Bush Hog CBH80 - Manual (Page 46)

SECOND PROCEDURE
ASSEMBLY OF A BUSH HOG BACKHOE
TO A NON BUSH HOG LOADER VALVE -
OR - BUSH HOG BACKHOE TO LOADER
VALVE USING PTO PUMP KIT OPTION.
IMPORTANT:
•
Improper hydraulic hook-up can cause seri-
ous damage to the backhoe control valve,
loader valve, tractor valve, and other hydraulic
components.
•
The pressure supply line from the PTO pump
must be connected to the pressure inlet port
on the backhoe whether using a Bush Hog
loader valve or a non - Bush Hog loader valve.
Never connect the pressure supply line from the
PTO pump to the loader valve pressure inlet port
because excessive pressure will build up result-
ing in damage to the PTO pump.
44
The following instructions are to be used to connect
the backhoe valve in line with a loader valve that is
not a Bush Hog loader valve. When connecting the
Bush Hog backhoe valve to a valve other than one
obtained from Bush Hog, the input pressure line
from the tractor will be connected to the pressure
port on the backhoe first. In order to properly plumb
the system, the backhoe valve will require convert-
ing to a power beyond valve. The power beyond
pressure line from the backhoe valve will be con-
nected to the input pressure port of the loader
valve. The power beyond kit for the backhoe being
assembled must be ordered as a separate item
from Bush Hog.
