I have a 2004 MT855A. Few winters ago I was changing the hydraulic/tranny oil and noticed the charge pump had like 2 of the 6 bolts broke. I called dealer and they said there was an updated charge pump...recommend I changed it. I think the tractor makes more noise now than with the old pump with broken bolts.
