摘要:
This document discloses a press wheel (161) for pick-up and/or compaction of material being fed to the ground by an agricultural implement (2). The press wheel comprises a centrally positioned hub (1611), a ground-bearing surface (1612) located at a radial distance from the hub, and a plurality of spokes (1613) extending between the hub and the ground-bearing surface. The extension (De) of each spoke between the hub and the ground-bearing surface is non-parallel to a radial direction (Rh) starting from a point at which the spoke is connected to the hub. It also relates to a row unit comprising such a press wheel and an agricultural implement comprising a number of such row units and a method of setting the hardness of a press wheel.
