Oliver Farm Equipment began producing the Model 66 row crop tractor in 1949, and it had a 6 year reign. This two-wheel drive tractor had a six forward-speed transmission with two reverse speeds. Farmers had their choice of either a gasoline-ran row crop tractor or diesel-ran standard tractor. Both Oliver-Waukesha engines were Vertical I-head engines with four cylinders.
A couple of big differences between the two tractors were the weight and compression ratio. The row crop 66 weighed in at 3,193 pounds, and the standard diesel model weighed 3,795 pounds. The gasoline engine had a compression ratio of 6.75 to 1, while the diesel engine had a ratio of 15.5 to 1. When comparing horsepower, the gasoline-powered 66 got a max belt power of 24.9hp, and the diesel-powered engine had 25.03hp.
The Oliver 66 was produced from 1949 to 1954. Serial numbers correlate with production year as follows:

1949: 420001 – 421588 | 1950: 421589 – 426010 | 1951: 426011 – 429770

I recently purchased what I think is a 1951 oliver standard 66. I can’t find a match on any web site for serial number to confirm this. Any one who is very knowledgable with these tractors please call me 613 213 1193. I am not very good on computer so would rather a call. I live in Spencerville Ontario Canada near St. Lawrence river. Across from Ogdensburg New York. My home number is 613 658 9038. Thank you. My son’s name is Oliver so that reason for purchase .
