I paid $6,500 at Chappel Tractor in Milford. RN Johnson in Walpole also carries them, but at a much higher price. Salsco just came out with a smaller 3 pt version this year, its not even on the web site yet. Chappel normally keeps both in stock.
Salsco's web site is
www.salsco.com. Be warned, it is even worse than Deere's and Kubota's site. For instance, to find the 826, go to "Products, then "Tree", then "
Chipper, Models 8625, 8630 & 8633", scroll to the bottom and them click on "3-Point Hitch
Chipper". Your best bet is to take a look at one in person - everything on it is very heavy duty.
The problem I had with looking for chippers is that none of the dealers will demo them. I had previous experience with a little one, but none with anything like this. I called Salsco directly last year and they invited me to a farm show where they were giving demos. I had a schedule conflict, but I think that would have been worthwhile.
