The invention discloses a four-wheel drive tractor gearbox assembly which comprises a front speed change assembly, a main speed change assembly, a rear speed change assembly and a differential assembly, the input end of the front speed change assembly is connected with an output shaft of a diesel engine through a clutch, and the output end of the front speed change assembly is connected with the input end of the main speed change assembly. The output end of the main speed change assembly is connected with the input end of the rear speed change assembly, the output end of the rear speed change assembly is connected with the rotary cultivator output assembly, the differential mechanism assembly is arranged below the main speed change assembly, and the differential mechanism assembly is connected with a shaft II of the main speed change assembly through a basin angle gear and a rear basin angle gear shaft connected with the basin angle gear. The problems that front and rear wheels are asynchronous and tires slip when an existing four-wheel-drive tractor drives are solved.
