| 摘要 |
A rotatable flail-type agricultural implement is disclosed which includes a central axle and a plurality of radially and circumferentially spaced, flexible, hammer-supporting chains presenting a plurality of ground crop-engaging flails upon rotation of the axle. The axle is preferably composed of a pair of elongated, telescopically interfitted sections, at least one of which is shiftable, such that the effective width of the implement can be varied to accommodate different crop row spacings. In addition, the axle sections include complemental, spiral key and keyway structure for maintaining the flexible hammer chains in a substantially constant, spaced relationship to the central axle, irrespective of variances in the axle length. A V-shaped assembly for mounting the flails on the front of a mobile tractor is also disclosed and includes a pair of diverging arms each including telescopically interfitted sections, such that the transverse or lateral distance between corresponding flails on the separate arms can be varied.
