Agricultural tool with folding frame, has tool implement turning bar connected to link arm via coupling device

摘要

The link arm is connected to the turning bar for the tool implements via a coupling device. The tool has a middle section and at least one outer wing section comprising two or more sub-sections (8b) provided with agricultural implements (16). The sub-sections can be moved relative to each other by a hydraulic cylinder unit (24) connected to a first sub-section at one end and to a turning bar (20) at the other end via a link arm (28). The bar is fixed to at least one connecting part (30) pivotally joined to the first sub-section and to a second sub-section so that the bar can be moved in order to move the two sub-sections relative to each other.
