Pros and cons of the PTO models

Many people find the simplicity of the model attractive and the possibility of operating two eccentrics at the same time. But they have specific nodes. silent-blocks, which can’t withstand regular loads, wear out and need repair or replacement. The conveyor belt models are more reliable in this respect. They have special gearboxes that allow them to optimize their work. Thanks to their design, it is easy to change the speed of the belt according to the ground conditions. Instead of silent blocks they are equipped with bearings, which also increases the reliability of equipment.

If you compare in terms of efficiency, there is no fundamental difference between the models. The conveyor model may be superior in that after it the harvest remains on the ground. And screeners leave the crop slightly mixed in with the soil.

Characteristics of screen models

Their well-known representatives: KKM-1, KKM-3, “Poltavchanka”, KM-1 for MTZ power tiller.

Potato digger KVM-3

The design consists of an active ploughshare and a screen. The area for maneuvering equipment should be at least 60-70 cm. in width. The blade undercuts the soil layer, where the sieve is embedded. The vibrating action sifts the soil and separates the crop. The vibration force is strong enough to sift through large, clumpy chunks of soil. After sifting the crop remains on the surface of the ground.

  • wide coverage of the soil. eliminates crop residues in the soil;
  • separates the soil well from the potatoes;
  • can be used to dig out other crops: garlic, beets, carrots, etc.д.;
  • ease of operation;
  • economical use of fuel;
  • Optimal for working on large areas of ground.

Advantages and disadvantages of fan harvesters

Fan models are shovel-like mechanisms with concave edges. Metal rods are welded to the edges. Digging is done with sharp ends. Has the following disadvantages and advantages.

Fan spudger

  • easy to mount on a single-axle tractor;
  • compatible with power tillers that have a minimum motor power. For example, this is the Neva MB;
  • reliable design;
  • high productivity;
  • The simplicity of their construction allows them to be built to order in any region;
  • affordable price.
  • Fan models can work a small area of the ground. it is usually up to 20 cm. to a width of up to 15 cm. in depth;
  • often damages potatoes
  • about 15% of the crop remains under the ground
  • A single axle tractor with a fan spudger consumes a lot of fuel;
  • The harvest has to be harvested manually;
  • only able to work in light, loose soil.

KKM-3 for power tillers with PTO has a well thought-out design. The module includes a special sieve (screen) and an active ploughshare (knife). Two stable support wheels. This modification of the potato harvester has a solid height of the harvested ridge up to 17 centimeters. The gentleness of the soil separation can be regulated with the help of the engine speed of the used equipment.

Vibratory potato harvester KKM-3 for power tillers with PTO is suitable for operation on any type of soil. Even on heavy soils, the implement works smoothly, without causing any problems to the operator. It is very convenient that the dug food crop is almost completely cleared from the ground. This model is suitable for work on small and medium-sized plots. The spudder doesn’t need much fuel to operate efficiently, making it economical.

Advantages of the vibrating potato digger KKM-3 to power tillers with PTO:

Potato diggers differ in such parameters:

  • Dimensions. the greater the length and width of the working mechanism, the more productive the potato harvester is. Narrow implements are more suitable for single beds in the household, while the wider ones with a grapple are used for harvesting potatoes from more than a hectare of land.
  • How to clean the potatoes from the ground. this factor is taken into account, depending on the soil conditions in the region where the potato digger is to be used. If the loose chernozem is easy to fluff, then loamy and sandy soils need additional cleaning.
  • Operating principle. this determines how productively the attachment works.
  • The presence/absence of additional wheels. large machines must have an additional point of support, otherwise it will be difficult for the power tiller to do its main work.
  • Attachment method. the optimal option is considered a screw way to attach the potato harvester to the tiller. This allows the implement to be detached at any time. Some models are mounted only by welding.

Depending on the technological features, there are several types of potato diggers: fan, screen, drum, conveyor, conveyor, vibrating. Each of them is designed for certain types of soil and volumes of processed area.


