i had a gleaner too, and when i wanted to go to 6-30's had a heck of a time finding a head that was any good, still have a good gleaner but bought a 1440 first, then a 1460, love both machines, can go out sooner in the morning and stay later at night with the rotaries. i still like gleaners they are good machines, but i have a case_ih dealer closer now. gleaner also has a good rotary combine. guess it depends on how far away your dealer is. and if they have a good selection of parts on hand.
