I also have a CIH 8575, bought it used 3-4 years ago, was told it had made 39K bales. Local baler service guy told me later that my baler showed more wear than another locally owned baler with 42K bales on.....maybe my baler baled cornstalks?

I haven't had any trouble with the monitor, everything else is fairly simple, just parts that you can watch move and figure out what it should be doing. We took the whole knotter assy off one winter and welded up the cracks and replaced all the wear parts, it's been good since. Replaced just about all the wear parts on the whole baler, I should be good for several/many years. Maize Corp is your best friend if you have one of these balers, they have parts that AGCO doesn't and ship quick, the guy on the phone will help you figure out what you need and don't need.

I experienced untold frustration trying to get a custom baler to show up when promised so I ended up buying a baler even though I couldn't justify the cost for the thousand or so bales per year I need.

Just hooked it on the tractor yesterday, going to take it to the field for the first time this year later today.
