Here's an interesting question:
Do you think that a 440, with heavier final drives than a 420, could handle having a scarifier mounted onto the rear without busting the poor, old thing?
I have the opportunity to add my uncle's 440 to my dad's 420 (oh, no! the rampant machine collection disease is apparant!). However, I don't see much point in having another crawler/dozer on hand unless it were to have a power blade and a scarifier to make grading our mile-long driveway easier.
Up until this weekend, I was thinking about a getting a JD350c so equipped, not a 440. Then, my aunt mentioned that they were going to be selling off a lot of my late uncle's toys, and wondered if I might want the 440. I'm the only one in the family that has the machinery 'disease', you see.
Anyway, the thing is 800 miles away, and I can't see going after it unless I have at least half an idea that I can run the thing with a scarifier on it. Plus, I know this one has the manual blade, so there's yet another set of bits I'll have to come up with to make the 440 into what I have in mind - adding a power adjust blade.
I'm on the fence here, so what do y'all think?

p.s.
I forgot to add that my aunt is wanting $4k for the thing and that I'm uncertain as to it's current condition. It was in pretty nice shape the last time I ran it, which was about five years ago, and I don't think that my uncle used it much at all in the past few years. What worries me is that one of my ham-handed cousins might have used it!
