Farm Pump Engine

    Perhaps the most unusual and successful engine ever made by Fuller & Johnson was the Farm Pump Engine.  This air cooled engine was designed by Frank D. Winkley in 1909;  He was the man who built the first oil cooled engine back in 1900.  The Farm Pump Engine was most unusual in both its design and operation.  It ran counter-clockwise and had two exhaust ports.  A muffler was used on the bottom exhaust port only.  Over 56000 engines were made from 1909 until the final days of operation in 1933.  While rated a 1 1/2 hp, the engine only developed 5/8 hp.  it was in the gear reduction where the rated power was achieved.  This highly adaptable engine was copied and reproduced by a number of other firms;  testament to its remarkable success.
