The potato digger is needed primarily to speed up the harvesting of root crops. The potato processing speed of such technicians is significantly higher than that of manual digging with tools. You can work with a potato digger both in the field and in your personal plot. The main function is to accelerate the separation of tubers from the soil, which are then placed on the loosened soil. Structurally, the potato digger is attached to the gasoline walk-behind tractor through the adapter supplied in the kit.

What is the Agro walk-behind tractor

The potato digger for the Agro walk-behind tractor belongs to the screening type. This is a sophisticated vibrating tool, which is equipped with dividing cells, has a series of sifting rods that filter out the accumulated soil during operation. Under the influence of vibration from the walk-behind tractor and human shocks, the potatoes fall on the grate through the share, where it is gradually cleared of clods of earth. Then the dug up roots are thrown out through the back of the potato digger.

Important! In addition to digging up potatoes, you can use the mechanism for collecting other root crops - onions, beets, garlic.

The mechanical drum potato digger KKM-B is designed specifically for the Agro walk-behind tractor. It was produced by PJSC Ufa Engine-Building Production Association - one of the largest manufacturers of engines for aircraft and helicopters in Russia. At the moment, the company employs more than 20 thousand people. Founded in 1925.

Potato digger

The motoblock of this company belongs to the category of heavy manual agricultural machinery and is considered a professional solution for small-scale mechanization equipment. Its weight is 110 kg. The unit has increased tractive effort, which makes the tillage operations faster. Suitable for working on small farms, as well as farms with large areas. Utilities are used for road works.

Motoblock

The dimensions of the walk-behind tractor for the potato digger are impressive: the height is 110 cm, the width is 85 cm, the length with the handle is 180 cm. The weight of the equipped walk-behind tractor is 150 kg. For work, you will need fuel, which is gasoline marked AI-92. The maximum volume of the fuel tank is 6 liters. The crankshaft is horizontal. Gear reducer.

The description of the unit will impress any gardener. The ground clearance of the walk-behind tractor on base wheels with protectors is 25 cm. The manufacturer has a function of adjusting the track width between the wheels: the limit is 700 mm, the minimum is 500 mm. The turning radius is 1 m, which is quite small for motoblocks of this size. Fuel consumption for 1 working hour from 2 to 6 liters. The nominal energy consumption for continuous work is 390 kW per hour. For work, you will have to make efforts, moving the equipment in 100 kg.

Note! The attachments allow you to work the ground to a depth of 200 mm. By attaching the trolley, you can transport various loads weighing up to 500 kg. In this case, the maximum speed on a flat road can exceed 10 km / h.

Features of the device of a potato digger

The potato digger for Agro has the following dimensions. Height, length and width are 700 mm each. The unit weighs over 40 kg. For an hour of work without interruption, it can process up to 0.2 hectares. The potato digger is capable of loosening the ground at a speed of up to 2 km / h. The machine digs out potatoes to a depth of 20 cm.To turn the potato digger at the outermost point, you need at least 3 m² of area.

The working functions of a potato digger for a walk-behind tractor have the following characteristics:

  • The distance between the lump of earth is 400 mm, the distance between the rods of the screen is 10 mm.
  • The pitch between the rods of the screen is 35 mm.
  • The dimensions of the track rollers are 330 x 90 mm.
  • The track between the wheels is 60 cm.

Note! The potato digger is driven by 2 wheels.

The unit consists of an active knife, also called a ploughshare, and a screening grate - a shaker. Due to the latter, root crops are cleaned from clods of dirt.

Before work, you can adjust the digging depth with the help of road wheels, the rigidity of cutting the soil due to the engine speed of the Agro walk-behind tractor.

Important! Potato digger KKM-2A is suitable for segregated light and medium soils with low relative humidity, not exceeding 27%, with a low content of stones. The maximum soil hardness should not exceed 20 kg / 1 cm².

Comparison with potato diggers on motoblocks Forza, Celina, Ugra

The potato digger for the Celina walk-behind tractor is the same attachment as the potato digger for the Agro walk-behind tractor. It is mounted on pneumatic wheels. The plowing depth is exactly the same as on the KKM-2A. The wheelbase is somewhat narrower and is 600 mm.

The productivity of Celina and KKM for Agro is equal and reaches 0.2 ha / h. The turning radius is also equal, however, the weight of the equipped Target is much higher than that of Agro. It is 50 kg. The dimensions are slightly larger: 700 mm in height, 700 mm in width and 780 mm in length. The track width for processing at Celina is 380 mm, and the width of the rods of the screening mesh is 3.5 cm. It is driven by a belt drive.

Virgin lands

Compared to the complete set for the Agro walk-behind tractor, Celina is practically not inferior in anything, however, its greater weight and dimensions, as well as a narrow track, make it less preferable to purchase.

The Ugra potato digger is distinguished by a slightly shallower digging depth of root crops. The drive works by means of a V-belt transmission through a bevel gear from the shaft. The mass is slightly higher than that of the KKM-2A, and is 45 kg fully assembled. At the same time, it has a weaker power. The working speed is 2 km / h. Dimensions: length 840 mm, width 650 mm, height 740 mm. Against the background of the KKM-2A, it looks like a less logical purchase, but low fuel costs at an equal operating speed and slightly shallower depth compensate for the weaker characteristics.

Potato digger Forza (Forza) of Russian production. Manufactured at the UralBenzoTech plant in Perm. It has an adjustable digging depth. The working width is somewhat narrower than that of the Agro, and is 30 cm. The digger weighs 46 kg. The digging depth is 200 mm, however, Forza has a small size of the shaker bunches - only 10 mm, which is poorly suited for dry and stony soils. The working width of the share is 390 mm. Compared to Agro Forza, it is suitable for soft and loose soil.

Forza Potato Digger

Small pneumatic corrugated wheels, low screen diameter and good working speed are its main advantages. But the dimensions of Forza are larger than those of Agro, and are equal to 875 × 735 × 810 mm. With a larger mass and a small diameter, it is a good choice only for regions with wet soil and a low content of stones per ton of soil.

In the work on the site, many owners of summer cottages and vegetable gardens want to automate the harvesting process. The most difficult stage is the assembly of the root vegetables. In order not to manually collect potatoes, you can use an automatic digger - a potato digger for an Agro walk-behind tractor produced by Ufa PJSC. According to its characteristics, it has almost no competitors among analogues in the price category. The main advantages are low weight, sufficient digging depth and speed of work. This wonderful thing will become an irreplaceable assistant in the household!
