On the primary shaft of the tractor there is a driving gear that sets the intermediate shaft in motion. A block of gears is located on the intermediate shaft, the gears of which are rigidly connected to the shaft and are often manufactured as a single component part. On the secondary shaft, driven gears are located, which can be located on the splines of the shaft and move along them, or rotate on the hubs, in which case their longitudinal movement is excluded, and the transmission is turned on by connecting the gear to the shaft with a sliding clutch, often equipped with a mechanism that equalizes the angular speeds of the shaft and gears - a synchronizer. Cam clutches are often used for the same purpose in unsynchronized gearboxes of sports cars or special vehicles.
