I have run Gleaners, John Deeres, Massey Fergusons, Case conventionals(960) IH conventionals, CaseIH rotaries, and been around Cat(lexion),and NH twin rotor machines. There is not a one of them that can not and will not do a good job is if properly set and operated. In the hands of a poor operator there again is not a one of them worth, well anyhow you get the drift. Put a good operator on the seat and even the worst one of the lot will do a good job.
