A machine configuration system which can realize different works by work machines, industrial machines, agricultural machines, military vehicles, remotely-controlled autonomous, etc. machines, by means of components and equipments having capability of fixation to various locations of the main chassis and main chassis with palette or single type, four-wheel drive and platform with rotation through four wheels.

A method for controlling a transmission device of a vehicle. The device includes a hydraulic transmission. The displacement of the hydraulic pump is controlled so that it delivers to the n hydraulic motors a constant flow that is proportional to the speed of the wheels rotated by the drive. The displacement control of the hydraulic pump is carried out by a correction constant and a correction variable. The correction variable is determined in real time. The correction constant includes the sum of a theoretical constant and an adjusted constant. The theoretical constant is defined according to the theoretical behaviour of the hydraulic transmission. The adjusted constant is defined and corrected when the vehicle is in predetermined conditions of use, in order to reflect the real state of the vehicle.

A work vehicle includes a rear frame, a front frame rotatably attached to the rear frame, a work implement attached to the front frame, a motor disposed on the front frame, a differential device connected to the motor, and a drive shaft connected to the differential device.
