I run an older 630 but very similar machine....belts, bearings and chains etc. Only one gearbox.
Ours was well used when we got it and needed lots of TLC.
PTO shaft failed on this one, the CV joint on tractor end, replacement shaft is over 1K. I now just run a regular yoke end :-( So probably worth checking the condition on that when deciding on what to bid.
Run it on 42 PTO HP fine..but more power wouldn't hurt.

I'll have to check on the pto, but I did see two tractor halves of a pto shaft with it (one on the pto and another tied to the pickup). Maybe the previous owner already had a pto problem with it. If I do manage to pick it up, I'll probably run it with my JD 2520 (one of the older new generation tractors, not the compact version) which is around 60 hp. Great to know I'll have plenty of power.

Thanks, Josh

Make sure they are 'in time'. That bsler probsbly has the same gearbox and pto setup as mine. I used the shaft off my manure spreader one time and it chattered pretty well, but got me finished as long as I didn't turn tight. But the yoke on the sliding section was out by 90 degrees. CNH wanted close to $200 for a new one, and mine was torn up pretty good. I wound up replacing it from the cross to the tractor with two new halves at a cost of about $140. CNH figures they are the only place to find parts.....
