Hydraulic Hook-up
!
WARNING!
Escaping fluid under pressure can have sufficient force to pene-
trate the skin. Check all hydraulic lines and hoses before apply-
ing pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
Great Plains hydraulic hoses are colour coded to help you
hook-up hoses to your tractor outlets. Hoses that go to the
same remote valve are marked with the same colour.
To distinguish hoses on the same hydraulic circuit, refer to
plastic hose holder. See Figure 1-7. Connect hose under
extended cylinder to outlet you choose for cylinder exten-
sion. Connect hose under retracted symbol to outlet for
cylinder retraction.

Hydraulic Hose Color Ties
Connect hydraulic hoses from tongue cylinder to one trac-
tor remote valve. Connect hoses from transport-lift cylin-
ders to another tractor remote valve.
Bleeding Hydraulic Systems
For safe and smooth operation, the hydraulic systems
must be free of air. The hydraulic systems should be bled
during initial implement set-up. If they were not bled, or if
you replace a hydraulic component during the life to the
drill, bleed the hydraulics.
Bleeding Tongue Cylinder
1.
Check hydraulic fluid in tractor reservoir and fill to
2. proper level. Add fluid to system as needed. Tongue
cylinder capacity is 1.89 litres (one-half gallon).
3. Raise and safely support hitch, transport frame and
front tongue.
4. Unpin rod end of tongue cylinder. Block, wire or other-
wise safely support cylinder so when rod end is fully
extended it does not contact anything.
5. Cycle cylinder completely in and out at least three
times to purge air from cylinder and hoses.
6. Fully extend cylinder and repin rod end.
7. Recheck tractor reservoir and fill to proper level.
Bleeding Transport Lift Cylinders
The transport-lift cylinders are rephasing cylinders and re-
quire a special procedure for bleeding air from the circuit.
Read and follow procedure carefully. Cylinders will not
function properly with air in the hydraulic circuit.
1. Check hydraulic fluid in tractor reservoir and fill to
proper level. Add fluid to system as needed. Trans-
port-lift-cylinder capacity is about 7.57 litres (2 gal-
lons).
2. Jack up and support hitch frame.
3. Remove 1/2-inch nylock nuts (1) on spring side of cyl-
inder-support brace. Unpin cylinders. Do not alter po-
sition of jam nuts (2) on centre of support-brace bolts.
See Figure 1-8.

Unpin Cylinders
4. Turn cylinders to a position where rod ends are higher
than base ends. Support cylinders in a safe location.
5. Start tractor and run engine at idle speed. With rod
ends higher than base ends, hydraulically extend cyl-
inders. After cylinder rods are fully extended, continue
to hold control lever for one minute before hydrauli-
cally retracting cylinders.
6. Repeat step 5 three times to completely bleed system.
If air is still trapped in either cylinder, it will operate in
jerky, erratic motions. Repeat steps until cylinder
movement is smooth and even.
