Dealer / Grower Supplied Coulters Procedure
Figure 54
Follow these steps to adjust the counter balance valves:
1. Begin with the fertilizer applicator in the fully folded, transport position.
NOTE: Verify that all cylinder stops are in place before continuing to step 2.
2. Adjust counterbalance valve 3 (CB3) (Item 1) [Figure 54] . Turn adjustment screw all the way in (clockwise). After
adjustment screw is turned all the way in, back the adjustment screw out 1-1/4 turns (counterclockwise).
3. Adjust counterbalance valves 1 & 2 (CB1 & CB2) (Items 2 & 3) [Figure 54] . Turn adjustment screw out
(counterclockwise) so that there are 9 to 10 threads showing above the jam nut on the valve when the jam nut is
tightened.
4. Remove all stops.
5. Using the Transport Circuit, unfold the fertilizer applicator.
6. For further adjustments (See “TROUBLESHOOTING” on page 67.)
Delivery of the fertilizer applicator without factory supplied coulters may require additional adjustment of the
hydraulic system to accommodate the weight of the coulters used. This unknown weight directly affects the
hydraulic pressures in the folding / unfolding and raising / lowering of the toolbar.
Folding and unfolding of the fertilizer applicator toolbar functions are controlled hydraulically by
control valves that rely on pressure to open and close. The different hydraulic pressures in the
cylinders may cause the folding and unfolding functions of the fertilizer applicator toolbar to not
function correctly.
