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. 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.
"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."
La comodidad y la facilidad de operación han sido los principales criterios de diseño en cada aspecto de la estación del operador. El interior amplio y espacioso, y el piso libre de obstáculos, proporcionan un entorno de trabajo cómodo, con excelente espacio para la cabeza, los hombros y las piernas, lo que permite mantener la productividad al máximo y la fatiga al mínimo. El asiento ajustable y los controles de bajo esfuerzo mantienen al operador cómodo durante toda la jornada de trabajo.
Unlike in a conventional front loader, the lift arms in these machines are alongside the driver with the pivot points behind the driver's shoulders. Because of the operator's proximity to moving booms, early skid loaders were not as safe as conventional front loaders, particularly during entry and exit of the operator. Modern skid loaders have fully enclosed cabs and other features to protect the operator. Like other front loaders, it can push material from one location to another, carry material in its bucket or load material into a truck or trailer.
