Description
The Vintage Steam Roller – Traction Engine
A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning ‘drawn’, since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway locomotives – that is, steam engines that run on rails.
Traction engines tend to be large, robust and powerful, but heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative prime mover was the draught horse.
They became popular in industrialized countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed.
Traction engines were cumbersome and ill-suited to crossing soft or heavy ground, so their agricultural use was usually either “on the belt” – powering farm machinery by means of a continuous leather belt driven by the flywheel – or in
pairs, dragging an implement on a cable from one side of a field to another.
