ABSTRACT:
A compact crawler type tractor having an excellent turning feeling is provided. A hydraulic speed change mechanism for turning includes a hydrostatic transmission pump for turning and a hydrostatic transmission motor for turning, and is characterized in that the hydrostatic transmission pump for turning is a variable displacement pump, and an output of the hydrostatic transmission motor for turning is input into a differential mechanism. By combining the hydrostatic transmission pump for turning and the hydrostatic transmission motor for turning and the differential mechanism, an excellent turning feeling can be obtained.
