The invention discloses a hydraulic screw crawler hiller. A motor part, a speed-change and steering control part, a hilling working mechanism, and a hand-held operation part are arranged on a chassis bracket part of the hiller. The speed-change and steering control part is connected with a crawler travelling part and the hilling working mechanism. In the hilling working mechanism, a left side hilling blade assembly and a right side hilling blade assembly have a same structure, and are symmetrically arranged on two ends of a bracket assembly, relative to a power transmission case which is arranged on the bracket assembly. A left side breadth adjustment mechanism and a right side breadth adjustment mechanism are arranged on the bracket assembly. A left hydraulic driving part and a right hydraulic driving part are connected with the power transmission case. The hilling working mechanism is positioned between two ridges. While screw conveying hilling is carried out, a weeding function is performed. The hilling working mechanism is controlled by a hydraulic pump-motor direct connection system, such that versatility is high. Crawler driving is adopted in the crawler travelling part, such that vehicle trafficability is effectively improved. A working device transmission function is integrated in the speed-change and steering control part, such that the total weight of the hiller can be reduced.
