Set the bypass valve as low as possible while
staying at least 300 psi above the weight
transfer circuit setting.
Tractor Damage Risk
The higher the bypass pressure, the
greater the potential for oil heating and
tractor damage.
While 1800 psi is a good starting point for setting the
bypass valve, if you consistently operate the drill with
low weight transfer circuit pressure you can set the
bypass valve below 1800 psi. If you consistently
operate the drill with very high weight transfer circuit
pressure, you may need a bypass-valve setting
above 1800 psi.
Weight Transfer Preparation
A relief valve prevents operating the wing-transfer
at over 1500 psi.
Potential Planting Risk
To avoid planting problems, do not exceed
1500 psi for wing-transfer, and 1000psi for
cart-transfer.
1. Hitch the drill to a suitable tractor. Hydraulic
power must be available for this adjustment.
2. Unfold the implement. The wing transfer
adjustment cannot be made with the wings
folded. Set the circuit to neutral.
3. Lower the drill in a level area of the field. Pull
forward to put openers in the ground.
Wing Weight Transfer Adjustment
1. Release the lock ring (1) on the wing-transfer
valve.
2. Adjust the knob (2) while watching the gauge (3).
Increase the weight transfer to wings by
turning the knob clockwise.
Reduce the weight transfer to wings by
turning the knob counterclockwise.
3. Set pressure to at least 250 psi.
4. Secure the setting with the lock ring.
Cart Weight Transfer Adjustment
1. Release the lock ring (4) on the cart-transfer
valve.
2. Adjust the knob (5) while watching the gauge (6).
Increase the weight transfer to wings by
turning the knob clockwise.
Reduce the weight transfer to wings by
turning the knob counterclockwise.
3. Set pressure to at least 100psi.
4. Secure setting with lock ring.
Testing Weight Transfer Adjustments
1. Pull forward in the ground. Check the opener and
coulter (option) penetration. Compare the wings
to the center section.
Wing operating height is also affected by a
leveling eye bolt adjustment.
2. During field operations, monitor the coulter and
opener depth of the wings and coulter section.
Adjust the weight transfer as required for
consistent depth across the drill.
