In Great Britain, a number of traction engine builders attempted to produce a design of agricultural engine that could pull a plow directly, in place of a team of horses. . However, the heavier and wetter soils found in Britain meant that these designs were not successful, being less economical to use than the teams of horses they were intended to repla
Typical exhibits include: traction engines, steam rollers, steam wagons, and steam cars. Often, the scope is widened to include other historic exhibits such as stationary engines, internal-combustion -powered road transport, agricultural and construction vehicles, working horses, woodcraft and the like. A typical steam fair consists of:
Steam-powered showman's engine from England. The history of steam road vehicles comprises the development of vehicles powered by a steam engine for use on land and independent of rails, whether for conventional road use, such as the steam car and steam waggon, or for agricultural or heavy haulage work, such as the traction engine.
In 1859, Aveling invented the traction engine when he modified a Clayton & Shuttleworth portable engine, which had to be hauled from job to job by horses, into a self-propelled one. The alteration was made by fitting a long driving chain between the crankshaft and the rear axle.
The massive 40-120 (and later 140) HP engines were brought out in 1908 and their two stories height allowed the driver (engineer) to see over the cross-compound engine. They built engines in nominal horsepower sizes: 13 hp, 16 hp, 20 hp, 25 hp, 32 hp and 40 hp. The "140" referenced above was the "brake horsepower."
Even teams of 16 horses were not strong enough to pull gang plows through the dense bunch grasses whose roots grew as deep as 6 feet (1.8 m) into the earth. The first small steam traction engines, adapted from the design of stationary engines used to thresh wheat and gin cotton, weren't strong enough and broke down repeatedly. [7]
The first proper traction engine, in the form recognisable today, was developed in 1859 when British engineer Thomas Aveling modified a Clayton & Shuttleworth portable engine, which had to be hauled from job to job by horses, into a self-propelled one. The alteration was made by fitting a long driving chain between the crankshaft and the rear axle.
