Disc harrow harrow group configuration form

Commonly used disc harrows have the following configurations:
1. Single row opposed type
The left and right sides of the rake components are arranged in a single horizontal row, and the left and right rows are each composed of one or more rake groups with opposite concave surfaces. Used for leveling of irrigated lands, post-harvest stubble removal and shallow tillage of fallow lands.
2. Double row opposed type
There are two columns, front and back. Each column is symmetrically configured by two rows of rake groups on the left and right. The concave surfaces of the discs of the two rows of rake groups in the front row are opposite to each other; the discs of the two rows of rake groups in the back row are between the two discs of the rake group in the front row and are opposite to their concave surfaces. In order to avoid leaving a leakage zone at the junction of the left and right harrow groups of opposing harrows, some opposed harrows stagger the left and right harrow groups.
3. Offset type
It consists of two rows of rakes with front and rear rows of discs with opposite concave surfaces. Since the lateral force and traction force on the front and rear rows of rake groups are balanced, the width center line of the rake can deviate far from the longitudinal axis of the tractor during operation, so it is called an offset rake. The wide offset harrow has an offset of over 3 meters. When used in orchards, the offset rake can reach under the tree canopy where tractors cannot enter; because the offset rake does not miss the plowing zone, it is also widely used in field operations.
