Potato digger with motoblock Neva
To facilitate work in the garden, many brands of walk-behind tractors are used. The most popular are Neva, Centaur and Oka. The devices are universal: they are used to perform most of the operations related to caring for vegetables. The potato digger for the Neva walk-behind tractor makes the harvesting process much easier.

The principle of operation of the device
The use of potato diggers for the Neva walk-behind tractor in medium-sized vegetable gardens is better suited than processing with heavy equipment. Tractors have low productivity in small areas due to their size and low maneuverability.
Manual labor in medium-sized areas is also ineffective: it requires too much human energy. The best option is the Neva walk-behind tractor. The unit consumes fuel economically, is maneuverable and versatile.
Using potato diggers
When harvesting for the Neva, a potato digger is installed. The principle of operation of the device is to cut the potato with teeth and pull it out to the surface, where it is scattered to the sides. The crops are harvested from the ground by hand.
Types of potato digger:
- Plain. Outwardly, the mechanism resembles a bent shovel or paw, to the top of which rods with a centimeter diameter are attached. The sharp part buries itself in the ground and directs the potato onto the twigs, which bring it to the surface. In the absence of excess moisture, the soil flies off the fruits, and all that remains is to collect them.
- Roaring. The vibration-type potato digger works on a similar principle, but has a more complex design. Fruit pruning is performed by a ploughshare. The cut potatoes are placed on a vibrating grate, where excess soil is removed from them.
- Conveyor. It works in the same way as a vibrating one, but instead of a grate, a conveyor table is installed, which cleans the tubers from adhering soil.
Characteristics
A simple potato digger consists of:
- frames;
- working body;
- wheels;
- pulley;
- tensioner.
Additionally installed on screening and conveyor systems:
- vibrating grate or conveyor table;
- clutch unit;
- eccentric.
The advantage of a simple potato digger for a walk-behind tractor is economy and ease of use. Rumbling tools are more advanced and work faster, but their disadvantage is the complexity of the device and the high cost. The price of such devices is several times higher than the simple ones.
The choice of which potato digger is better should be based on the characteristics of the site. Rumbling do not tolerate heavy soils, but are more productive in large areas. Simple ones are suitable for all types of soil, but it is rational to use them in small gardens.
Classification
Potato diggers differ in parameters
Potato diggers for the Neva walk-behind tractor are characterized by a number of parameters:
- capture width;
- depth of processing;
- productivity;
- dimensions;
- weight;
- the number of simultaneously processed rows;
- working speed;
- productivity.
Popular models
Motoblocks Neva are supplemented with potato planters of the following models:
- KKM-1. Rumbling potato digger, which is also used when harvesting other root crops. It has a mechanism for adjusting the working depth up to 20 cm and the degree of separation by changing the speed of the walk-behind tractor. Suitable for light to medium soils. Working speed - 1.5 km / h. Processing width - 40 cm.
- KVM-3. Treat rumbling. It is possible to install an additional working body to enhance vibration. Suitable for heavy, damp soils. Technical characteristics are similar to KKM-1.
- Poltava woman. Vibrating potato digger designed for light to medium soils. The advantage is the high working speed. The device works effectively at 3 km / h. The working width is 40 cm and the working depth is 18 cm.
- Neva. The device was created specifically for Neva walk-behind tractors and has a specific type of attachment. Be of the vibration type. Capture width - 36 cm, working speed - 2 km / h. Differs in good productivity of 0.18 ha / h.
- CT-51. Conveyor potato digger with the ability to adjust the depth of work, change the angle of inclination using support wheels. Capture width - 46 cm.
Self-made potato digger
Potato diggers for a walk-behind tractor like KKM-1 have a high price. If you have the necessary tools and skills, the unit is made independently.
The advantages of this method are the price and individual selection of segments for the characteristics of the site and soil. There is also the possibility of manufacturing, based on your own preferences, which improves the comfort during processing.
For the manufacture of a screening unit, you need:
- diagram or drawing;
- parts for the undercarriage;
- frame;
- hanging segments;
- vertical adjustment rod;
- grinder with a disc for metal;
- welding machine.
Manufacturing sequence
Stages of assembling a screening potato digger:
- Assembling the base. The frame is the basis of the potato planter. It is made from centimeter or inch metal pipes. They are cut into several pieces and welded into the required shape.
- Installation of jumpers. They are designed to be fitted with a vertical control rod. The jumpers are placed on the side opposite to the wheels, at a short distance from the edge.
- Installation of racks. On the side of the jumpers, 2 metal plates of a square or rectangular shape are mounted. Vertical racks are attached to them and interconnected with a separate jumper.
- Installation of the working body. It is made from a metal plate, bending it into the desired shape. The organ is mounted on racks.
- Lattice making. They are based on metal rods. One side is welded to the working body, and the other is left free.
- Installation of the chassis and controls. Wheels and adjusting rods are attached to the holes in the frame.
Conclusion
Using a potato digger with a Neva walk-behind tractor allows you to get a crop quickly without damaging the fruits. Also, the walk-behind tractor is suitable for planting, hilling and weeding.
To obtain a good harvest, the condition of the row spacings is monitored. Weeds are regularly destroyed: they carry many diseases and impair the nutrition of potatoes.
