Which Skid Steer to Rent?
Bigger isn't always better: Smaller machines work great in tight areas (to backfill inside basements, for example), and in wooded areas where the trees are fairly close together. Smaller machines also do less damage to finished lawns. Bigger machines often have bigger buckets and can obviously lift heavier stuff.
Skid steers with tracks are often called compact track loaders. Tracked machines are gentler on lawns and less likely to get stuck, but they will cost about 25 percent more to rent.
You use levers to steer a skid steer, and either hand joysticks or foot pedals to control the bucket and lift arm. You'll find pros that prefer one over the other, but the learning curve on both is similar. Go with the hand controls if you're still bothered by that old high school knee injury, or do the opposite if you have trouble with your wrist.
Skid steers are available at some rental centers, and most heavy-equipment dealers rent them as well.
