I'm about to go nuts trying to get some dicamba stunted beans cut. It's an 84 L3 & I'm constantly plugging the feeder beater. The slip clutch is properly shimmed with 6 springs.It has a St. John's enclosed cylinder & 9 bar concave with about 1300 acres on it . Bars look very good. Running 3/8" cylinder gap at 600 rpm. Auger is up & all the way forward: reel as low as possible and back to auger.Beater fingers are about 1" off bottom in the middle position. Would it help to raise the beater and maybe retract the fingers sooner(all the way clockwise)? Also, does anyone know what bars are used on the St. John's cylinder? The left & right bars are 18" long with 3 holes & look like forward & reverse bars off rotary. The center one is 13" long with 2 holes. I can't find anything like this. I thought the paper that came with it said to use R62 bars, but parts don't show anything like my center bar. Any ideas? The bars are narrow spaced & I would kike to use wide spaced. Maybe help feeding? Just do corn & beans. Old Gleaner is doing an awesome job except for those shorties! Thanks for your help.
