8. Connect all other hydraulic hoses.
9. Connect any remaining electrical cables, page 20.
10. Extend the Hitch/Lift circuit to raise the hydraulic
tongue just enough to relieve pressure from the
parking stand.
11. Remove and store main tongue parking stand. See
“ Store Main Parking Stand ” on page 20.
Raising/Lowering Tongue
In addition to hitching, tongue raising and lowering is
required during fold and unfold to engage and disengage
the wing locks.
With the standard 3-point hitch, the planter tongue is
raised and lowered by raising and lowering the 3-point.
With the optional hydraulic tongue, the planter tongue is
raised by extending the hitch cylinder, and lowered by
retracting the hitch cylinder.
Local Float on Hydraulic Tongue
Refer to Figure 5
The hydraulic tongue must be in Float during planter
moves.
If it is necessary to move the planter without first
connecting it to a tractor that has a float-capable circuit
for the hydraulic tongue, open the bypass valve
on the
tongue cylinder. This provides local floating capability at
the tongue.
Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Relieve 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. 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.
Only trained personnel should work on system hydraulics!
