Parallelogram guided coulter suspension with integrated vertical axis of rotation between parallelogram and coulter holder with mechanical overload protection and with at least one progressive, one fixed and at least one degressive mechanical coulter pressure adjustment with pressure roller depth guide on the coulter holder

摘要

The development presented here shows that there are significant improvements in the Scharführung in the Schartechnik seeding. For every condition on the field, any coulter pressure can be realized. From a decreasing, degressive coulter pressure adjustment to a progressive coulter pressure adjustment with new lever. An overload protection in the coulter system itself prevents damage at low excavation heights and large foreign bodies. At any time, however, a continuation of work is möglich.Eine further safety and wear reduction brings the integrated pivot point between Parallelogrammaufhängung and the crowd. This pivot allows for cornering without excessive wear and twisting. Even damage when reversing is avoided because the coulters can move laterally. Even an oblique insertion of the coulter bar leads to no load and bend the coulter more. It is possible as far as possible to use these coulters also in the front attachment since they can follow the steering movement, which was not yet possible.
