250XP, 110hp 4BT, I think the tach showed around 3500 hours the one and only time I got it to work for 10 seconds, this was 3 years ago and I know this is atleast the 2nd tach this chipper has, so its safe to assume its got over 5000 hours
I've only had 3 surprise issues out of it, all 3 were my fault for a lack of maintenance, 2 blown hoses and the anvil fell out one day, just slipped my mind to check the bolts holding it and noticed when I heard a loud clicking sound while it was running, that was almost really bad, I check those multiple times a day now
right now I'm doing the hydraulic pump, reversing valve, might do the crush cylinder valve also, welding up lots and lots of cracks, and planning to add a pyrometer and boost gauge so I can turn the pump up a little bit safely because 110hp just isn't enough, as much as I love this chipper and think it chips great, another 50-60hp and working hydraulics wouldn't hurt on crane jobs
