3 inch scale "Caradoc" steam tractor - stock code 7027

I've always been an admirer of John Haining's designs, he specialized in the unusual and quirky prototypes - Fowler ploughing engines, Durham & North Yorkshire (all of which were lost in full size, his models being what most people know the design by), the completely bonkers Suffolk Dredgin tractor. Every now and again he applied his formidable design abilities to something completely off the wall - "Caradoc" was one of those things, his imagining of steam having survived into the modern era and being used in a contemporary agricultural tractor.

Silver soldered vertical copper boiler, 90psi working pressure, feed by mechanical pump with auxiliary hand pump. Twin cylinder double high engine, cast iron cylinders with slide valves actuated by Stephenson's gear, two speed transmission by gear and chain to back axle.

The engine runs like a sewing machine and makes steam like it's going out of fashion. Must be said Connor and were I impressed by this one (Ashley too, although he wouldn't admit it). In low gear it feels like it could pull a house down, high gear is a usable ratio for the rally field - still got some torque, but at the same time you'll beat any of the 3 inch Burrell to the beer tent hands down. There's some footage of it running around the yard here.

Complete with a driving truck and passenger trolley with grass roller, so scope there for some useful income from your local cricket club.
