Tractor-mounted Potato Diggers – Vibrating Sieves and Sifting Conveyor

The potato digger is an agricultural machine towed by a tractor or carried by a three-point hitch;the tractor potato plough is used to dig potatoes out of the ground for harvesting.

Its wide ploughshare, which covers most of its small size, allows it to enter the ground, conveying the product onto the sieves, which separate it thanks to the oscillating grid.

In order for the harvest to be preserved for a long time, the potatoes must be dug up carefully, avoiding damage such as cuts or bruises.

The potato digger can also be used to extract onions or garlic. It penetrates the ground and, through the vibrating movement powered by the tractor's power take-off, facilitates the harvesting and cleaning of the tubers. Ultimately, this machine is designed to make the work simple and immediate, as a single pass is enough to completely harvest the worked area.

It is a tool suitable for working on both flat and sloping ground, with a variable digging depth, perfect for all types of soil.

there are different types of tractor-mounted potato diggers, each with specific characteristics that make them suitable for different agricultural needs.

• Frame potato diggers: Simple and sturdy machines ideal for small plots of land and non-intensive farming.
• Rear discharge vibrating potato diggers: Equipped with a vibrating system that facilitates the separation of soil from tubers by discharging the tubers at the rear of the machine.
• Side-discharge vibrating potato diggers: Similar to the rear-discharge versions but with side discharge, ideal for working in confined spaces.
• Professional belt potato harvesters: Designed for intensive use, these machines are equipped with a conveyor belt that ensures high productivity and excellent separation of the tubers from the soil.

Tractor potato harvesters are essential tools in agriculture for efficient potato harvesting. These machines are used to separate potatoes from the soil, reducing manual labour and significantly speeding up the harvesting process. The use of potato harvesters is particularly advantageous in medium and large-scale crops where manual harvesting would be extremely time-consuming and resource-intensive.

• Automated harvesting: Potato harvesters automate the separation of tubers from the soil, ensuring fast and accurate harvesting.
• Reduced tuber damage: The machines are designed to minimise damage to the tubers during harvesting, preserving the quality of the final product.
• Adaptability to different soil types: With a choice of working widths and discharge types, potato harvesters can be used on a variety of soils, from light to more compact soils.
• Professional and hobby use: While professional belt models are ideal for large farms, simpler models such as frame potato diggers are also suitable for farmers with more modest needs.

It should also be noted that tractor-mounted potato diggers can also be used to extract onions or garlic from the ground. Tractor-mounted potato harvesters are therefore essential for both large farms and those who manage smaller crops, always ensuring efficient and high-quality work.

Tractor-mounted potato harvesters are sturdy agricultural machines designed to withstand demanding working conditions and optimise potato harvesting. Each component is designed to ensure efficiency, durability and reduced damage to the tubers during harvesting.

• Frame: The frame is the supporting element of the machine, usually made of steel to ensure maximum strength and durability. The frame supports all components and must be able to withstand continuous stress during use.
• Vibration system: In vibrating models, the vibration system facilitates the separation of the tubers from the soil. This mechanism, driven by the tractor-mounted power take-off, causes a vibrating movement that helps to detach the soil from the potatoes, making harvesting more efficient.
• Discharge system: Potato harvesters can have rear or side discharge. Rear discharge is suitable for working on large surfaces where the tubers can be easily collected behind the machine. Side discharge, on the other hand, is ideal for working in confined spaces, allowing the rows to be kept tidy and facilitating harvesting.
• Conveyor belt: Professional belt models include a conveyor belt that facilitates the transfer of tubers from the collection point to the discharge system. This component is essential for large-scale operations, improving the speed and accuracy of harvesting.
• Single row and double row: Single row potato diggers feature a single row of tines or poles that extract the tubers from the ground. They are ideal for operations on medium or small surfaces. Double row potato diggers, on the other hand, have two rows of poles and are more complex. The latter are suitable for large-scale operations where greater efficiency in terms of the quantity of product extracted is required.

Tractor-mounted potato harvesters work by harnessing the power of the tractor itself via the power take-off (PTO) shaft to power the vibration and digging system.

• Connection to the tractor: The potato digger is tractor-mounted via the three-point hitch. This stable and secure connection is essential to ensure that the machine works in synergy with the tractor, allowing for precise control and smooth movement.
• Activation of the vibration system: Once connected, the tractor's power take-off transmits the power needed to activate the potato digger's vibration system. This system is crucial to the machine's operation, as the vibrations facilitate the separation of the soil from the tubers, reducing the manual labour required and improving harvesting efficiency.
• Penetration into the soil: The machine is equipped with tines or blades that penetrate the soil, lifting it and separating it from the potatoes. In single-row models, a single row of tines performs this function, while in double-row models, two rows of tines or poles work simultaneously, increasing harvesting capacity.
• Movement of potatoes to the discharge system: The vibrating movement of the machine pushes the tubers towards the discharge system. Depending on the model, the discharge can be rear or side. In professional belt models, a conveyor belt carries the tubers from the digging point to the exit, ensuring effective and orderly separation of the product.
• Discharge and collection: The potatoes are discharged behind or to the side of the machine, ready to be collected manually or by other automated collection systems. The choice of discharge type depends on the operator's needs and the specific conditions of the field. The discharge system is designed to minimise damage to the tubers, preserving their quality.

