I've busted the back bracket on my 750 a couple times - I'm not sure what is causing the problem . . . . Seems to give problems about every 900 to 1000 acres. Never had the problem, untill I had the rear cylinder repacked, as it was leaking.

This spring, after 300 acres, the rear main pillow block bushing, bracket on the drill frame broke a bolt and tore the bracket off the frame. Took half a day to rebuild that - it won't brack again. I'm afraid what may go now . . .
