Powered cultivator with follower roller - has coupling between main frame and tractor bottom linkage allowing independent movement of cultivator unit

摘要

The agricultural implement consists of a driven harrow, whose main frame has a top and two bottom linkages for coupling to the three point linkage of a tractor. An additional implement follows the harrow. A couple (54) is provided between the harrow main frame (19) and the bottom linkage (48). Between the harrow main frame (19) and the couple (54) is a linkage connection (56), which allows horizontal swing movements of the harrow. The additional implement is in the form of a harrow (18) and its fixing poles (66, 72) are connected directly with the three point coupling linkage. The top fixing part (72) of the roller (18) and the top linkage (73) of the main frame (19) are connected by an adjustable coupling mechanism (61).