It takes its name from the fan-shaped arrangement of the wires. Operating mechanism is in the form of a plough, with equally spaced bars radiating out from the plough.

The principle of operation is simple: the plow plunges into the ground under the influence of traction power unit potato rises from the depth and falls into the bars, where the shaken off the excess soil and lies on the carpet on the bed.

Advantages are ease of fabrication and low cost. The disadvantages are a rapid wear and tear of the wires and their breakage when used on hard ground.


Has a more complicated design with extra wheels and points of support. contains the gratings, which are tilted with respect to the ground at an angle.

The potato digger is lowered below the location of the potatoes, after which the potatoes are lifted to the surface, the excess soil on the grid is removed, and the root crop is placed on the ground surface.

One of the advantages is that you can get as much potatoes as possible clean off the ground. A disadvantage is low productivity.


It is a complex mechanism that simplifies the landowner’s work as much as possible. With the help of a plough, which is deepened into the soil layer, the potatoes are lifted and fall onto a grid, after which they are transported to a rotating drum. Next, the potatoes are further cleaned from the soil and placed in the box.

There is another principle of operation of the drum potato digger: the knife cuts the soil layer together with the potatoes and takes them into the drum, where under the influence of the constant movement the excess soil is sifted and the potatoes are poured on the ground.

The advantage is the ability to handle large areas, as well as transport the potatoes directly into the container. No need to dig potatoes up from the ground. The disadvantages include the inability to use on hard soils.


It consists of two main parts: a transporter, on which the potatoes move, and a flatbed, by means of which the layer of soil with root crops is lifted. Not suitable for wet and sticky soils.

The disadvantage is that it cannot be used on fields where there are weeds. The potato stalks get caught in the conveyor belt, wrap themselves up and slow down the potato harvester.


Potato digger is a bucket with a deepening, in the center of which a conveyor belt is installed.

Root crops are lifted with the soil, moved onto the belt, where the soil residue is removed. Then the potatoes are placed on the ground surface.

The advantage is the possibility of processing several beds at the same time. Potatoes are clean and with minimal damage.

How to mount the potato digger on the power tiller

The spudder is now ready, but it is still too early to start. First of all, it needs to be set up and aligned properly. The aim is not only to harvest the potatoes, but also not to damage them.

Walterscheid NZ Kinematics

  • Loosen the bolts between the rack and the lock.
  • Move the ploughshare, at the same time setting the furrow depth. The optimal depth is 30 cm. If the depth is less, you can damage the crop.
  • Tighten the clamping screws.
  • Now adjust the inclination of the board. All you need to do is to turn the crank until the board hits the ground, then turn it the other way. The back part of the board must be approx. 5 cm above the ground.

The simplest mechanism. This potato digger is essentially just a shovel with the edges bent inward and thin metal rods welded to it. The sharp tip digs into the ground, lifts the potatoes, the soil falls onto a grid of metal bars as it moves, the soil falls through the bars and the clean potatoes are placed on the ground where they are picked up manually.

  • Simple design, easy to build,
  • Easy to mount on a single-axle tractor,
  • Can be installed even on motor blocks with low engine power (for example, Neva MB),
  • High capacity,
  • Reliability,
  • Price.
  • Small digging depth, up to 15 cm.,
  • Small working width, up to 20 cm.,
  • Not everything can be dug, about 15% of potatoes and other root crops stay underground,
  • Damages the potatoes,
  • Only works on light soils,
  • The power tiller uses less fuel,
  • Potatoes must be hand-harvested after digging.

Harvesting on farms and small household plots as well as planting seed and seedlings is rather laborious and monotonous. And if on large farms all work is done with machines, on private plots, land cultivation, sowing and harvesting are mostly done manually. However, for such farms small agricultural machinery such as power tillers, cultivators, mini-tractors and various attachments have been developed specifically. One type of such equipment is a potato tiller for a power tiller, which allows the fastest, easiest and highest quality harvesting on a small homestead plot.
