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.
Refer to Figure 5
Hose Handles
To distinguish hoses on the same hydraulic circuit, refer
to, “Hydraulic Hose Hookup” on page 14. The hose
under an extended symbol feeds a cylinder base end.
The hose under a retracted-cylinder symbol feeds a cylin-
der rod end.
Clean all hydraulic couplings and hook hoses to tractor.
First Time Field Adjustments
Pre-Leveling of Machine
Front to Rear Leveling
Refer to Figure 6
1.
Pre-leveling of machine can be done on a concrete
slab or level surface. Lower machine so sweeps are
2-3” off of ground on the center frame. Adjust turn-
buckle at the front of machine to level it from front to
back. (Shorten to bring front down, extend to bring
front up). Level machine with the front row just
slightly deeper or lower than the back.

High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing seri-
ous injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics.
