Almost the entire line of tractors is interchangable between Case and New Holland as they are the same company. Its like Ford/ Mercury. Same cars, different grills. But Ford has the Mustang while Mercury doesn't and Merc use to have the Cougar but Ford didn't. The TT line from NH does not have a Case-IH counter and the JX line does not have a NH counter (except I think the JX1075U series or whatever letters they are that are the TN clones).
