What Is HST?
Hydrostatic transmissions are relatively new and have been integrated into almost every new piece of farm equipment. Automatic and manual transmissions still dominate the passenger vehicle manufacturers, but in the heavy duty equipment field, hydrostatic transmissions have taken storm. HST drive trains are here to stay and for very good reasons.
How Does It Work?
An HST does not rely on gears that determine speed or direction and therefore does not need a clutch. The transmission is different in that it relies on fluid from a piston pump to be transferred through a series of tubes to the motor. The energy produced is what powers the vehicle for different speed rates and direction. Pushing the lever forward will result in a forward motion concurrent with the degree that the lever is pushed forward. The same goes for the reverse function. On Kubota tractors, the lever has been replaced with a fully functional pedal to make this operation even easier.
