The invention provides a spiral-type crawler hiller. The machine comprises a chassis support part which is provided with an engine part, a speed-changing steering control part, a hilling mechanism and a hand-operation part, wherein the speed-changing steering control part is connected with a crawler walking part and the hilling mechanism; one end of an operation-adjusting part is arranged on the chassis support part; the left-side hilling cutters assembly and the right hilling cutter assembly of the hilling mechanism have a same structure and are arranged at the both ends of a support assembly and symmetrical about a hilling transmission; the hilling mechanism is placed between two ridges; and hilling cutters transport the soil at the bottom part between two ridges to the top of the ridges in a spirally conveying way, so the hilled soil is spirally transported and weeds on the ridges are cleared away at the same time. According to the spiral-type crawler hiller provided by the invention, the crawler walking part is driven by a crawler, so the passing abilities of vehicles are effectively improved; the speed-changing steering control part integrates the functions of deceleration and speed-regulation of a working device speed changer, so the weight of the whole machine is reduced and left turning and right turning are realized via a left-side rocker arm and a right-side rocker arm; meanwhile, gear shift in the process of marching is realized; operation is simple; and steering precision is high.
