Hydraulic Hose Hookup
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
Refer to Figure 6
Hydraulic hoses have directional handles and are color
coded to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve pair are marked
with the same color.
To distinguish hoses on the same hydraulic circuit, refer
to the symbols on the handles. Hose under
extended-cylinder symbol feeds cylinder base ends.
Hose under retracted-cylinder symbol feeds cylinder rod
ends.
8. Set tractor circuit for opener lift to float.
9. Plug cylinder base and rod end hoses into circuit
extend and retract ports.
Leveling the Drill
Use hitch turnbuckle to level drill.
Refer to Figure 7
1.

to extend clevises beyond turnbuckle.
3. Retighten jam nuts on turnbuckle.
