Weight Transfer Operation (Option)
This option provides a control valve
, plumbed into the
hydraulic drive circuit, and a cylinder for each wing.
Up to 1000 pounds (450 kg) of mainframe weight may be
transferred to each wing when oil is being supplied to the
hydraulic drive circuit.
Once set, the circuit usually requires little adjustment in
normal field operations. To set the circuit:
1. Unfold and lower the implement name in field
conditions.
2. Supply oil to the hydraulic drive circuit (or operate
the PTO at field rpm if using a PTO pump that
supplies the hydraulic drive). The hydraulic drive
motor itself does not need to be operated.
3. Loosen the lock disc at the valve block. Adjust the
knob until the gauge
reads approximately
1000 psi. Tighten the lock disc.
4. Lower the implement name. Engage the hydraulic
drive (with seeding disabled) Pull forward at normal
field speed for a short distance. Stop.
5. Check that the wings are level.
See page 17 and page 166 for important information
about movements without a suitable tractor. See
page 136 for ordering information.
Monitor Operation
Monitor operation is described in a separate manual
supplied with your implement name.
Operations covered in that manual (and therefore not in
this manual) include:
•
hydraulic drive control
•
seed rate calibration
•
planting rate
•
fertilizer rate
•
setting rate limits and detecting out-of-limits
•
GPS integration
•
fan rpm
•
If the wings ends are lower than the center,
decrease the pressure at the valve .
•
If the wing ends are higher than the center,
increase the pressure.
A relief valve in the valve block prevents any
damage from over-pressure.
