracket
to the mower frame. Figure 7-2
2. Adjust the plunger bracket so that the spring is not
loose but it is not engaging the operator presence
switch. Figure 7-2
3. Tighten the plunger bracket hardware.
