5317-5323 Hydraulic Down Pressure
This setup procedure is for tractors with closed-center
or pressure compensated flow hydraulic systems.
Open center hydraulics not supported.Adjust down
pressure valve as shown on decal (located on front
right hand truss),
Never leave tractor valve centered when unfolded with
machine in motion. Machine damage may occur when wings
flex up or down
This machine is designed for continuous hydraulic flow to the
wing fold cylinders during field operations. It is for use on
tractors having CLOSED CENTER hydraulics only. If your
tractor has an OPEN CENTER hydraulics, please consult your
dealer for operating instructions.
25. Adjust the bypass/pressure reducing valve by
turning knob clockwise all the way in and then
backing out 1 full turn.
26. On tractor, adjust flow-control valve to low side of
flow rate.
The faster the flow of oil through the system the
greater the potential for oil heating, premature wear or
tractor damage.
27. Lock the fold hydraulic lever for continuous
downward oil flow.
28. Adjust bypass/pressure reducing valve knob on
implement so the pressure gauge reads 1200 psi.
Never exceed 1400 psi.
29. While watching pressure gauge , slowly open knob
until gauge reads 1100psi. Pressure might rise
and then fall off as knob is opened. If pressure
exceeds 1400 psi during this step, the tractor flow is
too high, reduce tractor flow. Lock valve knob at
1100 psi.
30. Finally adjust valve to the desired wing down
pressure setting. Never exceed 900 psi.
31. In field operation, lock the fold hydraulic lever for
continuous downward oil flow. If wings are running
too high, increase pressure setting, knob , to level
machine. If center is too high, decrease pressure
setting with knob on valve.
