Electrical Hookup
Refer to Figure 5
Your Turbo-Till is equipped with North American Lights.
Plug the lighting connector into the tractor outlet.
Test the lights and signalling prior to highway movement.
Hydraulic Hose Hookup
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor outlets. Hoses that go to
the same remote valve are marked with the same color.
Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work with system hydraulics.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. If an accident
occurs, seek immediate medical assistance from a physician
familiar with this type of injury.
Use paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.
Refer to Figure 6
To distinguish hoses on the same hydraulic circuit, refer
to hose label.
• The hose with an extended-cylinder symbol feeds a
cylinder base end.
• The hose with a retracted-cylinder symbol feeds a cyl-
inder rod end.
Secure hoses and cables so that they have sufficient
slack for hitch movements, but cannot get caught
between moving parts of tractor, turbo-till or hitch. Failure
to safely route and secure hoses and cables could result
in damage requiring component repair/replacement, and
lost field time.
To distinguish hoses on the same hydraulic circuit, refer
to, “Hydraulic Hose Hookup” on page 15. Clean all
hydraulic couplings and hook hoses to tractor.
