ASSEMBLY OF A BUSH HOG BACKHOE
TO A BUSH HOG LOADER VALVE
IMPORTANT: Improper hydraulic hook-up can
cause serious damage to backhoe control valve or
other hydraulic components. Refer to the Bush Hog
loader Operator’s Manual during this procedure.
When connecting the Bush Hog backhoe valve to a
Bush Hog front end loader valve, the input pressure
line from the tractor will be connected to the loader
valve first. The power beyond pressure line will be
connected to the input pressure port of the backhoe
valve. In order to properly plumb the system, the
loader valve will require converting to a power
beyond valve. Refer to the Operator’s Manual
received with the loader for the proper assembly of
the power beyond valve.
There have been several different valves used on
the loader in past years. The fittings required to con-
vert the Bush Hog loader valve to a power beyond
application are included in the loader valve kit. If the
fittings (or plugs) cannot be located, they can be
obtained from Bush Hog Service Parts. Before
attempting to order the plug you must first determine
the manufacturer of the loader valve assembled to
your loader. This can be determined from the identifi-
cation plate located on the valve.
1. Install the power beyond plug received with the
loader valve into valve cavity as shown in Figure 23
(Page 32). Make sure O-rings on sleeve are posi-
tioned properly and are not pinched or damaged.
2. Install a pressure line (supplied by customer)
between the tractor pressure “out” port and the pres-
sure inlet port of the loader valve.
3. Install a pressure line (supplied by customer)
between the power beyond fitting of the loader valve
and the pressure inlet port of the backhoe valve as
shown in Figure 23.
4. Complete assembly of “return” hoses as shown in
Figure 23. Connect return hoses from both valves to
tee as shown. Hoses and tee supplied by customer.
Connect the return line directly to a port on the tractor
reservoir as shown in Figure 23.
