Good Morning, I bought the Wallenstein bxm42, cost $4235 CDN. I found the same machine in Iowa for $3900! I called the company to find out why and just got a runaround, seems the American way is to market stuff like this through distributors and not to sell to individual dealers by the manufactors. Got about 20 hours on it and am very satisfied. I can do about 90 cu ft of White Cedar chips in 1-1 1/2 hours. My tractor is a Kioti CK35hst and I would not go to anything smaller for this tool. 40hp would be better, but so far so good. I have not sharpened blades yet. Good Luck!! P.S. I'am originally from Sussex N.B. and I know it!!!
