Hydraulic Hose Hookup (Options)
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. Hydraulic fluid injected
under the skin is an extremely serious matter. If such an
accident occurs, seek urgent medical attention from a
physician familiar with this type of injury.
Refer to Figure 8
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.
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.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended
cylinder symbol to the return side of the motor.
These instructions presume a direct tractor-drill 3-point
hitching. If an accessory hitch is used, hose routing and
color coding may vary, and there will be one or two
additional circuits (for the hitch lift and tongue).
13. Connect meter drive hoses to tractor remote valve.
14. The optional hydraulic meter drive requires
continuous flow. If the tractor has only one circuit so
rated, or a priority circuit, use that circuit for the drive.
See “Drive Operational Requirements” on page 68
for circuit requirements.
15. Connect marker hoses to tractor remote valve.
16. If this is the first time the drill has been hitched, bleed
the marker hydraulics per the instructions on
page 114.
