The Lombard steam log hauler was the original crawler type overland tractor. It had crawler treads and skids in front for steering. It required 4 men (an engineer, fireman, pilot or steersman, and conductor) to operate it. In 1901, Alvin Lombard (1856-1937) was granted a patent on the track, which would give wheels traction in the snow, and in that year he built the first power log hauler at the Waterville Iron Works in Waterville, Maine. This type of track was the ancestor of all crawler type tracks such as military tanks, bulldozers, tractors, etc. The first log haulers were steered by horses. This steam crawler-tractor emancipated horses from the killing work of hauling trains of sleds over iced roads in the winter woods of the United States and Canada. Later, a steersman sat on the front of the sled, guiding the hauler by a large iron wheel that turned the runners. They had no brakes.
Eighty-three Lombard steam log haulers were known to have been built up to 1917 when production switched entirely to internal combustion engine powered machines, ending with a Fairbanks diesel powered unit in 1934. The steam log haulers were mostly used in Maine and New Hampshire but three went to Russia, and one each to Wisconsin and Michigan.
The steam log haulers had an advantage over horses and oxen in that they could tow many more two-sleds than any team.
