ROTARY MOWER Russian patent published in 2006 - IPC A01D34/73 A01D34/63 

FIELD: agricultural engineering, in particular, equipment used in mower cutter bar constructions.

SUBSTANCE: mower has bar with rotors, supporting shoes, and discharge board. Each rotor has cutting member made in the form of string with weight at its end. Other end of string passes through opening in round box-like casing and is pivotally connected with one end of coiled spiral spring. Other end of spiral spring is attached to round box-like casing rigidly fixed to rotor. Weights of odd rotors are rotating in single plane and weights of even rotors are arranged in other plane offset relative to said one plane downward by value equal to thickness of weight plus allowance by one tenth of the weight. Weights are located on rotors with 90 deg offset on rotational circumference relative to one another. End of coiled spiral spring, to which string with weight is attached, has size exceeding that of opening where string passes.

EFFECT: improved quality of shear and stabilized operating process.
