| 摘要 | A press ring assembly for an agricultural machine comprises an axle (70) and two opposing dish-like members (78, 80) each having a substantially circular base (88) and an outwardly curving peripheral wall (90). The wall (90) comprises a wall portion extending radially and axially out from the base and a ground cutting rim portion extending substantially radially out from the wall portion, the wall portion and rim portion defining, in section, a continuous curve. The dish-like members (78, 80) are located such that the outer edges of the respective peripheral walls (90) are adjacent and the members together define a hollow disc with a radially extending, ground cutting peripheral rim and a soil compressing, crack propagating tapered peripheral wall. The dish-like members (78, 80) are arranged on the axle (70) clamped together by means of a compressive axial load. The members comprise a resiliently deformable material so as to deflect towards one another under the compressive axial load. | ||||||
