Weight Transfer
During field operations, the fold cylinders distribute
center section weight to the wings. The center section
weighs more than each wing (substantially more with
optional weights). The drill’s hydraulic Fold/Field valve
needs an initial setting and possible later adjustment.
If insufficient weight is transferred, the wings will run
higher than the center section. If excess weight is
transferred, the center runs higher.
Refer to Figure 46
1.
Lower drill.
2.
Set valve selector handle
to Field (down) position.
3.
On seed monitor terminal, set Fold function On via
soft key.
4.
Engage Fan/Fold circuit on tractor (normally Extend).
5.
Release lock ring
on drill valve.
6.
Adjust knob
while observing gauge
.
• Increase weight transfer to wings by turning knob
clockwise.
• Reduce weight transfer to wings by turning knob
counter-clockwise.
7.
Set initial pressure as follows:
To avoid equipment damage, do not exceed 800 psi.
8.
When satisfied with pressure reading, raise
implement while watching pressure gauge. Gauge
reading should drop as you raise implement.
9.
Tighten lock ring
.
Note: If wings run lower than center section when at
minimum pressure setting, add weight to center
section. see “Frame Weight” on page 41.
During field operations, monitor opening depth of wings
and center section. Adjust weight transfer as required for
consistent depth across drill.
