As far as I know, the 425 sounds like the machine you want, I don't know that Deere has a provision for rear hydraulics though. The 3 point hitch on those use the mower deck lift cylinder
If you are going for the 445 why not step up to the 455 that is a diesel? 425/carb, 445/EFI, 455/dieselIf you are looking at a 425, you might want to consider the 445 which is basicly the same tractor. The reason I say this is because 445 is EFI, electronic fuel injected, which is more fuel efficient and no points to worry about.
