Traction Assist Switch
The traction assist switch is used as an input for the
TEC--5001 controller to energize the solenoid valve in
the traction control manifold. When the traction assist
switch is depressed, hydraulic flow is split equally be-
tween front and rear wheels for enhanced traction. The
traction assist switch only functions when the machine
is in low speed range and in the forward direction. The
traction assist switch is located on the console arm (Fig.
69).
