Can anybody clear up details on the 2655s, mainly horsepower. I've read 139pto, 169 engine. But also read 2455 is 139 pto also. Were the cabs optional on them all or only the early ones, I've bought one, but really like the open station ones but this one has a cab, anybody know of a open station that is a parts tractor? Did they come with 38 inch rubber? This one has 38s and hub duals, they look original but I figured 34s were a more common size at the time. Looking for a center link and a drawbar also, prob other parts to but don't have a list yet. Plan is to restore it sometime. Thanks.
