Overview
The 4UY-130 is a three-point-suspension potato harvester with a 1300 mm working width, 780 kg structure and 540 r/min PTO drive, designed to match 100–120 HP (Bridge) tractors. Its double grid-chain conveying system, 65Mn shovel blade and depth-roller limiting mechanism provide stable digging at 0–400 mm depth, with adjustable working height to suit different field conditions.
Key features
1300 mm working width
Single-pass digging width matched to 100–120 HP (Bridge) tractors for efficient potato lifting at an estimated 0.267 ha/h.
Double grid-chain conveying
Two-stage grid chain with 75/55 mm clearance separates soil progressively while transporting tubers to the rear discharge.
Depth-roller limiting
Depth-roller mechanism with 0–400 mm adjustment keeps digging depth uniform across uneven beds.
Hardened wear parts
65Mn shovel blade and 55CrSi chain bars resist abrasion in stony or clay soils for longer service life.
