Bush Hog 2175 Lawn Mower User Manual


 
Tractors with an auxiliary hydraulic flow greater
than 15 gpm
Connect JIC swivel run tee (9) to 90° male adapter (10)
on “K2” port on valve as shown in Figure 27.
IMPORTANT - The location of the JIC swivel run tee
will ensure that proper flow is provided to the back-
hoe for smooth operation. The flow into the valve
from the tractor is divided between the two outlet
ports “K2” and “K3”. The hydraulic flow is split so
that 60% is flowing from the “K2” port and 40% is
flowing from the “K3” port.
4. Assemble 90° JIC adapter (8) to branch port of
swivel run tee fitting (9).
5. Assemble 45° JIC adapters (7) to both
In/Pressure and Out/Return ports on the back-
hoe bulkhead connection.
6. Connect 24 hydraulic hose (11) between 45° JIC
adapter (7) on backhoe In/Pressure bulkhead
connection and single 90° male adapter (10) locat-
ed under flow divider valve.
7. Connect 24 hydraulic hose (11) between 45° JIC
adapter (7) on backhoe Out/Return bulkhead con-
nection and JIC swivel run tee (9) on flow divider
valve.
8. Assemble quick coupler (supplied by customer) to
pressure line hydraulic hose (supplied by customer)
and connect free end of hose to 90° male adapter
(10) at top of flow divider valve.
9. Assemble quick coupler (supplied by customer) to
return line hydraulic hose (supplied by customer)
and connect free end of hose to 90° JIC adapter (8)
on flow divider valve.
10. Carefully route pressure and return line hydraulic
hoses to tractor remote hydraulic connections.
Remove dust caps from tractor remote hydraulic
connections and connect hoses to the appropri-
ate port on tractor.
Testing Backhoe Hydraulic Hook-Up
1. Start tractor engine.
2. Set parking brake and engage tractor remote
hydraulics so that oil flows to backhoe. NOTE!
Consult tractor Operators Manual for proper
operation.
3. Exit tractor and sit in backhoe operators seat.
4. To remove air from backhoe hydraulic system,
slowly cycle all backhoe functions (stabilizers,
boom, dipperstick, bucket, and swing) several
times. Be sure to cycle stabilizers first and then
lower both stabilizer arms into operating position
before cycling other backhoe functions.
5. Exit backhoe, disengage tractor remote
hydraulics, stop engine, and check tractor
hydraulic fluid level.
Backhoe Mounted to Skid Steer Loader
1. Assemble 90° male adapter (10) to inlet port at
bottom of flow divider valve as shown in Figure 28.
2. Assemble flow divider valve (5) to Great Bend
skid steer adapter using 5/16 x 2-1/2 bolts (1) and
lock nuts (3), 5/8 x 1 bolts (2), 5/8 lockwashers (4)
and valve mount plate (12). Orient valve so that
wording on valve can be read after valve is mounted
to skid steer adapter.
3. Assemble remainder of fittings to flow divider
valve according to instructions that follow.
