APPARATUS FOR DETERMINING TRACTION RESISTANCE OF MOUNTED AGRICULTURAL MACHINES AND TOOLS Russian patent published in 2019 - IPC G01L5/13 A01B59/06 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to technical means for laboratory-field research of agricultural machines and implements mounted on mobile power equipment. Device for determining traction resistance of mounted agricultural machines and tools comprises tractor with hydraulic suspension system, attached implement and intermediate plate. Device is equipped with fixed on intermediate plate with possibility of rotation of horizontally located main and auxiliary shafts. On shafts there are vertically rigidly installed levers of identical length, to ends of which pivotally connected are tractions of hydraulic suspension system of tractor. On the above shafts auxiliary levers articulated with each other by articulated rod are rigidly secured. Rigidly attached to one of shafts is measuring lever, end of which rests against force sensor mounted on intermediate plate.

EFFECT: higher accuracy of determination of horizontal component of traction resistance due to elimination of influence of lateral and vertical components on the side of hydraulic suspension system of tractor.
