The invention provides a front drive axle assembly of a harvester and belongs to the technical field of agricultural machinery. Technical problems of low transmission efficiency, poor reliability andthe like of stepless speed change are solved. The harvester front drive axle assembly comprises a main box body, a first shaft, a planetary reduction mechanism, a differential mechanism and a second shaft connected with the differential mechanism, wherein a belt wheel is arranged at one end of the first shaft, the planetary reduction mechanism comprises a planetary frame connected with the secondshaft and a center gear shaft capable of driving the planetary frame, the planetary frame is provided with a gear ring, and the first shaft is provided with a gear part meshed with the gear ring; themain box body is provided with an HST hydraulic stepless speed change driving device, an input shaft and an output shaft of the HST hydraulic stepless speed change driving device are connected with afirst shaft and a center gear shaft respectively, tail end transmission boxes are arranged on the two sides of the main box body respectively, the main box body is connected with the tail end transmission boxes through a front bridge, and the differential mechanism is in transmission connection with the tail end transmission boxes. The planetary speed reducing mechanism is combined with the HST hydraulic stepless speed change driving device, transmission efficiency is high, and reliability is good.
