Same here. Borrowed a 2 bottom moldboard plow once with a frame that had been broken and welded back together. I was just breaking a small garden plot and figured it would surely last through that.However, I have a problem borrowing things. I almost hate to do it because it makes me a nervous wreck to be in possession of and responsible for someone else's stuff.
I was wrong. :/
Plowed a few minutes and it broke in the same spot. Someone had run one bead around the break, with very little penetration.
I spent several hours tapering each side, aligning it, and welding it back to 100%. All for about 20 minutes worth of plowing.
For some reason, folks I've loaned stuff to don't generally have the same principles.
