Looking at upgrading my 4wd. Looking at a STX430 and STX 485, the hours are within 100hrs, specs are the same for options etc. The 485 is actually priced better than the 430. Looks like they are both a 12.9L engine. Don't need anything much bigger than 430hp. Will they both use the same fuel doing similar work? Will be pulling a 45ft airdrill.

sounds like one of those too good to be true deals, 23 gph at 450 hp getting real close to 20 gal/hp hour...can use the same operation to get at the other tractor, not accurate as per running until so many hours are used then head for the fuel tank but will show the difference in fuel consumption in relation to each other...Don't use that to compare colors or we all be in trouble...23 gph at 460 hp makes it much easier to see.

Sure?
Not familiar enough with CIH model #'s to say for sure but in NTTL they are different as long as I am picking the right tests.
And I'm not sure I'm.:confused:

Did they go from 15.0 Cummins to 12.9 Iveco in from 480 to 485?

485 had issues with the compound turbo set up around here, they are cheap used. On the up side 430 did not have the compound turbo.
