Hydraulic Hose Hookup
Refer to Figure 4
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.
If the tractor has a limited number of remotes capable of
continuous flow, use one for the hydraulic fan. (See
“Specifications and Capacities” on page 137 for tractor
requirements.)
Raising/Lowering Tongue
In addition to hitching, tongue raising and lowering is
required during fold and unfold to engage and disengage
the wing locks. The planter tongue is raised and lowered
by raising and lowering the 3-point.
11. Set the initial tongue height. Distance , measured
at top of tongue tube is:
42 inches (107 cm) above ground level
Additional planter leveling information is found on
page 159.
12. Connect other hydraulic hoses to tractor remotes.
