One way to see if efficiency is the same (which is not) is to use a formula.
Fluid power Horsepower and mechanical horsepower from an engine is different because of efficiency losses. For instance If I have a 25Hp tractor the actual output at the drive wheels (if it is hydraulic drive) is about 2/3 of the 25HP of the engine. If that 25Hp tractor was gear drive you get about 90% efficency or so. (I dont feel like looking it up in my Hydraulic system manuals, I would spend 15 minutes looking for the books in a closet)
