Steam traction engine

Victorian illustration to download showing a picture of a steam traction engine with a two-man crew, one man to steer the engine and one to adjust the wheels. This is Bray’s Patent traction engine (1850s). The rear wheels had a system of adjustable teeth which sank into the ground and obtained a firm hold, a big advantage in difficult terrain. A series of experiments with this traction engine in 1858 showed that it was highly effective for use in agriculture, transport and the army, with savings made in time and fuel.
