This machine size's ROC allows it to lift the heaviest loads, such as moving pallets of brick or dumping loads of dirt into the back of trucks. "These machines also have the horsepower and hydraulic flow to tackle tough jobs and attachments," says Rostberg. "Attachments that perform best with a high-flow machine, such as a wheel saw or planer for road construction or a forestry cutter for site preparation, work best with these machines."
A skid-steer loader can sometimes be used in place of a large excavator by digging a hole from the inside. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole. The skid loader reshapes the ramp making it steeper and longer as the excavation deepens. This method is particularly useful for digging under a structure where overhead clearance does not allow for the boom of a large excavator, such as digging a basement under an existing house. Several companies make backhoe attachments for skid-steers. These are more effective for digging in a small area than the method above and can work in the same environments. Other applications may consist of transporting raw material around a job site, or assisting in the rough grading process.
"Knowing the specific applications the customer would like to perform will help a rental business determine the size and power of machine needed to most efficiently complete the tasks," says Rostberg. "Asking questions and getting to the core of the customer's work will help determine this. Also, while inquiring about the customer's needs, a rental business might discover opportunities to rent attachments that will help the customer more quickly and efficiently complete their job."

An extended reach design uses multiple hinges and parallel lifting bars on the loader arm, with the main pivot points towards the center or front of the machine. This allows the loader arm to have much greater operating height while retaining a compact design, and allows the vertical movement to be less of an arc and more straight-up vertical, to keep the bucket forward of the operator's cab, allowing safe dumping into tall containers or vehicles.
The wheels on a skid steer typically have no steering mechanism, they are in a fixed, straight line relative to the body of the machine. By turning the left and right wheel pairs at different speeds, the machine turns by skidding, or dragging its wheels across the ground. The rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. This skidding motion tears up the ground on which the machine operates.
