Question
The disc plough is designed to work in all types of soil
for functions such as soil breaking, soil raising, soil turning and soil mixing. Tilt angle of a disc plough is generallySolution
Tilt angle - It is the angle at which the plane of the cutting edge of the disc is inclined to a vertical line. The tilt angle varies from 15° to 25° for a good plough.
