This is one serious looking tractor. TractorData lists this weighing 16,500 lbs with 147hp engine. Funny, most data sheets you see list this engine as a 210hp base with up 435hp fully loaded. It also said the 3208 was a replacement for the Cat 3150 (here is one from another 2255 at the Rantoul show)
This 3150 is the same engine that was in the Steiger Super Wildcat. In the Series II Super Wildcat the 3150 and later the 3208 were used and both engines were listed as 200hp. The Series II Bearcat lists the 3208 at 210hp. From what I have found online it appears the 2255 was Nebraska tested with he first 3150, never the 3208. Do the later 2255's have more power?
