Disc Harrow

A: The operating principle of the unit is as follows: while contacting with the field surface, the disc cuts small pieces of soil, lifting them along the inner spherical surface, then the soil falls onto the field surface. On the market, there is a wide range of disc harrows, both domestic and international.

A: A disc harrow is a highly significant agricultural machine widely used to prepare the soil before sowing. It is a timeless piece of farm equipment serving different uses in farming, ranging from ground levelling with heavy soil to eradicating dead grass and preparing a suitable seedbed for getting optimum plant growth.

A: Disc harrows can be divided into three main types, depending on their weight and working depth: Heavy harrows – ideal for deeper harrowing, up to approximately 6-10 cm, Medium-heavy harrows – work at an average depth of 4-6 cm, Light harrows – best for shallow harrowing at 2-5 cm.

A: After the first pass of the disc harrow, the average actual of field capacity was found 0.24 ha/h, and after the second pass of the machine the actual field capacity was found as 0.26 ha/h.

A: In most conditions, the optimal operating speed is approximately 4–6 miles per hour. In sandier soils, discs can be operated up to 8 miles per hour. If you are unsure what the right speed is for your soil conditions, make a few test passes at different speeds and measure the furrow depth.

A: It varies 'from 10 to 25° in single and double action harrows. However, it may be up to 50° in some offset harrows. Penetration increases by increasing gang angle but should be kept low to. avoid plugging in wet soil.

A: Check the tightness of all nuts and bolts and retighten them if necessary;
Lubricate all lubrication cups;
Pour oil and/or grease on all friction points.

A: The concavity, or depth of the curvature of the blade, assists in displacing and aerating the soil. You can measure the concavity by placing the blade on a flat surface with the cutting edges down, then measure through the center hold from the flat surface to the inside edge of the blade center.

A: Also known as disc harrow blades and plow discs, we offer plain and notched disc blades that range from 12 inches in diameter to 36 inches. Disc blade thicknesses range from 2 mm (14 gauge) to 10 mm (3 gauge) to fit your soil conditions.

A: Standard Disc Ploughs are well designed to work in all types of soils & can be use easily in hard soils & in rocky & rooted areas. Standard Disc Ploughs can handle the toughest ploughing jobs with ease. Compatible with a variety of tractors (45 to 75 HP).
