El único motor (de gasolina o diésel) de esta máquina suele estar acoplado en la parte trasera, en el punto de unión entre los brazos de la cuchara y el chasis. Cuenta con un sistema hidráulico para la elevación de la cuchara o para permitir el montaje de otros accesorios. El chasis se desplaza sobre un sistema de orugas o de neumáticos, siendo más habitual este último con una distribución de cuatro neumáticos de igual diámetro repartidos equitativamente a los lados.[cita requerida]

Skid-steer loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and where the left-side drive wheels can be driven independently of the right-side drive wheels. The wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. Turning is accomplished by differential steering, in which the left and right wheel pairs are operated at different speeds, and the machine turns by skidding or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. As with tracked vehicles, the high ground friction produced by skid steers can rip up soft or fragile road surfaces. They can be converted to low ground friction by using specially designed wheels such as the Mecanum wheel. Skid-steer loaders are capable of zero-radius, "pirouette" turning, which makes them extremely maneuverable and valuable for applications that require a compact, agile loader. Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a multi-terrain loader.[1]
The original skid-steer loader arms were designed using a hinge at the rear of the machine to pivot the loader arm up into the air in an arc that swings up over the top of the operator. This design tends to limit the usable height to how long the loader arm is and the height of that pivot point. In the raised position the front of the loader arm moves towards the rear of the machine, requiring the operator to move extremely close to or press up against the side of a tall container or other transport vehicle to get the bucket close enough to dump accurately. At the highest arm positions the bucket may overflow the rear of the bucket and spill directly onto the top of the machine's cab.

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.
