in. (62.9 cm) above ground when drill is

lowered in the ﬁeld.

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

sufﬁciently to allow wheel spindle relocation.

3. Relax chain idlers.

4. Remove wheel bolts. Move spindle to new hole pair.

Re-install wheel bolts.
