ROTARY RAKE-TEDDER Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: rotary rake-tedder has working tool hitched to tractor, beam mounted on working tool by pivot joint positioned on beam end faced to working tool in symmetry with beam longitudinal axis. Rotors with V-belt drive are mounted on wheels and provided with mechanism for lifting rotors to transport position. Beam pivot joint and drive pulley of V-belt drive are arranged in axially aligned position. Rotor lifting mechanism is of leverage-cable type. Cable guiding rollers are mounted on beam pivot joint shaft. EFFECT: reduced labor intensity for moving rake-tedder between transport and working positions, reduced material usage of drive and enhanced reliability in operation. 2 cl, 2 dwg
