The motor-block "Neva" can be filled with various structures, from mounted plows to a snow plow. Users claim that this technique is the most popular for use in private estates and on industrial farms. The popularity is due to the versatility of the equipment, average price and practicality. Let's consider in more detail the option with a disk hiller, models, methods of installation and operation.

What it is?

The hiller is one of the types of attachments for cultivators and walk-behind tractors. It is used for hilling potato fields. The design of the unit allows you to uproot vegetables from the ground without the use of manual labor, with a minimum of time and effort. Motoblock "Neva" with a disc hiller is a practical technique in operation due to its design.

The price is high, but it matches the effectiveness of the tool . Furrows after weeding with a disc hiller are high, but it is possible to adjust the height of the ridge due to the correction of the distance between the discs, change the level of penetration and the angle of the blade. When working with a walk-behind tractor, it is worth equipping the equipment with grousers to increase the adhesion of the ground to the wheels of the equipment.

Technical characteristics:

• the ability to regulate the parameters of the width, height and depth of the discs;
• diameter of the working part - 37 cm;
• universal coupling;
• the maximum possible hilling depth is 30 cm.

The first models of disc hillers were equipped with a DM-1K motor; today's models use a foreign-made chain reducer. The carrying capacity of the walk-behind tractor was increased to 300 kg, which makes it possible to fix a trailed cart to it.

Performance has improved to:

• increasing the width of the passage of the treated area;
• the presence of a gearbox with front and rear positions;
• powerful engine;
• ergonomic steering wheel.

In standard models, the technique is made of a rigid frame with two prosthetic wheels with deep tread. Disc hillers 45 x 13 cm in size with a thickness of 4.5 cm. The hilling process takes place at a low speed of up to 5 km / h. Equipment weight - 4.5 kg.

The advantages of the disc hiller:

• no harm to plants after processing the site;
• increased level of productivity;
• reduced degree of physical activity;
• high-quality work performance;
• increasing the fertility and productivity of the land.

Types and models

The Krasny Oktyabr plant produces 4 models of walk-behind tractors. All equipment has no differences in operation and result of work. The differences lie in design features, dimensions, and functionality. A two-row hiller cultivates the land between two rows of crops. Externally, it is made of a rack with a bracket, which is fixed to the hitch, attached to it two racks with hillers, fixed with bolts. This design lends itself to adjustment to suit the conditions of the arable land.

Classification of hillers

Double row

A two-row or lister hiller is of two types OH-2 and CTB. The first model is designed for plowing prepared soil in a small area - for example, a garden, vegetable garden or greenhouse. The maximum penetration of the discs is made to a depth of 12 cm. The height of the equipment is half a meter in height, it is possible to adjust the plowing depth. Weight - 4.5 kg.

The second model is produced in two types, differing in the distance between the width of the working bodies and the body . The maximum penetration into the ground is 15 cm. The distance between the discs is manually adjustable. Equipment weight from 10 to 13 kg. The sliding disc hiller is fixed to the walk-behind tractor using a universal hitch. Discs have the ability to manually adjust. The maximum immersion depth is 30 cm. The height of the equipment is about 62 cm, the width is 70 cm.

Single row

The tool is made up of a stand, two discs (sometimes one is used) and an axle shaft. The stand is fixed with a bracket and a special bracket. This part adjusts the position of the rack in different directions. The shaft allows you to adjust the angle of inclination of the working part. The structure is set in motion by sliding bearings. The weight of the disc tillers is up to 10 kg. The furrows are up to 20 cm high. The angle of inclination of the disc varies up to 35 degrees. Tool height up to 70 cm.

Hiller for MB-2

This hiller has a weaker engine in comparison with the M-23 model, but both of these tools are the same in their qualities and constructive forms. The design is represented by a solidly welded frame with wheels in a rubber tire. The package includes saber-shaped parts on the axle, which will replace the usual wheels during the cultivation of the site.

