I noticed the used one on your website has only 5 belts, 3 wide and 2 narrow. The one I'm looking at has, I think 8 narrow belts. Is the difference just yours being a newer model? I've also heard talk aboult a couple of plates that you can bolt inside just above the drive roller that look like moon shaped hubcaps for a lack of a better discription. What are these for and are they worth it? Thanks, This Vermeer bales like a cadallic compaired to the IH8444 we have.
