Skid loader
Operation

A Skid Steer loader can sometimes be used in place of a large excavator by digging a hole from the inside. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole. The skid loader reshapes the ramp making it steeper and longer as the excavation deepens. This method is particularly useful for digging under a structure where overhead clearance does not allow for the boom of a large excavator, such as digging a basement under an existing house.
The conventional bucket of many skid loaders can be replaced with a variety of specialized buckets or attachments, many powered by the loader’s hydraulic system. These include backhoe, hydraulic breaker, pallet forks, angle broom, sweeper, auger, mower, snow blower, stump grinder, tree spade, trencher, dumping hopper, ripper, tillers, grapple, tilt, roller, snow blade, wheel saw, cement mixer, and wood chipper machine.
History

The first three-wheeled, front-end loader was invented by brothers Cyril and Louis Keller (manufacturer) in Rothsay, Minnesota, in 1957. The Kellers built the loader to help a farmer mechanize the process of cleaning turkey manure from his barn. The light and compact machine, with its rear caster wheel, was able to turn around within its own length, while performing the same tasks as a conventional front-end loader.
The Melroe brothers, of Melroe Manufacturing Company in Gwinner, N.D., 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 engine and a 750-lb. lift capacity. Two years later they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, skid-steer loader. It quickly became the Melroe Bobcat. The term “Bobcat” is sometimes used as a generic term for skid-steer loaders. The M-440 was powered by a 15.5-hp engine and had an 1100-lb. rated operating capacity. Skid-steer development continued into the mid-1960s with the M600 loader.
Many manufacturers have their own versions of the skidloader (often referred to as a Skidsteer in the Construction Industry), including: John Deere, Case, JLG, JCB, New Holland, Gehl Company, Mustang, ASV, Caterpillar, Bobcat and more.
