SOIL CULTIVATION IMPLEMENT FOR ATTACHMENT TO A TOWING VEHICLE Russian patent published in 2018 - IPC A01B63/02 A01B49/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to tillage tools. Ground-treatment device comprises a base frame and arranged thereon soil working tools and at least one additional ground-treatment device, including a further frame and arranged thereon soil working tools. Additional ground-treatment device via at least one hinge point in the height movable with respect to the base frame is arranged, whereby the mobility can be limited by limiting means. Chassis, comprising at least one impeller and at least one frame also via at least one hinge point in the height movable with respect to the base frame is arranged. In a lowered position, the ground cultivating tools and the additional ground-treatment device are operatively connected and in a raised position are lifted above the floor. Chassis with at least one connecting element is connected with the additional ground-treatment device. In a raised position of the ground working apparatus to the towing vehicle at least one connecting element is formed or disposed with possibility to transfer the part of the weight the additional ground-treatment device to the chassis and the other part of the weight to the base frame, and in a lowered position of the ground working apparatus to the towing vehicle – with possibility to transfer the part of the weight of the chassis on the additional ground-treatment device in the direction of the soil.

EFFECT: simplification of the tractor axle load distribution unit design is ensured.
