How hydrostatic drives make bulldozers safer

Dynamic braking means that the operator of a hydrostatic dozer has only one brake pedal to worry about. In contrast, a powershift dozer has both a deceleration pedal and a brake pedal. When you release the throttle on a hydrostatic-driven dozer, the hydraulic pressure in the system stops the machine. This means that the dozer will not roll backward when the operator stops it on a slope.

Smooth operator: The hydrostatic drive allows the operator of the pipe-laying dozer to place the pipe into the trench with ease, which is critical when there are workers in the trench to help place the pipe. Continuously variable speed allows the operator to move the machine slowly without the rush of upshifting or downshifting.

Easier to operate: Hydrostatic dozers help inexperienced operators work faster and make experienced operators more productive. There's nothing to notice in the cab, as these sophisticated machines take care of power management and, in some cases, blade control. This allows him or her to pay more attention to nearby machines and people, helping to improve job site safety.
