The weight of the machine and horsepower has a bit to do with loader performance as well. When digging, or even just scooping from a loose pile of dirt, the machine's (ballasted) weight determines your maximum traction for pushing into the pile. The weight on these smaller machines also tends to set the upper limit on lifting capacity (before they tip), and finally, the front axel and tire ratings are something to consider. The slightly larger machine might have higher ratings on these.
