The invention discloses an eight-wheel four-transmission-driven large tractor. A power assembly, a driving cab and the like are fixedly mounted on a chassis (40) of the tractor, and four pairs of wheels which are connected and assembled by short bridges are mounted at the lower part of the chassis; after the output torque of a diesel engine (21) is converted into four forward gear speeds and four backward gear speeds, the wheels are driven by high and low speed conversion devices, assembly short bridges of the wheels, accessory differential mechanisms of the assembly short bridges, power input shafts and universal transmission shafts thereof in a secondary differential manner; through a power distribution shaft (7), a first-level transmission shaft of a gear box (42) transmits a rear power output shaft (48) by a first-level belt and transmits a front power output shaft (33) by a third-level belt; a steering wheel (14) controls the turn of the two pairs of front wheels through a hydraulic mechanism; a foot brake pedal synchronously brakes the eight wheels by a coupling mechanism and a pneumatic mechanism; large agricultural machines are respectively mounted on a front hydraulic suspension rack and a lower hydraulic suspension rack in a matching manner of the chassis, so that the tractor can perform dual-procedure agricultural operations. The tractor disclosed by the invention can be converted and mounted into a loading machine, and then can be driven backwards so as to perform loading operations.
