Tow Hitch Circuits (When Equipped With the Tow Hitch Kit)
Raise and Lower (Fig. 13)
Hitch Offset (Fig. 14)
Whentheremotecontrolhandlelift/offsetswitchisinthe
lift position, all four (4) of the solenoid valves in the tow
hitch manifold are de--energized. In this position, hy-
draulic oil flow from the tow vehicle is available for the
ProCore Processor raise and lower circuits via solenoid
valves S1 and S2. Hydraulic flow to the tow hitch offset
cylinder is blocked by solenoid valves S3 and S4. See
Raise and Lower Circuit Operation in this section for
raise and lower circuit information.

offset position, all four (4) of the solenoid valves in the
tow hitch manifold are energized. In this position, hy-
draulic oil flow from the tow vehicle is available for the
ProCore Processor hitch offset function via solenoid
valves S3 and S4. Hydraulic flow to the lift cylinder is
blocked by solenoid valves S1 and S2. A fixed orifice in
thehydraulicfittingattowhitchmanifoldportC4controls
the offset speed by providing a restriction for the flow to
or from the offset cylinder. Maximum hitch offset circuit
pressure is limited by the pressure relief valve of the tow
vehicle.
