摘要

The cultivator frame (2) has pref. two rows of tines with shares, while a unit (11) of hollow disc (12, 13) and a roller tiller (14) follows the cultivator. The unit is height-adjustable parallel to the cultivator frame by a four-link linkage, whose links engage a base (16) and a coupling plane (19). The base and coupling planes are approx. horizontal, and the unit of hollow discs and the roller tiller is allocated to the coupling plane. The hollow discs depth is adjustable wrt. the coupling link (20). Pref. they can be adjusted in groups, individually, or all together. USE/ADVANTAGE - For mechanised hoes, harrow etc., with simple design and easy handling, without need for adjustment of the tines.
