The 4U-120D Potato harvester is a specialized, tractor-mounted potato harvesting solution engineered for high-performance yields. Designed to bridge the gap between small-scale manual harvesting and expensive self-propelled harvesters, the 4U-120D offers a 1200mm working width, making it the ideal choice for medium-to-large-scale agricultural operations. It excels in diverse soil conditions, ensuring that your harvest is fast, clean, and damage-free.
Unlike traditional fixed shovels that increase tractor drag, the 4U-120D features a vibrating flat shovel.
Advantage: The vibration breaks up the soil crust before the tubers reach the conveyor, reducing the "soil load" and allowing the tractor to operate at a higher gear, saving up to 15% in fuel costs.
The conveyor system uses a reinforced grid-sieve design made from high-tensile carbon steel.
Function: As the potatoes travel up the $2550 \text{ mm}$ frame, the sieve filters out clods, stones, and haulm (vines).
Crop Protection: The bars of the sieve are often coated or spaced precisely to ensure that even thin-skinned "new potatoes" are not bruised or peeled during the transition.
Equipped with independent depth-limiting wheels, the operator can maintain a consistent digging depth even on uneven terrain.
Benefit: This prevents the shovel from going too deep (which wastes energy) or too shallow (which cuts the potatoes).
Designed with a standard 6-tooth or 8-tooth PTO spline and a Category II three-point hitch. It is compatible with a wide range of tractor brands, including John Deere, Massey Ferguson, Kubota, and local tractor models in regions like Bulgaria, Russia, and the Middle East.
The 4U-120D is not just a potato harvester; it is a multi-crop recovery machine:
Potatoes: Ideal for both starch potatoes and table potatoes.
Garlic & Onions: The flat shovel design is perfect for lifting bulbs without damaging the roots.
Sweet Potatoes & Cassava: Handles larger tubers with ease due to the wide $1200 \text{ mm}$ throat.
Medicinal Herbs: Suitable for harvesting root-based traditional medicines (e.g., Ginseng or Licorice) in sandy soils.
To ensure long-term ROI for our clients, the 4U-120D includes:
Self-Lubricating Bearings: Reduced maintenance intervals for the main drive shaft.
Replaceable Shovel Tips: The digging shovel is modular; when it wears down after hundreds of acres, you only replace the tips, not the entire assembly.
Anti-Corrosion Treatment: All steel components undergo a multi-stage painting process (Primer + Topcoat) to prevent rust in damp soil conditions.
Packaging: Compact knockdown (CKD) or semi-knockdown (SKD) packaging available to maximize container space.
Container Loading: Approximately 8-12 units can fit into a 40ft HQ container, significantly lowering the per-unit sea freight for distributors.
Lead Time: Standard production cycle is 15-20 days; we support custom OEM branding for large orders.
