JD, I have the MX-5 and also have property in northern MN, and I have logged in over 40 hours of seat time cutting aspen thats about 18 months old and I think it works fantastic as long as you can avoid the stumps.
That is good to hear. I used my neighbors 60 inch swisher behind my jd buck.
All i did was break the trail into the food plot I am going to make. Let me tell you that little 14 hp swisher did all right. It was not very subtle going through that stuff. I was wearing hearing protection and it was pretty noisy, but the little mower did all right for making a trail. I did find a few stumps to avoid, but there was not too many. I hope I can dig those out with the 3520 fel.
