It now runs on  air, is slightly less assembled than it was two years ago (having been taken  apart for painting) but has all bits to finish off, along with a complete set of  build instructions. The description below is blagged shamelessly from the  archive, the pictures are new, taken this afternoon.\u003c\/font\u003e\u003c\/p\u003e  \u003cp\u003eA complete, new kit-build 4 inch scale Ruston steam tractor, about 90%  assembled with parts to finish, including assembly instructions for all stages  and boiler paperwork including initial hydraulic test certificate, welder's and  material certificates.\u003c\/p\u003e  \u003cp\u003eA diminutive engine in full size at only 3 1\/2 tons, the Ruston makes for a  similarly dinky model in 4 inch scale - it's more like a super-sized 3 inch  engine, although with the advantage of more height which means less crouching  over the controls.\u003c\/p\u003e  \u003cp\u003eSteel boiler, 120 psi working pressure, initial hydraulic test certificate  for 350 psi. Boiler fed by injector and mechnical pump with bypass, auxiliary  hand pump mounted on side of tender. Stainless steel grate. Single cylinder,  slide valve actuated by Stephenson's valve gear. Two speed transmission with  winch behind nearside rear wheel and tender-mounted fairleads.\u003c\/p\u003e  \u003cp\u003eAs with all kit-build engines, the parts benefit considerably from  sympathetic fettling on assembly and careful checking at all stages for free  running.\u003c\/p\u003e  \u003cp\u003eLength 46 inches\u003cbr\u003e  Height 36 inches\u003cbr\u003e  Width 20 inches\u003cbr\u003e  Weight 400 pounds\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019713958229,"sku":"3684","price":5950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3684-1.webp?v=1779906440","url":"https:\/\/stationroadsteam.com\/products\/4-inch-scale-ruston-tractor-stock-code-3684","provider":"Station Road Steam","version":"1.0","type":"link"}
