In the meantime, a gasoline-powered [[motor home]] was built by Lombard for Holman Harry (Flannery) Linn of [[Old Town, Maine]] to pull the equipment wagon of his dog & pony show, resembling a [[tram|trolley]] car only with wheels in front and Lombard crawlers in rear. Linn had experimented with gasoline and steam-powered vehicles and six-wheel drive before this, and at some point entered Lombard's employment as a demonstrator, mechanic and sales agent. This resulted in a question of proprietorship of patent rights after a single rear-tracked gasoline-powered road engine of tricycle arrangement was built to replace the larger motor home in 1909 on account of problems with the old picturesque wooden bridges. This dispute resulted in Linn departing Maine and relocating to Morris, New York, to build an improved, contour following flexible lag tread or crawler with [[independent suspension]] of [[halftrack]] type, gasoline and later [[Diesel engine|diesel]] powered. Although several were delivered for military use between 1917 and 1946, Linn never received any large military orders. Most of the production between 1917 and 1952, approximately 2500 units, was sold directly to highway departments and contractors. Steel tracks and payload capacity allowed these machines to work in terrain that would typically cause the poorer quality rubber tyres that existed before the mid-1930s to spin uselessly, or shred completely.{{Citation needed|date=January 2010}}

Linn was a pioneer in snow removal before the practice was embraced in rural areas, with a nine-foot steel v-plow and sixteen foot adjustable leveling wings on either side. Once the highway system became paved, [[snow plow|snowplowing]] could be done by [[four wheel drive]] trucks equipped by improving tyre designs, and the Linn became an off highway vehicle, for [[logging]], [[mining]], dam construction, [[arctic exploration]], etc.{{Citation needed|date=January 2010}}
