FIELD: transport.
SUBSTANCE: invention relates to agricultural machinery, namely to auxiliary devices designed to increase non-four-and-four wheeled tractor cross-country capacity. Auxiliary device to increase non-four-and-four wheeled tractor cross-country capacity represents auxiliary positively locked drive axle mounted with the help of welded thrusts and spring-loaded vertical power hydraulic cylinders arranged between front and rear axles of the tractor, perpendicular to vector of tractor motion, and engaged via p.t.o-box with gearbox. It allows redistribute tractor front weight to additional drive axle via pressure cylinder mechanism depending upon operating conditions. To add to system of horizontal stiffness, auxiliary drive shaft is secured to tractor frame by two reactive tie-rods.
EFFECT: higher cross-country capacity, reliability, simplified design.
