Steam Tractors were scaled down versions of Road Locomotives which came about after changes in the law allowed one man to drive an engine providing it was below 5 tons in weight.
Nearly all steam tractors were built with compound cylinders and 3 road speeds, they were designed to be fast on the road and found favour among businesses who needed to move lightweight items around relatively quickly.
All the major steam manufacturers in the post Victorian era produced steam tractors and competition between builders as to who had the best model was fierce with several trials being setup to prove an overall winner. Winning these trials present a big marketing opportunity in this competitive market.
This area will be expanded soon.
