I have a 6 1/2 ft KK angle frame disc i bought 4 yrs ago.I bent the frame on the front left side where the disc hanger attaches.Probably going too fast and hit a rock.I cut out a piece 13 in long,drilled new adjustment holes in it and spliced it back in.Then I got serious.Welded heavy 2 in angle on top of that to now have 2 in sq tube.Cut groves out so I can still adjust the angles.I shorten the top link so only the front gang cuts and drive slower when starting a new spot.Its slower but I only have small plots of 1 acre or less.
