Features of seedbed cultivators

Any sowing work involves soil preparation, during which the top layer of the soil is loosened and optimal conditions for germination and emergence of plants are created. For these purposes, landowners use a seedbed cultivator. This type of equipment is presented in a huge assortment and is characterized by high performance.

Presowing cultivators are disc rollers that have high technical characteristics and are designed to prepare and cultivate the soil before sowing crops.

The main advantages of such devices include:

• a wide range of applications, from cultivation to complete tillage;
• robust construction made of low alloy steel;
• ease of use;
• the ability to adjust the deepening into the soil depending on the type of field work;
• weed removal;
• uniform processing and copying of the relief;
• high efficiency.

As for the drawbacks, the presowing cultivators do not have them, except that each model is designed for a certain amount of work.

In addition, many modifications have a simple design that allows you to customize the mechanisms even in the field.

The presowing cultivator, unlike other types of devices, has a special design, it consists of:

• sturdy frame;
• side and center sections;
• lancet paws;
• recoil shoe;
• hydraulic system;
• drawbar;
• chassis;
• shock absorber;
• spiral roller.

Before starting to cultivate the land, the cultivator is prepared for work. Installation in the transport position is carried out using a hydraulic system, which consists of hydraulic cylinders, fittings, high pressure hoses and quick couplers. In the assembled position, the wings of the device are placed on special stops, they are fixed, give the structure rigidity and make it possible to transport at speeds up to 25 km / h.

Adjustment of the tillage depth is carried out by means of stop screws.

Today, the market is represented by a huge selection of pre-sowing equipment, while Russian-made cultivators are very popular among farmers. They are of high quality, reasonable price and long service life.

Reliable modifications include the KBM-7.2P cultivator... The type of this device is trailed, the maximum operating speed is up to 10 km / h, the transport speed is 20 km / h. It is designed for fallow treatment, weed cutting and is ideal for all types of land, regardless of the climatic zones where the plots are located.

In addition, the manufacturer has provided in such a cultivator the possibility of changing the depth of soil cultivation and changing the angle of inclination of the screen, which greatly simplifies the work.

The main element in the design is the roller, it is used for crumbling the dry layer and consists of two parts: a front with a diameter of 27 cm and a rear with a diameter of 21 cm.The parts are interconnected by spring levers, due to the fact that the elements have different diameters, they rotate at different speeds and crumbles the topsoil well.

The hydraulic system of the device is represented by four couplings, hydraulic cylinders and high pressure hoses.

On sale you can also find pre-sowing cultivators KBM-6, they are analogous to the previous model and differ little from it in terms of technical characteristics. Such devices are most often used for soil cultivation, the moisture content of which does not exceed 28%. Their ground clearance is 30 cm and the maximum transport speed does not exceed 20 km / h.

Kompaktomat K1250 PS is characterized by a more compact appearance, in addition to this, the design has been improved. It provides both heavy and medium rollers of slatted, tubular and gear type. Due to the fact that the leveling bar is controlled by the hydraulic system from the tractor cab, it is possible to level even large irregularities, including chill.

The cultivator tines are spring-loaded, they are placed in four rows and can be mounted on paws up to 17 cm wide.

Presowing cultivator KBM-8PS has a wide-cut skating rink (8 m), capable of deepening into the ground by 8 cm, the structure rack is low (40 cm), it is placed in three rows. The width of the paws is 15 cm, the working speed of the device reaches 12 km / h, its productivity is 9 ha / h. This model was developed by the engineers of the Russian Academy and has successfully proven itself for its reliability and long service life.

The cultivator qualitatively prepares the soil for sowing crops such as mine, rapeseed, beets, corn and sunflowers, providing good loosening.

All seedbed cultivators are supplied complete with the main working tools that allow rolling, leveling and crushing the soil. At the same time, when buying these devices, it is important to pay attention to their technical characteristics, which would correspond to the scope of work and the size of the site.

The main indicators when choosing a particular model are the following.

Since these parts take part in loosening and mixing the soil, preference should be given to those that are made of durable metal and have large dimensions.

These implements are available in various types and, depending on the type of soil cultivation, can be installed in different places of the frame. To increase their efficiency, it is recommended to additionally use a spring-roller attachment.

When buying, you need to pay for the width of its coverage.

Presowing cultivators are designed to prepare the soil before sowing crops, but changing their configuration can increase productivity and expand functionality. To obtain a universal device, the structure must contain a spring strut, lancet arms, bar leveling, a rotary roller and support wheels.... Thus, it will be possible to carry out cultivation, loosening and processing of virgin lands.

For spring plowing it will be necessary to supplement the cultivator with reversible tines and toothed leveler... If it is planned to sow beets, then a double rotary roller is installed in the design of the device.

You can increase the speed of processing plots by using a cultivator with tractors of high power. For such work, not only double support wheels are installed in the structure, but also single ones along the extreme modules.