Rigger with fixed or variable grip

This tool leaves behind a fixed height of the ridges, the row spacing is adjusted before starting work. The fixed hiller is suitable for plowing small private plots. The variable model allows you to adjust the working width for any size of the beds. Of the minuses, shedding of the resulting furrow is noted, leading to a decrease in the efficiency of the plowing process. Hillers models are divided into two types: single-row and double-row types. The second variety is harder to cope with loamy soils.

Propeller type

Placed on walk-behind tractors with two forward gears. The hiller discs have an uneven pattern, similar to rounded teeth. Their task is to crush the soil while uprooting weeds. Loose soil is immediately usable. The streamlined shape of the discs allows you to retain moisture in the soil due to the lowest intensity of work.

Installation

Before starting the collection of the walk-behind tractor with the selected hiller, you must make sure that the equipment is turned off. The first step is to hitch the tool to the walk-behind tractor using a bolt. The working part should be located higher in relation to the walk-behind tractor. The hitch rings are symmetrically aligned with each other. Next, the distance and width between the working parts is adjusted. The setting of the furrow width is controlled by bolts by loosening or repositioning the disc body.

It is worth paying special attention to the symmetry of the distance from the axis to the housings . If the indicators are not observed, the walk-behind tractor will be unstable in operation, constantly tilting to one side, making it impossible to huddle the earth. Adjustment of the angle of attack of the working bodies is carried out to obtain the ridges of the same height. This procedure and changing the distance between the discs can be performed during the operation of the walk-behind tractor.

Hitch for two hillers

Most often, double-row hillers are represented by a welded hitch, without the possibility of independently removing and installing other types of hinges. If the hinge is removable, then fixation occurs on the bracket using special screws. The distance and height of the working surface is adjusted. The distance between the discs must match the row width. Adjustment during operation is not possible. With a strong deepening of the discs during hilling or coming out of the soil, the tool stand must be tilted in the opposite direction, depending on the problem, back or forward.

User manual

With the help of a walk-behind tractor and a hiller, planting, loosening and hilling of the grown crop is carried out. The principle of operation of the technique for collecting potatoes is based on uprooting the root crop from the soil and simultaneously sifting the soil. The collection of the vegetable is done by hand. Hilling of potatoes is done in one row. In this case, you can use vibrating equipment of the KKM-1 class, used on soils with low humidity. The soil itself should not contain more than 9 t / ha stones. Let's take a closer look at the full principle of the hiller's operation. In total, there are several methods for preparing the site before planting potatoes. For this, a controlled technique and a mounted potato planter are used.

Method # 1

Planting culture is performed in the following way:

• lug wheels, disc hiller are hung on the walk-behind tractor, symmetrical furrows are formed;
• a root crop is manually planted in the finished pits;
• the wheels are replaced with standard rubber ones, their width is adjusted, it should be equal to the track width;
• soft rubber does not damage the structure of the root crop and makes it easy to fill and tamp the holes with the vegetable.

Method # 2

Planting a crop using a walk-behind tractor with attachments. This method is used in large cultivated areas. Before starting work, it is necessary to prepare the site in advance: plow the land, create furrows and ridges, moisten the soil. A potato planter is put on the walk-behind tractor, the tinctures of the hiller are adjusted and the potatoes are planted simultaneously, furrows are created and the crop is covered with soil.

After several weeks, when shoots appear, the land on the site is loosened up with a walk-behind tractor and pedestrian rows are created between the bushes . Hilling delivers oxygen and additional moisture to the plant stems, which have a beneficial effect on the growth and development of potatoes. Weeds are uprooted. For these procedures, a two-, three- or single hiller is used. In the course of work, fertilizers are applied to the soil. The hiller also performs temporary weeding of the land between the rows of the crop. When the potatoes are ripe, the standard work of uprooting the potatoes and harvesting is done using a special hiller with plowshares.
