A professional potato digger for a walk-behind tractor is very expensive. Due to difficulties with the harvesting process, land owners are constantly inventing any methods to facilitate work. A budget option is to make a homemade potato digger for a walk-behind tractor or tractor.
What is a potato digger for a tractor? This is a functional device that allows you to separate the tubers of the vegetable crop from the ground. As a result of the mechanism, the root crop enters the soil surface. The cost of finished mechanisms is very high. When planning the manufacture of the device with your own hands, it must be taken into account that all designs can be divided into the following types:
A rumble digger includes a ploughshare, drive and barrel. The performance of such mechanisms is considered high. The operation of a vibrating potato digger for a walk-behind tractor takes place in the following order:
- picking up the earth and its submission to a special table;
- soil spillage through cracks under the influence of a vibrating table;
- rash of tubers from the opposite side onto the soil.
The potato remains to be raised to put it in a special container. Transporter potato digger is a more complex unit than a screening one. It consists of a belt, drum and conveyor.
A universal digger, which is a single-row fan-type mechanism, must be attached to a walk-behind tractor. Different nozzles can be attached to it, which allow for some types of agricultural work:
- tuber planting;
- virgin land;
- hilling plants;
- sorting and harvesting vegetables in the fall.
Home-made potato digger for walk-behind tractor provides automation of the whole process of harvesting potatoes. This greatly facilitates the implementation of agricultural work.
How to make a potato digger for a walk-behind tractor
Potato digger working principle
A potato digger for a do-it-yourself walk-behind tractor made in accordance with the drawings must have certain characteristics. If it is a manual potato digger, then it must have an appropriate drive. Before carrying out the work, you should calculate the budget of the event and determine the method of cultivating the land by the unit.
A do-it-yourself potato digger made for work on a land plot has a simple principle. The design includes 2 steel knives necessary for cutting the ground. Tubers collected with knives, together with soil, enter a hopper for collecting vegetables along a special transport grate.
A vibrating potato digger separates the tubers from the soil during operation. You can dump your crop on the ground next to the unit if the bunker was not equipped with special material. The individual structural elements of metal can be connected in 2 ways:
- based on electric or gas contact welding;
- fasteners (bolts, nuts, locknuts).
These methods provide a strong connection of metal parts. Bolted joints have various advantages over welds since a potato digger can be easily dismantled if necessary.
To connect the individual parts, you do not need to waste time working with a special tool. It is necessary to prepare only a drill with a drill and a pair of keys. Homemade potato diggers are made from a metal sheet 5-7 mm thick. It is these dimensions that can guarantee a high level of strength of the entire structure.
A potato digger for a mini tractor does not have too much weight, which greatly facilitates the digging of the soil. For work with solid soils, a digger with a larger size should be used. It is heavier, so the ploughshare cuts into the soil better and turns out a layer of soil with vegetable tubers.

Device Assembly Steps
Before making a potato digger with your own hands, you should familiarize yourself with the manufacturing technology of this unit. It includes the following main steps:
- assembly of a frame from metal corners and channels;
- fastening to the prepared metal frame of the elevator and other elements;
- mounting on the elevator shafts transmitting force from the rotation of the wheels;
- installation on the frame of durable metal sides;
- installation of a lattice vibrating due to rotation of the wheels;
- fastening a metal share to the elevator with 10 mm bolts;
- assembly of the support and transport unit;
- connecting the unit to agricultural machinery, for example, MTZ.
A home-made potato digger of a screen type must be assembled using a welding machine or bolted from metal corners. The greater the load will be on them, the more should be provided for the thickness of the material. Often they use corners with overall dimensions of 63x40 mm.
Do-it-yourself potato digger is made using an iron channel. The scheme of bolted connections requires the purchase of hardware in the required quantity. The drawings involve the use of a chain that transmits torque to the wheels of rubber or metal.
The ploughshare is only strengthened after the final assembly of the elevator and fixing it on the supporting frame of the digger for the walk-behind tractor. It is a direct working part, representing a plow that is needed so that you can easily turn a potato root crop out of the ground. The support and transport unit made of disks or wheels also includes 2 roller chains. It is made using a metal rod.
Particular attention in the process of assembly of the mechanism must be paid to how a screening potato digger joins a walk-behind tractor after assembly. This stage is the last in the process of manufacturing the unit on a walk-behind tractor. If the structure is poorly fixed on it, then it will be necessary to review not the attachments, but the walk-behind tractor itself.
