The potato digger is an agricultural machinery which can be towed by a tractor or connected to it via a three-point hitch; tractor-mounted potato diggers are used to dig potatoes out of the ground for harvesting.
Their large ploughshare, which covers most of the small size of the machinery, allows them to enter the soil, convey the product to the chute grate at the back of the machine and separate it from the soil by means of the oscillating sieve.
For the crop to be preserved for a long time, the potatoes must be dug carefully, avoiding damage such as cuts or dents.
Potato diggers can be divided into two groups:
The first type is characterised by the presence of a row of blades on the ploughshare that pull the tubers out of the ground, while the second type has a more complex structure as it features two rows of conveyor bars with ridges.
The use of a tractor-mounted potato digger, whether single row or two-row, is determined in relation to the size of the areas to be worked and consequently in proportion to the amount of product to be dug out.
The potato digger can also be used to extract onions or garlic. In fact, the ploughshare penetrates the soil while the vibrating movement activated by the tractor's PTO facilitates the harvesting and cleaning of tubers and bulbs. This machine is designed to make the harvesting of tubers and other crops easy and above all fast, as the machine only needs to pass once over the area to be worked for complete harvesting.
It is a tool suitable for both flat and sloping areas, with a variable digging depth, perfect for all types of soil.
The vibrating models provide for the digging out of more than 98% of the potatoes, increasing the productivity of the harvest. Operation is performed by a vibrating sieve, which removes soil residues left over from the extraction.
The “universal” models guarantee 85% efficiency, but their great advantage lies in their value for money.
This is due to its simplicity of construction. In fact, the operation of this model is very similar to that of a simple rake, and there is no need for connection to the tr-actor's power take-off.
Finally, models with a conveyor belt are equipped with a belt system, where the harvested tubers slide, and which enables the removal of residual soil very effectively
