Closed device combination

摘要

Closed device combination, consisting of a soil tilling device, in particular a soil tilling device driven by power take-off shaft, a trailing roller arranged downstream of the soil tilling device, it being possible for the trailing roller to be of various types of design, and a semimounted seed drill, the portioning members of which are driven by at least one drive wheel which is arranged on the seed drill and designed in particular as a strake wheel. In order considerably to improve the generic closed device combination and to develop it advantageously for proper use on all soil types occurring, it is envisaged that the drive wheel (10) is arranged on a support arm (11), that the support arm (11) is connected to the frame (13) of the seed drill (3) and that the support arm (11) is designed as a rocker (12) and the drive wheel as a support wheel (10) (Fig. 1). <IMAGE>
