Agricultural implements

摘要

An agricultural implement having a transversely extending horizontal frame beam which is composed of pivoted sections. The pivots are located at a substantial spacing under the frame beam sections and connected to the frame beam sections by arms which extend obliquely downwards from the ends of the frame beam sections. The sections may be lifted by hydraulic rams. If the implement is mounted at the front of a tractor via a three point linkage, the lower links of said linkage are slidingly extensible.
