Agriculture at all stages of its development cannot be imagined without a plow - a powerful and simple tool for tillage. Over its thousand-year history, it has not lost its popularity and is still used to cultivate the fertile layer of the earth. Only its design and specialization of certain species have changed, where the disk plow is one of the most popular tools.
Destination
It is known that the most popular is the plow plow, which is designed for tillage at all stages of cultivation. However, the use of such a tool in difficult conditions - in wetlands, the place of uprooted forests, stony ground or heavy soils, areas with overgrown vegetation, weeds - is impractical.
Firstly, it will be impossible to achieve a high-quality result - the device simply cannot cope and gets stuck. Secondly, the risk of device breakdown increases, the costs of its maintenance and the amount of fuel necessary for the operation of the drive mechanism increase.
In difficult conditions, it is preferable to use a disk plow. If a ploughshare tool, upon encountering an obstacle, drowns in the ground or breaks, then its quiet counterpart will roll over the obstacle and continue to do its job.
The scope of its application is vast - from after seasonal tillage, to stubble peeling in order to destroy and prevent the appearance of pests and weeds. It is also used in forestry and fire departments: here they plow the land to prevent it from spreading deeper into the forest zone or getting close to settlements.
Disc plow device
By their design, disk devices are plane cutters, that is, they cut the soil without its subsequent dump. Its basis is the front and rear frame. Two rigid disk enclosures are “hung” on each rigid immutable system of beams.
In front of the plow, flat stabilizing knives are mounted, which “punch” the track, outline ditches along which the disks themselves are already moving. It is important that the traces of flat knives and discs match - so you can achieve a better machining result.
A support wheel is also installed on the frame, which serves to control the depth of penetration of the cutting components into the ground.
Directly the working body - the disk - is made of steel, strong, but easily machined alloys that are resistant to corrosion. Their diameter varies from 60 to 80 cm. The cutting elements are distinguished in shape: now there are more than 10 varieties of round knives, which are advisable to use in certain cases.
The benefits of a disc plow
Despite the wide scope and prevalence, the disk plow does not have a sufficient set of advantages to become the most popular and indispensable device for tillage.
Among the positive qualities of this device, agricultural industry experts distinguish:
- Reducing the load on the tractor - by rotating the components during operation, they achieve a decrease in the friction force, which allows to reduce traction.
- High quality surface treatment - due to the fact that the disks are located at a certain angle to the vertical axis, the best penetration of the blades into the ground is ensured.
- Reducing the cost of work - due to the “handling” through obstacles, the risk of damage and dulling of the blades is very low. This also significantly affects the fuel consumed by the traction mechanism.
Like any other equipment of the agricultural sector, the disk plow is mounted. This, on the one hand, allows you to rent a device, reducing losses for downtime, and on the other hand, makes it affordable and simplifies repairs.
Types of Disk Plows
A wide variety of soils suitable for cultivation and subsequent sowing by cultivated plants prompted design engineers to create several varieties of disk plows for various soil conditions. For this reason, now on the agricultural market you can find:
- a device for processing fields - discs here have a diameter of 40-45 cm, which penetrate deep into the earth by 6-10 cm and are located symmetrically relative to the central axes;
- garden tools - round blades of the same diameter are arranged in a checkerboard or asymmetric order, penetrate the soil by 12-14 cm;
- Swamp disk plow - able to plow the earth with excessive moisture, has a large mass and several tens of blades, penetrate the soil by 20-25 cm.
Especially for forestry, several additional elements are installed on an ordinary plow - a turf, a cultivating shovel and a cutter knife.
This simplifies work on the ground with uprooted trees, dense vegetation, near forest zones.
Mobile Disc Plows
For soil treatment in private or summer cottages there is no need to spend large funds and efforts on the purchase and use of professional equipment. To facilitate the processing of the fertile layer of the earth will be able to disc plow-plane cutter for walk-behind tractor.
Unlike industrial tools, such a tool has two to three discs mounted on a metal beam. The connection with the traction equipment is through a rigid coupling. The depth of penetration of the blade into the ground is adjusted by the adjusting screw.
In cases where these devices are not enough for quick and high-quality processing, you can resort to installing attachments on a mini-tractor. In this case, the disk processing tool differs from its perfect brothers only in size.
Pricing Features
The cost of a disk plow depends on many factors. The first of these is destination. Depending on what kind of land you need to plow, it depends on how much you can get to productivity. The choice must be based on traction technology.
The third important indicator is the region of acquisition. Obviously, for the middle strip of Russia, where there is practically no agricultural land, the cost of the device will be relatively low. But for the Volga region, the regions bordering Kazakhstan, the price will be at a fairly high level due to demand.
