Mike5.56 - I have a 990 and am 6'-1" and ~240lbs. No issues whatsoever with the size of the deck; controls; ergonomics; etc.... Only time I've had problems is when I get lazy and let my right knee start operating the FEL joystick....quickly learned not to nudge it and doing fine now. I opted for the 990 to get great power in a smaller package for my 34acres and xmas tree farm. Also went with a LX5 cutter which is narrower for manuverability in the trees. You can also add rear hyraulics to operate a chipper or other implements.
Do not buy any other CUT until you get a chance to sit and operate a 990. Living with regret is a terrible thing...........Good luck
