The Oliver 880 was built from 1958 till 1963. They used the Waukesha 6 cylinder , 265 cubic inch engine which produced 55 drawbar hp. Gas or diesel engines were available. The 880 replaced the 88.Our 880 has what I think is unique, a power steering pump that is attached and driven by the generator. Our tractor is a wheatland gas model. The serial number is 85530 which means it is a 1960 model. Our 880 had a front end loader on it when we bought it. It has been removed. The tractor came from north of Winnipeg.
