I pull a Kuhn 3150 10'2" trailed mower with my 5083E and it does fine in B3 at about 6mph. Also a 458 silage special. A friend of mine just bought a 6105D, I used it baling silage earlier this year and the only complaint I had was with the 9F9R PowerReverser, there was not enough gear options to find the right speed. That being said, I have no real issues with my 5E, basic cab tractor by todays standards but, still definitely comfortable and capable. I will say, if you do go with the E, make sure you get the larger tires (18.4-30) rears. It really makes the HP go a lot further IMO. Good luck!
