Oliver 77
Row-crop tractor · 1948–1954 · Gasoline
The Oliver 77 was the mid-size entry in Oliver's postwar Fleetline row-crop lineup, slotting between the smaller 66 and the flagship 88. Its Oliver-Waukesha six-cylinder engine, offered in gasoline, diesel, and LP-gas versions, made it one of the most versatile tractors of its era. Built at Oliver's Charles City, Iowa plant, the 77 became one of the company's best-selling models through the late 1940s and early 1950s.
