disc harrowIt is composed of rake frame, rake group, traction or suspension device and deflection adjustment mechanism. In order to increase the depth of the soil, some light and small rakes are equipped with counterweight boxes on the rake frame. The disc harrows produced and used in the 1980 s distributed a relatively large weight on each disc and had sufficient soil penetration capacity, so there was no need to add weights and adjust the deflection angle. When installing the rake group, the deflection angle of the disc rake group should be fixed at the best position. When shallow tillage is required, wheels controlled by hydraulic cylinders limit the depth.
The towed rake is usually equipped with a device that can automatically adjust the transport state and manually fine-tune the working state on the towing device. With the lifting of wheels and connecting rods, the rake is always level
Commonly used disc harrows have the following configurations:
disc harrowThe left and right sides of a single row of opposite rake groups are arranged in a row, and the left and right rows are respectively composed of one or more concave opposite rake groups. It is used for flats of irrigated land, stubble after harvest and shallow cultivation of fallow land.
Front and rear two rows: each row of disc harrows is symmetrically arranged by two rows of left and right harrows. The concave surfaces of the discs of the first two rows of tine groups are opposite each other. The discs of the rear two rows of rake sets are located between the two discs of the front rake set and opposite the concave surface. In order to avoid the left rake group and right rake group of the opposite rake of the disc rake leaving missing areas at the junction of the left and right rakes, some opposite rakes make the left and right rakes staggered.
The offset type consists of two rows of forward tilt groups, each with an opposing disc concave surface. Since the lateral force of the front and rear rake groups is balanced with the traction, the width centerline of the disc rake may deviate from the longitudinal axis of the tractor during operation, so it is called an offset rake. The bias of the wide bias rake can reach more than 3 meters. When used in orchards, the offset rake can be expanded to the point where it is inaccessible.disc harrowThe tractor works under the hood. Since the offset rake has no missing farming area, it is also widely used in field operations.deep loosening machine,disc ploughIt is also increasingly present in the agricultural sector.

The correct use and maintenance of the disc harrow: in operation, the technical condition of the rake, scraper, square shaft, bearing, angle adjuster and connecting parts should be checked frequently, especially the end nut of the disc harrow group and the fixing bolts of each bearing. If it is found loose, tighten it in time, and remove the weeds and dirt on the workpiece in time.
