DUMP RAKE Russian patent published in 2009 - IPC A01D76/00 

FIELD: agriculture.

SUBSTANCE: this invention relates to agricultural engineering and can be used in cured or wizened plant windrower. The dump rake comprises frame, rake bar, lifting shaft as well as liftering and lowering mechanism. The rake bar is fitted with spring teeth. The liftering rake is equipped with cantilever fitted cleaning rods located between spring teeth. Each cleaning rod consists of two rods of unequal length coupled together with a gland. The gland is located in front of the spring teeth. The shorter rod is intended for stroke limitation in a vertical plane.

EFFECT: when windrowing, the shorter hinged rod moves down by gravity and enables the spring teeth to return to their operating position, which improves rake performance reliability.
