LMC 1500 LMC 1200. Logan Manufacturing Company was a US manufacturer of snowcats that ceased operation in 2000. LMC is both the tradename (brand name) and an acronym.. The company's earliest history started with a prototype tracked snow vehicle built in 1948 by engineers Roy France and Emmett Devine, of the Utah Scientific Foundation at Utah State University in Logan, Utah.
The Aerosport-Rockwell LB600 was a two-cylinder, two-stroke, air-cooled, horizontally opposed engine intended to power ultralights. It was developed in partnership by Aerosport and Rockwell International, based on a Rockwell-designed JLO snowmobile engine.
These sleds feature extremely powerful engines placed in chassis derived from racing models. The first-gen featured a Suzuki-produced, counterbalanced case-reed triple cylinder 2-stoke 900cc engine, which produced 161.5 horsepower. The engines came stock with triple tuned pipes, 38mm VM Roundslide Mikuni Carburetors and forged pistons.
The original snowmobile engine produced 40 hp (30 kW). Lowering the compression ratio not only de-rated the engine, but also made pull-starting easier and allowed it to run on lower-octane regular auto fuel. The resulting engine worked well, was de-rated to produce 30 hp (22 kW) at 5,500 rpm and proved reliable in service. [2]
As Polaris snowmobiles gained sales traction, Edgar Hetteen became an advocate of the new product line. [6] In order to promote the new snowmobile and prove its reliability and usefulness, in 1960 Edgar led a three-snowmobile, 1,200-mile trek across the Alaskan wilderness, starting from Bethel, Alaska. The trip took three weeks, and much of the ...
The Short track versions of the Bravo would do around 70 km/h and the long track would do around 55 km/h. Later Yamaha swapped the 249cc engine for a 246cc engine but little else changed and almost all parts were interchangeable. In the late 1990s Yamaha removed both short track models from the market and only the 136 inch track was available.
The company acquired a line of two-stroke engines that were originally designed and produced by JLO of Germany and marketed them under the Cuyuna brand name for snowmobile and later ultralight aircraft use. Later Cuyuna formed a subsidiary Two Stroke International, commonly known as 2si, to produce and market the
Though this was the United States's first introduction to the revolutionary rotary engine, OMC's hopes of success were dashed by heavy competition from other snowmobile brands, as well as by two winters of sparse snow. Snowmobile production came to an end in 1976, after a fiscal 1974 operating loss of $13.9 million.
