FIELD: process engineering.
SUBSTANCE: invention relates to agricultural machinery. Proposed mechanism serves to distribute natural load from wheeled tractor front axle to extra propulsor. Cylindrical thrust mechanism is mounted at tractor frame by means of welded corner plates. Said mechanism consists of hydraulic cylinder, hydraulic control valve, hydraulic pump, pump cut in lever, elastic fluid feed hoses. Hydraulic cylinder rod thrusts against the end of dual semi-elliptical sheet spring. Spring central part is articulated with bracket hinge at tractor frame center. Said spring rests on thrust piece mounted on extra drive axle and provided with limiter.
EFFECT: better floatation.
