The present invention addresses the problem of providing a crawler tractor that facilitates cost reduction by using the same frame structure as a wheel tractor. Provided is a crawler tractor in which power is transferred from an engine (3) to drive wheels (22) of a crawler-type traveling apparatus (2) via a transmission case (5) and a front drive axle (6), said crawler tractor being provided with a pair of main frames (10), a pair of track frames (21), a pair of lower frames (27), a pair of rear beams (33), and a pair of rear housings (34). The front sections of the pair of main frames (10) are fixedly coupled to the front sections of the pair of track frames (21) via the front drive axle (6); the longitudinal intermediate sections of the pair of main frames (10) are fixedly coupled to the pair of lower arms (27); and the back sections of the pair of main frames (10) are fixedly coupled to the pair of rear housings (34) via the pair of rear beams (33). |
