Hydrostatic Transmission System

Kawasaki's Hydrostatic Transmission (HST) system

Utilizing the closed loop axial piston pump K8V series and the high speed swash plate type axial piston motor M7V series in the closed circuit, highly efficient and powerful driving performance and smooth driving feeling can be achieved.


Combine Harvesters

HST system can be utilized on the applications that require high torque output at low driving speed or repeat reversing direction such as the wheel loaders, dozers, telehandlers, or combine harvesters and enables smooth driving speed adjustment without operating the gear shift.

Saving the fuel for the machine operation


The combination of highly efficient hydraulic components and electronic controller that provide the optimum performance can contribute to the fuel saving of the machine.
