"Find out as much as you can about the job the skid steer is being put to," says Zupancic. "Get an idea of the dimensions of the site - especially the minimum dimensions. The worst thing for a contractor is to feel his rental provider hasn't given his business enough thought and has recommended a machine that won't fit within the most vital dimensions of the jobsite."
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.
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.
