Good luck with finding any parts for these plows. I bought a 4 bottom plow a few years back and it did the same thing. I welded the trips down and broke 2 of the trip mechanisms in the flat part. Made repairs on that and beefed it up a bit on all 3 as I took one share off and then broke a share completely off. Bearings for the coulter wheels and hub assembly are also impossible to find now. I had found a couple through my local Deere dealer, but they were no where close and were a couple hundred dollars each. Apparently these weren't very popular plows and all repair parts were discontinued. I didn't pay but $350 when I bought mine and I guess I've got my money worth out of it, but it's not really pleasant trying to use it because it's such a pain to keep making repairs to keep it going, even being a welder and mechanic for a living.
