The first three-wheeled, front-end loader was invented by brothers Cyril and Louis Keller in Rothsay, Minnesota, in 1957.[2] The Kellers built the loader to help a farmer, Eddie Velo, 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.[2]

The 272D XHP and 299D XHP high-flow models make 106 hp and 277 lbs.-ft. peak torque. Rated operating capacity is 3,600 lbs. for the 272D XHP and 3,185 lbs. for the 299D XHP at 35 percent of tipping load. Operating weight for the 272D XHP is 9,304 lbs. and 11,647 lbs. for the 299D XHP. Hydraulic systems deliver 40 gpm of flow at 4,061 psi, producing 94 hydraulic horsepower.


"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."
SSL (skid steer loader) refers to the standard wheeled machine.  CTL (compact track loader) and MTL (multi-terrain loader) refer to different undercarriage designs.  CTLs feature a steel embedded track and steel undercarriage components for maximum life in many applications.  MTLs have a rubber track undercarriage that delivers lower ground pressure compared to an SSL and CTL so they don’t tear up the ground as badly.
Skid steers are dual-powered through their diesel engines and hydraulic pumps and systems. Hydraulic systems use pressurized, or hydraulic, fluids to power their associated machinery, rather than other fuel sources or the raw flow of materials. They're a vital component to your machine's overall output and getting the best skid for your project operations and budget.

Our four highly versatile skid steers, ranging from 68.4 to 70.7 hp, are up to whatever daunting challenge you throw at them. Each is built around one of YANMAR’s powerful, fuel-efficient Final Tier 4 diesel engines, so they won’t back down from even the toughest job. With rated operating capacities from 1,650 to 2,700 pounds, and two easy-to-operate QuickAttach™ mounting systems, these machines are also rugged enough to handle just about any attachment you need. Couple that with spacious, high-visibility operator’s areas – built for comfort and safety – and you can work a long day without feeling like you did.
Outfitting new and old equipment with Tier 4's suite of equipment technology is another way to improve the lifespan and efficiency of a skid steer purchase. Tier 4 Technology brings innovative, personalized upgrades to the engine electronics, fuel and air systems of a unit, explicitly based on that unit's engine size, routine tasks and jobsite location.

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.
