4UY-90 belongs to a published Hongyou 4UY potato harvester family table. The table lists a 900 mm working width, 560 kg overall weight and 70–100 HP supporting power for this particular suffix. The family is described with three-point suspension, 540 r/min output-shaft speed, 65Mn blade, depth roller and double grid-chain conveyor.
The published 0–400 mm digging-depth adjustment range should be set from the actual crop zone rather than used as a standard operating depth. The listed efficiency is a manufacturer figure and will change with soil condition, ridge geometry, crop density, forward speed and operator setup.
