Starkweather-Moore Expedition: Beyond the Mountains of Madness
This is a tracked vehicle with a boxy cab. The heated cab seats five passengers, in pairs (on bench seats), beside the driver. Two doors on each side allow access. The engine and fuel tank are mounted in the back. The engine is a 200 cubic inch Ford four cylinder gasoline engine, producing 40 HP at 2200 RPM. Features include an inertia (hand cranked) starter, and a one gallon oil tank. The engine uses one gallon of gasoline per hour; total fuel capacity is 18 gallons.
Overhauls and track lubrication are needed after 100 hours of operation. The tractor can tow 3000 pounds of sleds over the snow.
The driver directs the tractor with two steering brakes, controlling a “Cletrac” geared differential; basic operation is possible for anyone, but careful steering and operation on soft surfaces requires some experience.
