Your question suggests that you are thinking that the engine manufacturer is different for the 422 vs the 425. My apologies if I am mistaken. The 425s up until around the Summer 2004 run of manufacture, did have the Kohler engine. Now, however, BOTH the 422 and the current generation 425 models use a Robin-Subaru powerplant. The Robin, imho, is a strong and reliable powerplant. To quote Jack Gawecki, who has been tuned in to the PT Forum and who posts here himself:
</font><font color="blue" class="small">( According to the EPA regulations we are requried to stand behind 3000 operating hrs. on the engine, but that doesn't mean that the engine will fail after this time. I was discussing severe wear of parts with a customer in Alabama that had our engine on another hydraulic application tractor. With over 6400 hrs. within a year and a half, he called me demanding warranty on the wear of rings and some other parts, I've declined it, telling him that he's definately is getting his money's worth.

The only shortfall as I see it with the Robin is the service network. However, under Jack's leadership, that has been expanding by leaps and bounds, especially over the last year or so. Bottom line, 422 and 425 both use Robin, so that should help to make choosing one easier, since engine manufacturer is no longer a factor.
Hope that helps...
