Which statement describes energy transfer in a skid steer with hydrostatic drive?

• A. Engine to hydraulic motors to drive wheels
• B. Engine to mechanical gears to wheels
• C. Engine to electric motors to wheels
• D. Engine to belts to wheels

Answer: (A)

In a skid steer with hydrostatic drive, energy moves through a hydraulic system: the engine powers a hydraulic pump, which pressurizes hydraulic fluid that is sent to hydraulic motors attached to the wheels. The motors then convert that fluid energy into rotational motion to drive the wheels. This is why the path is engine to hydraulic pump to hydraulic motors to drive wheels. It differs from mechanical gear drives, belt drives, or electric motor drives, which use gears/belts or electric motors instead of hydraulic motors to turn the wheels.
