Weight Transfer Preparation
A relief valve prevents operating the wing transfer at
over 103 bar (1500 psi).
Potential Planting Risk
To avoid planting problems, do not exceed
103 bar (1500 psi) for wing transfer, and
69 bar (1000 psi) 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 the wings by
turning the knob clockwise.
 Reduce the weight transfer to the wings by
turning the knob counterclockwise.
3. Set the pressure to at least 17 bar (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 7 bar (100 psi).
4. Secure the setting with the lock ring.
Testing Weight Transfer Adjustments
1. Pull forward in the ground. Check the opener and
coulter 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.
Bypass Valve (S/N C1009F-)
The weight transfer bypass valve must be
adjusted before adjusting the weight
transfer circuit.
A bypass valve is plumbed into the weight transfer
circuit. Tractors with load
- sensing, closed - center
hydraulics require this bypass valve to protect the
tractor hydraulic system.
If unsure what type of hydraulic system is on your
tractor, contact your tractor dealer.
Tractors with Pressure Compensating Closed
Center Hydraulics (PC Closed) - Close the bypass
valve for no oil flow by turning the knob on the valve
clockwise completely. Always operate the drill with
the bypass valve closed.
Tractors with Load Sensing Closed Center
Hydraulics (LS Closed) or Pressure Flow
Compensating (PFC) Systems - The weight
transfer bypass valve must be adjusted to protect the
tractor. Do the following procedure.
Equipment Damage Risk
Failure to use the bypass valve on
load - sensing tractors may cause major
tractor damage.
