AUTOMATICALLY CONTROLLED GEARS FOR TOOL WITH ROTARY DRAWBAR Russian patent published in 2015 - IPC A01D34/00 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agricultural equipment. The harvesting tool comprises a frame, a drawbar, a tool operatively attached to the frame, the first, second and third gears, the drive line assembly with variable length operatively attached to an output shaft of the second gear at its one end and operatively attached to the input shaft of the third gear at its other end, and a control connecting element with a variable length, operatively attached at one end to the housing of the second gear, and at the other end - to the third gear housing. Agricultural harvesting tool with a rotational drive line and the frame, which is made with the ability to operate in a plurality of positions, comprises a frame, a drawbar, a tool connected to the frame by connection which enables the tool movement relative to the frame, the rotary gear unit with an upper gear and a lower gear, a rear gear, an unit of the first drive line and an unit of the second drive line. The mower with automatically controlled gear comprises a frame with wheels, a header, cutting elements for cutting plants, a drawbar, a front gear, a rear gear, a telescopic drive line, an actuator, and a gear control device. The mower with automatically controlled gears comprises a frame with wheels, a header, cutting elements, a drawbar, the first, second and third gears, the first universal joint, a telescopic drive line, a second universal joint, an actuator, and a gear control device. The method of controlling the rear gear on the mower comprises attachment of the gear control device at its front end to the front gear and the functional attachment with the ability of rotation of the gear control device on its rear part to the rear gear around a substantially horizontal axis, whereby when the drawbar is rotated relative to the frame the rear gear and the telescopic drive line are respectively rotated to maintain the working alignment of the front and rear gears.

EFFECT: increased driving power from the tractor to the working components of the machine is provided.
