In [[Great Britain]], the term ''steam tractor'' is more usually applied to the smallest models of traction engine &ndash; typically those weighing below 5 tons for the engine to be single manned (up until 1923 anything above had to be manned by at least two people; a driver and steersman); used for hauling small loads on public roads.<ref name=Ranieri29>{{cite book |last=Ranieri |first=Malcolm |date=2005 |title=Traction Engine Album  |publisher=Crowood Press |page=29 |isbn=1861267940}}</ref> In 1923 the weight limit was raised to 7.5 tons.<ref name=Burton75>{{cite book |last=Burton |first=Anthony |date=2000 |title=Traction Engines Two Centuries of Steam Power| publisher=Silverdale Books |page=75 |isbn=1856055337}}</ref>  Although known as ''light steam tractors'', these engines are generally just smaller versions of the road locomotive.

They were popular in the timber trade in the UK, although variations were also designed for general light road haulage and showman's use.<!--<ref name=Ranieri106 /> will cover showman's use-->

The most popular of these designs was probably the [[Richard Garrett & Sons|Garrett]] 4CD, meaning ''4'' nominal horse power [[Compound locomotive|compound]].<ref>''Garrett Steam Tractors & Rollers'', R. A. Whitehead, 1999</ref>
