 Apart from threshing work, portable engines were used to drive corn-mills, centrifugal pumps, stone-crushers, dynamos, chaff-cutters, hay-balers and saw benches.They were even used to generate electricity for floodlighting at football matches, the first instance being at Bramall Lane, Sheffield in 1878.In general, the portable engine is hauled to the work area, often a farmyard or field, and a long drive belt is fitted between the engine's flywheel and the driving wheel of the equipment to be powered.
