A crawler belt vehicle comprises a chassis having a first end portion and a second end portion, first wheels mounted on the first end portion of the chassis for rotation, a swing arm having a front end and a rear end mounted on the second end portion of the chassis for undergoing pivotal movement relative to the chassis about a first axis, driving shafts mounted for rotation about a second axis and connected to the front end of the swing arm for undergoing pivotal movement therewith, and second wheels are mounted on the driving shafts for rotation therewith. Beam members are connected to the front end of the swing arm for undergoing pivotal movement therewith. Wheel axles are mounted on the beam members for rotation about a third axis and for undergoing pivotal movement with the beam members. Third wheels are mounted on the wheel axles for rotation therewith and are disposed between the first wheels and the second wheels. Crawler belts are trained around the second wheels and the third wheels for rotation therewith. A driving mechanism is disposed between the second and third wheels for driving the second and third wheels.
