The difference between a wheeled skid steer loader and one that sits on tracks involves more than just one having wheels and one moving on tracks. Wheels or tracks affect how they operate on different kinds of terrain. Track loaders work better on uneven soft terrain that a wheeled loader may sink into, and a wheeled loader operates best on asphalt, concrete, and pavement. Although a wheeled skid steer offers the advantage of tighter maneuverability and greater speed, track skid steer loaders can carry heavier loads.
