Mamod Working Model Steam Roller (CHALLENGER)

Steam traction engine

Steam traction engine


This is a superbly realistic model of an early steam road roller. Open the boiler valve and use the supplied funnel to pore in some water. Put the valve back on. Place a couple of the solid fuel tablets (supplied) into the burner, light with a match and insert under the boiler. Wait a while for the boiler to build up steam. Give the steam whistle a little toot to see if the pressure is up. Then use the control lever to burst the engine into life. Drive belt can be removed to allow the engine to idle or power some apparatus. A wonderful live steam model.

The CHALLENGER has more sophisticated double action piston valve, providing more power and speed. 9.5 bore, 14.0 stroke. Displacement lubricator. Forward and reverse action by slip eccentric.
