SUBSTANCE: agricultural harvester which has at least one axle fitted with tyres and at least one additional axle fitted with tyres and can be operated as a slave or leading axle with the ability to disconnect or connect the all-wheel drive and the pressure control system in the tyres which comprises changing means for the tyre pressure and the control unit. At least one additional axle is fitted, for example, with the tyres, the pressure in which is increased at connecting the all-wheel drive as compared with the state of the off-wheel drive due to the fact that the control unit detects connection or disconnection of the all-wheel drive and initiates the pressure change in the tyres by using the pressure control therein.
