In the middle of 1909 the British company “Richard Hornsby & Sons” has developed one of the latest technically advanced machines of the time – a tractor with chain-track. The new machine was built to haul coal for 40 miles from the company’s coal mine in the creek near the town of Dawson, Yukon. The supply of coal was to provide the ability to run a thermal power plant in Dawson, as well as meet the needs of residents to heat their homes with coal. The steam tractor worked on coal, which carried it itself.
The Englishman Steve Baldock built an amazing and fully operational 1/3 scale model of the Hornsby chain steam tractor and presented it at the Lincoln steam fair in 2008. It took him 7000 hours in the course of 8 years to build it. This scale model has a weight of 1.3 tons, and works at pressure of 170psi. The tractor is driven by a compound engine while the gears provide no less than 8 speeds.
