Agricultural implement frame - has booms spring-mounted on transverse rail to allow vertical deflection under overload

摘要

The agricultural implement frame is for mounting on a tractor, having a horizontal transverse rail from which independent booms extend in the travel direction, accommodating seedbed preparation or other implements. The booms are detachably screwed to the rail. The screws (12-15) are equipped with elastic components (16), allowing the booms (2) to deflect vertically for a limited amount under overload, and to return automatically afterwards to the working position. The screws (13) can be equipped with plate springs (16), or there can be plates of resilient material between the boom and the rail (1).
