257 if you can ever get your hands on a old Brown brush cutter for a go price get it. It's a super HD bushog it's basically a hybrid half tree cutter half bushog. I bought a used 7' one probably ten years ago and it's the best implement decision I've ever made. The things is unbelievable if I can get the tractor over it the thing will cut it and if I can't I'll back into it but what makes it special is you can cut your front yard with it to. I don't think they make them anymore and I have a hard time keeping folks from borrowing it other then that it's amazing. I primarily use it behind my 5075e but it's all it wants it's almost a perfect fit for my 6330 and MF 6465 and will eat a 10' pine. I put a slip clutch on it years ago and it made a big difference. I'll make a video of it cutting and post it on here in a couple weeks. By the way I believe I gave $500 and an old 5' bushog for it just to use in nasty situations so I didn't tear up my good stuff and now I can't do with out it.
