John Deere TOOTH HARROWS - catalog of spare parts

In agriculture, a harrow (often referred to as a set of harrows in the sense of the plural of tantums) is a tool for destroying and leveling the soil surface. Thus, it differs in its effect from the plow, which is used for deeper tillage. Harrowing is often carried out in the fields to follow the roughing left by plowing operations. The purpose of this harrowing is usually to break up clods (lumps of soil) and provide a finer finish, good slope or soil structure that is suitable for use in the seed bed. Such coarser harrowing can also be used to remove weeds and to cover seeds after sowing. Harrows differ from cultivators in that they violate the entire surface of the soil, for example, to prepare the seed bed, instead of breaking only narrow paths that go around the rows of crops (to destroy weeds).

There are four main types of harrows: a disc harrow, a gear harrow, a chain harrow and a chain disc harrow. Initially, the harrows were drawn by draft animals such as horses, mules or oxen, and in some cases, in some places by manual workers. In modern practice, these are almost always mounted implements that are either attached to the tractor via a drawbar or mounted on a three-point linkage.

In cooler climates, the most common types are disc harrows, chain harrows, toothed harrows or toothed harrows, and spring toothed harrows. Chain harrows are often used for easier work, such as leveling the soil or covering seeds, while disc harrows are usually used for heavy work, such as subsequent plowing, to break up the turf. In addition, there are various types of power harrows in which the cultivators are driven from the tractor, and not depending on its forward movement.

Toothed harrows are used to improve the condition of the seed bed before planting, to remove small weeds when growing crops and for loosening inter-row soils, which allows water to be absorbed into the bowels. The fourth is a chain disc harrow. A disk attached to the chains is pulled at an angle to the ground. These harrows move quickly on the surface. The chain and disc rotate to stay clean while breaking the top surface to a depth of about 1 inch (3 cm). Smooth seed prepared for planting in a single pass.

Chain harrowing can be used on pasture land to spread manure and destroy dead material (straw) in the furrow, and also when caring for sports fields, light chain harrows are often used to level the ground after heavy use to remove and smooth loading marks and depressions. When used on arable land in combination with two other types, chain harrowing throws the remaining large clods of soil to the surface, where the weather destroys them and prevents interference with seed germination.

All four types of harrows can be used in one pass to prepare the soil for sowing. Any combination of two harrows is also widely used for various tillage processes. Where harrowing provides a very shallow slope or the soil is very light so that it can be easily blown by the wind, an ice rink is often added as the last set.

Harrows can be of several types and weights, depending on the intended purpose. They almost always consist of a rigid frame to which discs, teeth, coupled chains or other cultivation tools are attached, but the toothed and chain harrows are often supported only by a rigid towing hook in front of the kit.

In the southern hemisphere, the so-called giant discs are a specialized type of disc harrow that can replace the plow in a very rough country, where the plow blade will not process stumps and stones, and the disc plow is too slow (due to the limited number of discs). Giant serrated discs work in a set or in a frame, which is often heavier than concrete or steel blocks to improve the penetration of cutting edges. This type of cultivation is usually immediately accompanied by translational fertilization and inoculation, rather than inoculation or inoculation.

Drag is a heavy harrow.


The Frontier ™ DH Series Disc Harrows feature self-aligning, sealed bearings that protect against dirt, providing reliable, maintenance-free operation and extended service life.


Cast reel serrated blades are standard on the Frontier ™ DH10 Series. These serrated blades aggressively cut and mulch the soil.


Disc washers are easily adjustable to suit changing soil conditions.

Use a more aggressive angle to tear and penetrate rough and uneven soil.

Reduce the angle for a smoother finish for final seedbed preparation.


The iMatch system converts the tractor`s 3-point hitch into fixed hooks and makes attachments very fast.
