Structure of mechanism |
| Function |
Device embedded in the farm machinery which forms a tracted unit, required for connection to a towing vehicle, It is composed of a chassis and a coupling device to a tractor, It is usually used for machinery towed with at least two wheels, This system is used to control the direction of the structure via two arms which transmit the movement of the tractor to the machine, The pin which moves in the groove allows at a first time to transmit the rotational and translate movement as long as it don't circulate in the circular groove, In a second time when the pin circulate in the circular groove, the device only transmit the traction force, so the operator can better approach the turn, The connection anchor to the tractor allows a rotational movement to the rest of the mechanism which reduce the parasitic movements generate by the ground, |
