A most unusual engine based on a portable of which a few were built by
William Foster & Co. Ltd in 1901. It is a single cylinder and although large
in scale is a very easy machine to build. It is chain driven and has one road
speed. There is a dog clutch fitted to the right hand side of the crankshaft
to disengage the drive for threshing, wood sawing and rope hauling. A steam
pump is fitted to the left side of the belly tank. No differential is fitted as
standard, but this can be fitted as an optional extre if required.
If you are wondering why it is called a rope hauling engine, a rope is taken
offthe bottom of the winding drum, round the pulley under the belly tank,
and out of the right-hand side, similar to a ploughing engine, hence it's name!
