This is an exact-model Hongyou product page for international agricultural machinery buyers. The current factory drawing and selected configuration should be confirmed before ordering.
The 4UD-90S is a three-point belt-conveyor potato harvester recorded in the user-supplied Hongyou table. Its 900 mm intake, ≥50 HP tractor requirement and listed belt-conveyor layout support a defined discussion about ridge fit, tractor linkage and crop discharge.
The crop path is designed to dig below the tuber zone, elevate soil and crop on the belt, and allow separation before discharge. Buyers should check soil moisture, clod strength and foliage volume because these determine whether soil clears cleanly or carries forward with the crop.

Buyer questions
What is the published working width for 4UD-90S?
The user-supplied Hongyou table lists 900 mm. Use the planted ridge and tractor wheel track to determine whether it matches the actual field.
