Had a day off Friday with some folks into Springfield Mo, stopped at a Tired Iron rally.

The traction engine, in the form recognizable today, developed partly from an experiment in 1859 when 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.

As a child a grew up around Traction Engines and Rallies as my late father had 7 Engines though by the time I was an adult he had sold them all off,Though i still know how to drive one. When he passed away he still had a 1/3 scale full working minature.

Alrighty! If my dad had those he'd put me to work on the nasty places and not allow me to move em, alas wisely so.
