In the spring of 1925, Fruit Growers Supply Company announced a major change in their logging operations. In April, the company sold some seventy logging horses, thus a major phase out utilizing horses and Michigan Big Wheels. The company replaced the horses with six Catepillar tractors, after having two in operation the previous year. The tractors were more efficient, as they could go in terrain the horses could not. Horse logging also required additional workers known as “swampers.” Their job was to remove any debris or vegetation that could result in an injury to the horses legs.
