I considered replacing the meter but have never carried through with it. I actually don't pay much attention to that hour meter. I change the oil in it once a season nu matter the hours.
I know some forums complain if you bring up old threads, but not here. I have no problem with discussing and re-discussing an issue. I don't understand why other forums complain so much about the practice ...why keep the old thread if they are not there to be commented on and replied to?
..back on topic ... you have more hours on your 2005 model than I have on my 2002 model x595. The first few years I racked up lots of hours, then I got a ZTR for the mowing duties.
Nice tractor you got there. You must not use yours for mowing. I'm in the same ballpark for hours on my Kubota this year. Bush hogging does not add up the hours at all like mowing every week does.I've put a huge 30 hours on mine since I got it last April.
Even with splitting your time in Panama and CA.
Good job Al. 
We have a few other members who run a few head of horses. Hopefully they'll see your pics.
