I have a customer that does commercial cutting on a state contract and operates a 8' rotary cutter behind his 3525. I had told him an 8 footer was to much for the tractor so he bought the cutter from his local MF dealer. He tells me it works very well, and when the going gets tough the governer kicks in and the engine builds even more power. He operates the 8' cutter behind his 3525 and his 4110 and he is happy with both. I would go with the 6' cutter if I were you. Good Luck!