Tractor-mounted potato harvesters are divided into different types, each designed to meet specific operational requirements and working conditions. Here are the main ones:

• Frame potato harvesters;
• Rear-discharge vibrating potato harvesters;
• Side-discharge vibrating potato harvesters;
• Professional belt potato harvesters.

The vibrating models allow for the extraction of over 98% of the tubers, increasing harvest productivity. They operate thanks to a vibrating table, which removes any soil residue left over from digging.

The "universal" models offer 85% efficiency , but their great advantage lies in their low prices. This is thanks to their simple design. The operation of this model is very similar to that of a rake, and it does not need to be connected to the tractor-mounted power take-off.

Finally, there is the conveyor model, which is equipped with a belt system that the tubers pass through, allowing for very effective removal of residual soil.

Frame potato diggers are one of the simplest and most sturdy types available on the market. These machines are characterised by a basic but extremely resistant steel structure, which guarantees longevity and reliability over time. Frame potato harvesters are ideal for farmers who work on small surfaces or who need equipment that is economical and easy to maintain.

Tractor potato harvesters are equipped with various technical features that determine their effectiveness and adaptability to different working conditions. These aspects are essential to ensure that the machine meets the specific needs of farmers. The main technical features include the following:

• Discharge system: Determines the direction in which the tubers are deposited after being extracted from the ground, affecting the ease and efficiency of harvesting.
• Working width: Indicates the width of land that the machine can work in a single pass, a key factor in determining the productivity of the machinery.

The discharge system is one of the most important technical features of tractor-mounted potato harvesters, as it directly affects the management and efficiency of harvesting. There are two main types of discharge: rear discharge and side discharge, each with its own operational advantages.

• Rear discharge: In this system, the tubers are deposited directly behind the machine. This configuration is particularly suitable for working on large surfaces where a linear and orderly harvesting system is required. Rear discharge is ideal for open terrain, as it allows continuous working without having to frequently interrupt the operation to adjust the direction of the harvest.
• Side discharge: This system allows the tubers to be discharged to the side of the machine. It is particularly useful in narrower fields or in situations where it is necessary to keep the rows of tubers separate and orderly. Side discharge is preferable when manoeuvring space is limited or when it is important to avoid repeatedly passing over already worked soil, thus minimising soil compaction.

Working width is one of the most important technical characteristics of tractor potato diggers, as it determines the amount of soil that can be worked in a single pass. This measurement directly affects the productivity of the machine and the speed at which harvesting can be completed. The potato diggers available on the market offer a range of working widths that can vary from 45 to 140 cm, allowing you to choose the solution best suited to the specific needs of the soil and the operator.

• Reduced working width (45-80 cm): Potato diggers with a smaller working width are ideal for small plots of land or situations where precision is essential. These models are perfect for farmers who manage limited surfaces or those who have to operate in confined spaces where it is necessary to avoid damaging surrounding crops.
• Medium working width (80-120 cm): A medium working width is a good compromise between productivity and manoeuvrability. These potato diggers are suitable for medium-sized farms, where the ability to cover a good area in a reasonable amount of time is important, but where a certain level of precision is still required.
• Wide working width (120-140 cm): Models with a larger working width are designed for large-scale operations, where harvesting speed is crucial. These potato ridgers are ideal for large farms that need to cover significant areas of land in a short time. The greater width allows a higher volume of potatoes to be harvested in a single pass, increasing daily productivity.

Choosing the right tractor potato harvester can make a big difference in terms of efficiency and quality of agricultural work. There are several factors to consider before making a purchase, including:

• Field size: The size of the area to be worked is one of the first factors to consider. For small plots, a model with a narrow working width, such as a frame potato digger, may be sufficient. For larger surfaces, it is preferable to opt for models with a greater working width, such as vibrating or professional belt potato diggers, which allow you to complete the job more quickly.
• Type of soil: The composition of the soil can influence the choice of potato digger. Soft, obstacle-free soils can be easily worked with any model, while more compact or stony soils may require more sturdy and powerful machinery, equipped with vibration systems that facilitate the separation of the tubers from the soil.
• Intensity of use: If the potato harvester is to be used for large-scale production or professional use, it is advisable to choose more advanced models, such as belt-type harvesters, which offer greater productivity and durability. For less intensive use or small crops, a simpler and less expensive model may be sufficient.
• Type of discharge: The choice between rear and side discharge depends on the configuration of the field and operational preferences. Rear discharge is ideal for large areas, while side discharge is more suitable for confined spaces or where precise organisation of the harvest is required.
• Available budget: Cost is naturally a decisive factor. Frame potato diggers are the most economical option, while professional belt models require a greater investment, justified by their high productivity and durability.
