El sistema contra calado aumenta al máximo la potencia de la máquina permanentemente, haciendo coincidir el par motor con los requisitos de operación del sistema hidrostático y del sistema del implemento. Esta característica de detección de carga evita que el motor se cale, aun durante la operación a acelerador parcial, lo que mantiene la productividad alta y el consumo de combustible bajo.
El sistema hidráulico de la máquina se ha fabricado para que proporcione potencia y fiabilidad máximas. Además de suministrar potencia a las ruedas, este sistema también proporciona las funciones de levantamiento e inclinación del cargador, alimenta el circuito auxiliar para impulsar las herramientas e impulsa el ventilador de enfriamiento del motor. Las bombas hidráulicas se impulsan directamente con el motor para obtener el máximo rendimiento hidráulico y una excelente fiabilidad sin utilizar correas. El sistema hidráulico también cuenta con:
Zupancic says it's all about the size of the site and the use the skid steer is put to. "These construction and jobsite applications require a little more power and bucket size, but are still in a confined enough space that contractors cannot bring in the big machines," he explains. "Sometimes the operator doesn't need the extra muscle of a larger skid-steer loader and finds it more economical to have a 50- to 70-hp machine."

Indicadores del sistema de alarma para el operador: restricción del filtro de aire, salida del alternador, posabrazos levantado/operador fuera del asiento, temperatura del refrigerante del motor, presión del aceite de motor, activación de las bujías, restricción del filtro hidráulico, temperatura del aceite hidráulico, freno de estacionamiento conectado

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.
Some models of skid steer now also have an automatic attachment changer mechanism. This allows a driver to change between a variety of terrain handling, shaping, and leveling tools without having to leave the machine, by using a hydraulic control mechanism to latch onto the attachments. Hydraulic supply lines to powered attachments may be routed so that the couplings are located near the cab, and the driver does not need to leave the machine to connect or disconnect those supply lines.

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]
