3.2.2 Disc Ridger
Disc ridgers are designed to leave a ridge in
the soil. The disc ridger units are usually
mounted onto the frame in pairs about row
centres however are not limited to this
configuration.
The rotation and angle of the disc ridger units
are altered using bolts positioned in the holes
located at points A and B in the diagram
below. Increasing the rotation (A) will
increase the ridge height. Increasing the disc
angle (B) will increase the cutting and lifting
effect on the soil.
