Contrary to popular opinion, the horsepower rating of a skid-steer loader's engine, by itself, isn't an accurate way to compare one loader's performance to another, says Roesler. A loader with a high-horsepower engine could be wasting time, fuel and money, if that extra power is being used to spin the wheels rather than to dig or push dirt. A bigger engine also requires a bigger radiator, which requires a bigger frame. That, in turn, can limit the areas where the loader can work. An engine in which torque peaks at a relatively high engine rpm could die quickly under a load.
Maneuverability is another performance factor to consider.
For instance, the compact Bobcat 751 and 753 loaders, with their conventional wheelbases, can turn in a tighter circle than the longer-wheelbase Bobcat 763 and 773. The longer wheelbase, on the other hand, provides a smoother ride. Soil and surface conditions of your work site may also influence your choice of loaders. Loose sand and muddy soils can stop a skid-steer loader. The best way to size up how a skid-steer loader will actually help you save time and make money is to try it on for size.
