The invention relates to a transmission. The transmission comprises a box assembly, a gear shifting assembly, a main variable speed assembly, a differential speed shaft assembly and a front driving assembly. The gear shifting assembly, the main variable speed assembly, the differential speed shaft assembly and the front driving assembly are fixed to a box. The gear shifting assembly comprises a main variable speed gear shifting assembly body and a four-drive gear shifting assembly body. The main variable speed gear shifting assembly body and the four-drive gear shifting assembly body control gear adjusting of the main variable speed assembly and the differential speed shaft assembly correspondingly. The transmission is stable in performance, safe, reliable and compact in structure, rear wheel driving can be achieved when a transporting vehicle provided with the transmission travels on a light-load good road, differential speed four-drive is achieved when the transporting vehicle provided with the transmission travels on a light-load non-rigid road or on a full-load good road, differential speed locking four-drive is achieved when the transporting vehicle provided with the transmission travels on a full-load non-rigid road, the driving capacity of a tractor works in field transfer and road transport is improved advantageously, tyres are prevented from slipping or trapping, and the transmission meets the need of various road conditions and different driving modes.
