The invention discloses a light-duty caterpillar tractor which comprises a machine frame assembly, a diesel engine, a clutch assembly, a speed changing box assembly, a drive system, tensioning devices, a walking mechanism, a driving seat assembly and a hydraulic system. An output shaft of the diesel engine serves as an input shaft of the clutch assembly, and an output shaft of the clutch assembly serves as an input shaft of the speed changing box assembly. The power of the diesel engine is transferred to the walking mechanism through the clutch assembly, the speed changing box assembly and the drive system. The walking mechanism comprises caterpillar bands, driving wheels, guide wheels, supporting wheels and thrust wheels, wherein the driving wheels, the guide wheels, the supporting wheels and the thrust wheels are arranged on the inner sides of the caterpillar bands, the guide wheels are installed on the tensioning devices and are controlled to move by the tensioning devices, and the caterpillar bands are kept in a tensioned state through movement of the guide wheels. The light-duty caterpillar tractor has the advantages of being compact in guide wheel structure, light in weight, good in bearing capacity and the like. In addition, the guide wheel of the light-duty caterpillar tractor has the advantages of being simple in structure, light in weight and the like.
