DIY potato planter and potato digger for walk-behind tractor

Recommendation points



If you occupy large areas on your site for potatoes, then the help of various devices will probably not be superfluous. You can make a potato planter and potato digger with your own hands, and we have prepared drawings and recommendations for their assembly for you.

Planting and harvesting potatoes is hard work, especially if you have to cultivate a large area. If you already have a walk-behind tractor, then you can buy or make on your own devices that mechanize these operations, which significantly speeds up the process, increases productivity and even the quality of planting tubers and harvesting.

Self-made potato planters

An integrated potato planter must solve several problems at once:

  • the formation of an even furrow of the required depth;
  • uniform supply of tubers;
  • filling furrows with soil.

Therefore, the unit consists of several units: furrow cutter, tuber, burying discs.

The tuber is one of the most difficult units of the unit and not all home craftsmen manage to repeat the factory mechanisms on their own. Some farmers even advise, instead of installing a mechanized tubing, to plant an assistant on the frame next to the container with planting material, who will manually throw the tubers into the furrow, which is cut and buried by the mechanism of the mounted simplified potato planter.

And yet there are designs that you can make yourself. Below are the drawings that you can use to assemble the potato planter yourself.

Another design is an automatic potato planter. It is a frame assembled from channels No. 8 with a plywood or metal hopper with a capacity for 2 buckets of potatoes, which is equipped with a feed lift. The lift is assembled from special cups that move with the chain. The movement is given to it from the drive wheel. Masters recommend taking a bicycle chain for transmission, an asterisk on a planter with O 80 mm, and on a walk-behind tractor – O 160 mm. A tubular pipe is attached under the elevator.

How to make a potato planter with your own hands according to factory drawings

Drawings of a factory planter designed for a heavy walk-behind tractor with ballast in the front or a mini tractor. All elements are attached to the frame.

Here, the ripper is a cultivator share assembled with a tine. The seatpost is made from a 42×3 mm tube, the seatpost supports are made from a corner of 50x50x5 mm, the footrests are made from 6 mm sheet. These parts are made separately and welded at a level that is convenient for a particular person..

Covering discs are mounted on a support, while the angle of attack and the degree of penetration are regulated by ladders (see drawing) and bushings (4 pcs. Per one axis).

The depth of the furrow cutter is adjustable on the frame and rigidly fixed with stepladders. Tuber feeding into the planter – by lift type (see above) or manual.

For mulching planting, rippers are used, which are cultivator nozzles attached to a holder – a rack, mounted on the bottom of the frame. The depth of their impact on the soil is regulated by the vertical movement of the racks and fixed with through fingers.

The wheel axle is also bolted to the frame. This is an assembly unit and it is quite difficult to make it – here both machining and welding, and precision is needed, so it is better to order the manufacture of a part according to a drawing in a workshop or use, if possible, used rubber wheels or others that do little damage to the soil.

Self-made potato diggers

There are three main designs of potato diggers:

  1. Vibrating or screening type. These are high-performance attachments consisting of a vibration shaft, a share and a vibration drive. Principle of operation: potatoes are captured together with the soil, moved to a vibrating table, where the earth wakes up and the tubers are poured along the row.
  2. Conveyor type. Complex units, consisting of a shovel-like share, a cleaner drum and a chain-bar conveyor.
  3. Arrow type. The simplest design, which is a “fan” attached to the walk-behind tractor with a single hitch, through which the earth wakes up, and the potatoes are thrown to the sides.

For the elements of the potato digger, you need to take a sufficiently thick metal, given the resistance of the soil. The “heavier” the soil, the thicker should be the metal in contact with it.

Pointed Potato Digger

This is the simplest design, and, nevertheless, quite productive. In self-production of the device, a drawing of the product and a useful video on the topic will help, in which the wizard shows all the stages of assembly.

The bipod can be taken from a serial cultivator, the bar can be made from a steel corner 50×50 mm. The tip is the trimmed tine of the cultivator, and the shaker teeth can be made from old forks by cutting at 45 ° and welded to the tip with the trimmed part.
