It has just enough on its own so I chipped it and now it rolls right along. The 3310 pulls easier than a 5710 because of the way the packers are. I really like the 3310 thought setting depth would be a pain but set it for peas then raise it for wheat,canola,flax. I can do it alone in about 20 min. A 9520 should have plenty. My neighbor pulls 65' of 5710 with a 6450 and twin 2000 NH3 with a 9520.
