TOWING DEVICE Russian patent published in 2014 - IPC A01B59/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular to mechanism of the towing device, and can be used during tillage operations. The device comprises the rigid, flexible and elastic bondings. The elastic power bonding comprises a multi-leaf type element, attached at two sides by the clamps to the horizontal rods-extensions, which in turn are rigidly fixed to the frame of the tractor, the support U-shaped levers covering the multiple-leaf spring and rigidly connected to the tractor frame, and the transverse adjusting plate for changing the horizontal position of the support levers. The device for connecting with the towed machine is located in the centre of the elastic element. The transverse adjusting plate is rigidly attached to the frame of inertial damper. The damper comprises a mechanical transmission made in the form of an inertial mechanism having a flywheel fixedly mounted on the shaft which, through the elastic sleeve is rigidly attached to the gear interacting with a rack bar supported by the clamping device. The rack bar is rigidly attached to the device for connecting with the towed machine.

EFFECT: invention provides reduction of dynamic magnification of the process of loading the machine and tractor unit during tillage operations.
