Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections. Only
trained personnel should work with system hydraulics.
Escaping fluid u nder pressure can have sufficient pressure to
penetrate the skin causing serious injury.
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 5
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
Color Coded Hose Handles
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip.
• Hoses with an extended-cylinder symbol feed cylinder
base ends.
• Hoses with a retracted-cylinder symbol feed cylinder
rod ends.
Secure hoses and cables so that they have sufficient
slack for hitch movemnets, but cannot get caught
between moving parts of tractor, disk harrow or hitch.
Failure to safely route and sceure hoses and cables
could result in damage requiring component
repair/replacement, and lost field time.
