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 4UC-70 is a compact Hongyou potato harvester record with a published 700 mm working width and 95 kg weight. It is described as a hand-type / trail-type layout with a moving blade and depth roller. Its low listed supporting power threshold of at least 20 HP makes it a separate choice from the 70 HP class mounted models.
The published depth adjustment is 0–250 mm. Before selecting the machine, match this adjustment to the crop’s actual depth and the tractor’s available PTO arrangement. The theoretical efficiency listed online should be treated as a manufacturer listing, not a guarantee for a specific soil or field shape.
