The first three-wheeled, front-end loader was invented by brothers Cyril and Louis Keller in Rothsay, Minnesota, in 1957. The Kellers built the loader to help a farmer, Eddie Velo, mechanize the process of cleaning turkey manure from his barn. The light and compact machine, with its rear caster wheel, was able to turn around within its own length, while performing the same tasks as a conventional front-end loader.
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.
Comfort is a prerequisite to look for when purchasing a tractor, since the vehicle is used by farmers to do strenuous work such as hauling. Comfortable tractors are furnished with various features and capabilities that make them easy to use and manage while effectively performing their farm operations. Tractors are custom made and ensure comfort so that operators can work for longer periods without straining. The larger the operator's property, the more a comfortable tractor is required. A comfortable tractor is also multifunctional as it can haul, dig, lift, and pull heavy things.

The two main sections of an excavator are the undercarriage and the house. The undercarriage includes the blade (if fitted), tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks. The house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the undercarriage by way of a center pin. High pressure oil is supplied to the tracks' hydraulic motors through a hydraulic swivel at the axis of the pin, allowing the machine to slew 360° unhindered.
