tensioner mounted on the rear of the winch. The
level wind and cable tensioner control the cable so it
winds around the drum in tight, even layers. Power
for operating the winch (winch drive) comes from
the vehicle's engine through the power takeoff
which is connected by a propeller shaft to the power
divider. A forward and a rear propeller shaft are
connected by a universal joint which is supported
by a pillow block extending from the power divider
to the bearing assembly. A sprocket and driver
chain assembly is secured to the winch shaft by a
shearpin. The rear winch control linkage consists of
