The bad is the Waukesha engine and cab if it has one.

The good is everything besides the engine and cab.



The hydraulics on the 55 series Olivers was 20 gpm closed center which is as good or better than everything else that was built at the same time including JD.



The tractor part of 1855/1955 Oliver later became the 2-85/2-105 White which had a Perkins engine in place of the Waukesha and was offered with a better factory cab.    The 2-85/2-105 Whites were very good tractors.
