Oliver replaced the Row Crop 60 with the all new Model 66 in 1949. It was one of the new models added to the Oliver Fleetline series. The 66 featured a strong, four-cylinder engine with higher compression ratio, higher engine speed at 1600 rpm, and increased power. This little tractor could deliver 25 hp. on the belt and 21 hp. on the drawbar. Other features included six forward speeds ranging from 2.5 to 11.5 mph. Direct Drive Power Takeoff, controlled by a separate clutch, allowing power takeoff machines to be operated even when the tractor was not moving. And, Hydra-Lectric, an electric hydraulic lift system which provided easy fingertip control of attached implements. The Row Crop 66 was available in gasoline, kerosene and LP gas models and remained in production until it was upgraded to the Super 66 in 1954.
