Linkage of agricultural distribution device, designed as hydraulically operated unit of single hollow lower and single upper steering rod

摘要

The distributing device with a storage container resting on a frame (2), either pulled by a tractor or self propelled, is fitted with a new design of linkage (3), joined to the frame (2) with an oscillating and swinging suspension (5). The parallel positioned linkage (3) comprises only a single but extremely torsion resistant hollow lower (6) and a single upper steering arm (7), both operated by hydraulic cylinders (8), resulting in an efficient but compact unit (3).
