Traction (Neutral) Switch (Fig. 8)
The traction switch is normally open and closes when
traction pedal is in neutral.
IMPORTANT: The traction switch has three (3) ter­
minals. Make sure the wires are connected to the
“COMMON” and “N.O.” terminals.
Test switch by disconnecting wires from switch termi-
nals and connecting a continuity tester across COM-
MON and N.O. terminals. With engine off, slowly push
traction pedal in forward and reverse direction while
watching continuity tester. There should be indications
that traction switch is opening and closing. Allow traction
pedal to return to neutral. There should be continuity
across the terminals. (See Replacing Traction Switch in
Repairs section of this chapter for replacement and
adjustment procedures.)
NOTE: Apply “Loctite 271” or equivalent to threads of
switch screws before installing.
PTO Switch (Fig. 9, 10)
The PTO switch is normally open and closes when the
PTO lever is pushed forward to ON position.
Test the switch by disconnecting the wires from the
switch terminals and connecting a continuity tester
across the terminals. With the PTO lever pushed for-
ward (ON), there should be continuity across the termi-
nals. With the PTO lever pulled back (OFF) there should
be no continuity across the terminals. (See Replacing
the PTO Switch in the Repairs section of this chapter for
replacement procedures).
