#46675 Control Valve Kit &
#1001420 Hose Kit
General Description
This hydraulic connection uses a single-lever con-
trol valve mounted to the right loader mount with a
mounting plate as shown.
IMPORTANT
■ Hydraulic valves must be connected to the
tractor hydraulic system as shown in the spe-
cific loader mounting kit manual.
■ If hydraulic lines are not connected as shown
in this manual, the loader control valve may be
damaged. A blocked outlet (return) or improper
hose connection will cause pressurized oil to
enter the return circuit and damage the valve.
■ Whenever the engine is running, pump flow
will be present at the Pressure port. Pressure
port must always be connected to the
Power-beyond port with hoses with a 3,000 psi
rating or through an open-center directional
control valve with Power-beyond capability.
Power-beyond control valves have three ports:
inlet, outlet and return-to-sump.
■ Pressure port must never be plugged since
this will cause hydraulic oil to exceed relief,
quickly overheat, and cause damage to the trac-
tor hydraulic system.
■ Never use a directional control valve that
does not have Power-beyond capability (2 hose
connections). Valve spool seal leakage will
occur and the valve housing could fracture.
For installing this control valve kit, references to
right, left, forward, and rearward directions are
determined from the operator’s position in the trac-
tor seat.

■ If the manifold is used to provide hydraulic
power to any implement that is carried off the
ground (such as a front end loader), be sure
that the implement is fully lowered and pres-
sure is relieved before exiting the operator con-
trol area.
