I run the exact same setup, and have the same experiences. When I till full depth (with the feet removed), it will bog my 2520 down in our garden. The 2720 is I believe 2 more HP, so the 65" maybe too much. But if the price is right, you can always go SLLOOWWW.I also run a 60" King Kutter on my 2520. Soil conditions make all the difference, sometimes its too much, others it just plays with it. :trink39:
