Bobcat Company invented the world’s first skid-steer loader. Bobcat has celebrated a 50-year history of quality, performance and reliability. It’s no wonder they’re the world’s best selling skid-steer loader. When paired with a genuine Bobcat® attachment, each skid-steer model is a force to be reckoned with on your jobsite. And with more than a dozen models to choose from, you’ll find the right machine for any size job.
The Melroe brothers, of Melroe Manufacturing Company in Gwinner, North Dakota, purchased the rights to the Keller loader in 1958 and hired the Kellers to continue refining their invention. As a result of this partnership, the M-200 Melroe self-propelled loader was introduced at the end of 1958. It featured two independent front-drive wheels and a rear caster wheel, a 12.9 hp (9.6 kW) engine and a 750-pound (340 kg) lift capacity. Two years later they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, true skid-steer loader.[2] The M-440 was powered by a 15.5 hp (11.6 kW) engine and had an 1,100-pound (500 kg) rated operating capacity. Skid-steer development continued into the mid-1960s with the M600 loader.
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]
La amplia abertura de la cabina ofrece una vista excepcional de la herramienta. El ángulo inclinado del compartimiento del motor permite una excelente visibilidad de la parte trasera de la máquina. El espejo retrovisor estándar proporciona al operador una vista panorámica de la parte trasera y de la parte lateral de la máquina. Las ventanas laterales se quitan fácilmente para permitir la limpieza.

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.
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."
No over-digging. No undercutting. No wasted time, fuel or dollars. SiteControl helps eliminate rework by making reliable, repeatable precision a reality. CASE offers tailor-made hardware and software solutions for all positioning and measuring tasks in construction, including ways for businesses to improve productivity and lower costs – both on and off your machine.
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.
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]
