Just waiting until spring / summer I'm in no big hurry at the moment. I'm still deciding between a 422 or 425 not sure just yet. Still asking myself why I would need a 425 when the 422 seems to be able to do almost anything the 425 can do.
For my situation I really don't need the extra wheel torque or lift height. I don't have a lot of steep hills and I don't use it to mow or bush hog. The only sticking point in my mind might be the single ram versas the double ram and the durability. Other than that I'm sure either machine would be just fine.
You made the right choice, better to be safe on those hills no tractors worth getting hurt over.

It's just a shame you had to go through all of head aches with the leaks and other problems. That's why I won't buy used, at least not in a Power Trac. I figure they come with enough little flaws / bugs when there brand new. In the end you still have a fine capable looking machine there.
