Zusammenfassung:	An auto-leveling drive axle device for a wheel tractor, and leveling method. The device comprises a transmission device and a leveling device. The transmission device comprises a drive axle housing (2), a half-shaft bevel gear (3), a vertical transmission shaft (4), and a wheel-side planetary reduction gear mechanism (9). The vertical transmission shaft (4) has an upper end connected to an upper vertical shaft bevel gear (5) via a spline, and a lower end fixed to a lower vertical shaft bevel gear (11). The half-shaft bevel gear (3) is mounted on the drive axle housing (2) by means of a bearing, and meshes with the upper vertical shaft bevel gear (5). The lower vertical shaft bevel gear (11) meshes with a bevel gear of the wheel-side planetary reduction gear mechanism (9) to drive a wheel (8). The leveling device employs a hydraulic system, and the hydraulic system comprises a hydraulic solenoid-operated directional control valve (10) and a hydraulic cavity in communication therewith and provided below the dri
