Neutral Switch

The neutral switch is a normally open proximity switch
that closes when the traction pedal is in the neutral posi-
tion. The neutral switch is located under the floor plate
near the traction pedal.
Adjusting
1. Before adjusting the traction neutral switch, check
and adjust traction system neutral position (refer to
Traction Unit Operator's Manual).
IMPORTANT: To prevent traction neutral switch
damage, make sure that no components contact
switch through entire traction pedal movement.
2. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch.
3. When the traction pedal is in the neutral position, the
pin on the traction pedal should be centered with the
switch eye. With the traction pushed all the way to the
right, the clearance between the pin on the traction ped-
al and the switch should be no less then 0.07 in (1.8
mm) (Fig. 14).
4. To adjust the switch, loosen the nut securing the
switch to the switch bracket or the nuts securing the
switch bracket to the floor plate and adjust the switch po-
sition as needed.
5. After adjusting the switch, use the Diagnostic Dis-
play (see Diagnostic Display − inputs in the Trou-
bleshooting section of this chapter) to verify that the
switch and circuit wiring are functioning correctly. The
switch should open when the traction pedal is moved in
either direction 0.25" to 1.00" (6.3mm to 25.4mm)
when measured at the top of the traction pedal.
