Adjusting 3-Point Height
Raising the gauge wheel spindle provides deeper coulter
depth. Lowering the wheel provides shallower depth.
Note: Do not lower coulters to aid in penetrating hard soil.
Instead, increase coulter down-force (page 32).
This may require adding optional weight (page 30).
Refer to Figure 10
1.
Determine new coulter depth desired. With new
discs, the axle holes provide these depths:
2.
Raise drill, unless wheel is already off ground

3.
Relax chain idlers.
4.
