Fan potato digger for power tiller with your own hands

How to make a Dolphin potato digger by yourself

Such devices are quite simple. You can make an active Dolphin potato digger with their own hands. To do this, you need to have the following tools: welding machine, angle grinder, drill, bolts and drills on metal.

  • Sheets of steel, 3-4 mm thick, for the ploughshare;
  • thick steel plate or rectangular profile for holder and bracket;
  • rebar. 8-10 mm, not corrugated;
  • bolts with a diameter of more than 10 mm.

Dolphin potato harvester with their own hands

The process of making a Dolphin potato harvester is as follows:

  • Two holes are drilled in the ploughshare so that it can be attached to the stand.
  • Measured parts of steel rod, 47-50 cm long, should be welded to the plough, in its extended part, which should diverge like a fan.
  • A rack-holder is attached to the ploughshare by bolts or by welding.
  • A bracket is welded on top of the stand. There should already be holes in it so that the single axle tractor and potato digger can be attached together.
  • To strengthen the construction, a metal strip is welded to the plough in the lower part.

The potato digger active Dolphin with an active blade is fitted with an additional vibrating nozzle, which is attached between the bars, just in the middle.

All self-made potato diggers should be used on small plots. Experience of many gardeners and vegetable growers clearly demonstrate their practicality and efficiency. For industrial use (processing of large agricultural land) use factory-made devices, according to technical requirements and standards.

Detailed drawings of the fan type potato digger for power tillers photo and video of the device in work.

As is known, there are two types of potato diggers for motor blocks, fan and vibrating, the most simple in the manufacture of fan type digger, and its device we will consider.

Fan digger is the hinged equipment, in this variant for the power tiller, this is how this device looks like.

The device for digging potatoes is a plough with a fan of rods, while moving power tiller plows into the soil and lifts it on a grid of rods, in turn rods loosen and sift the soil, while potato tubers are thrown already on top of the soil.

The video shows the working principle of a fan potato digger.

To make a potato harvester for your power tiller, you can use the following drawings with dimensions and photos.

Among the disadvantages of potato diggers for power tillers is a fairly high loss of root crops. The sharp tines of the machine can damage the crop. It is generally estimated that about 20% of all harvested fruit can be ruined by the machine.

How to make a conveyor belt spudder for a power tiller with your own hands

The conveyor potato harvester can also often be called a belt harvester. This is due to the design of the device. Ribbon potato digger for power tiller with their own hands is made according to the following plan:

  • First of all the gearbox has to be assembled. It consists of the body, two shafts and gears. The device can be borrowed from any unwanted or used machinery.
  • Next, you need to make the belt conveyor which transports the fruit on the belt. It can be assembled from metal rods and a chain made of links. With its help, the construction will be set in motion.
  • A shaft is attached to the front of the design, and there are three hubs on it. two on the edges and one in the middle.
  • Install a second shaft in the rear. On it also attach the sprockets, in the number of two pieces. The total length of the conveyor belt should be 50-70 cm.
  • Mount the parts on a frame made of sheet metal and uprights. Fix wheels to the structure.
  • Use leaf springs to construct a pruning blade that will bring the earth with the fruit to the transporter.
  • The design is chain-driven from a bicycle, so depending on the size of the sprockets you can adjust the speed of the conveyor.


Transporter (conveyor) potato diggers are made both large and quite miniature. Potatoes and subsoil are loosened with a plough knife. The cut material is fed onto the conveyor belt and separated.

The belt is a lattice made of metal rods or pipes, arranged in parallel to each other. They are fixed in the moving rim of the conveyor (chain). Conveyor belts are also made of steel mesh and rubber on a fabric base. Soil is poured down through the grating or openings, and the potatoes are moved into the arable or receiving hopper.

There are many designs of conveyor potato diggers, each master introduces new elements and improvements to the products. The process of making a conveyor digger includes the following steps.

  • Welding frame (carcass) made of square steel sections and angles.
  • Making a plough blade out of sheet steel.
  • Installation of conveyor belt rollers or wheels into the frame.
  • Assembling a conveyor belt from chain, steel bars, other material.
  • Mounting brackets and fasteners for gearbox and pinion.
  • Installation of conveyor belt and mechanisms in the frame.
  • Installation on the frame of the blade (plowshares) and the wheels.

Potato digger application

A device for digging potatoes. a type of attachment. It is attached to a power tiller or fixed with a trailed device. Purpose. to speed up harvesting. With the potato puller it is possible to pick up tubers on an area of 0.1-0.2 ha in 1 hour.

On small and medium-sized areas it is easy to dig potatoes with a power tiller

Drawings, diagrams, dimensions of potato harvesters for power tillers Neva, Mole, Kaskad, MTZ-09H, Salut, Agat

The most popular among farmers and landowners is considered to be the single-axle tractor “Neva”. It has a user-friendly design and powerful technical features. The most suitable homemade potato harvester for the “Neva” power tiller is a screen-type device.

Due to the specificity of its work, the screen potato digger for the “Neva” power tiller is called the vibrating one

Universal option for all types of power tillers. “Poltavchanka” model potato harvester. The parameters of such a device are 950×790×800 mm, the processing depth. 25 cm. These characteristics allow the unit to be used in any conditions, regardless of soil and type of crops. “Poltavchanka” is valued for high productivity in a relatively small size.

“Poltavchanka” is popular with owners of power tillers “Mole” and “Agat”

The “Salut” and “MTZ-09H” power tillers are similar in their construction, that’s why the identical drawings are often used for the production of potato harvesters for this equipment. Digging tools for these devices have the same mounting system, which allows to use the same tool for both models.

“Salut” and “MTZ-09H” have an original design, so the drawing of the potato digger for these devices has different features

A vibratory potato digger is also recommended for the Cascade power tiller, but because of the more massive wheels, the harvesting device may have different parameters from similar equipment.

Often, when making a vibratory digger for a Cascade power tiller, changes are made in the plowshare arrangement and wheel size
