    I have a older Fisher plow. The trip spring mounting tabs on the trip edge are worn down to the point one trip spring fell out. Do I have to make new mounting tabs or can I get the from fisher? It is mounted on a 86 F250. I run in in the bottom hole to keep the tabs from hitting the ground. The cutting edge is worn down only 1/2". I know 3 other people with the same problem. Is this common?

    Common problem on older Fishers. The quick and dirty cure is to lay an old bolt or other piece of round stock along the worn edge and weld it. Otherwise, it's just a piece of flat stock with a hole punched in it. Cut the old one off as clean as you can, and weld on something that looks the same, only not worn off. If you don't weld yourself, any local welding shop has probably seen this before, and can fix it for you.

    If the tabs are still wearing off with the plow mounted in the bottom hole, and a relatively new cutting edge, either the mounting points on the truck are too low, or the plow itself has been tweaked, and the trip edge is coming too far forward in the untripped position.

    Thanks for the info guys. I might try the spacer deal. I am taking the trip edge apart on Wednesday. my friend orders high carbon steel cutting edges custom made from a local steel shop. I am going to go from the standard 1/2" thick x 6" wide edge to a 5/8" or 3/4" X 8" edge. That will hold the blade up higher so it won't hit and the thicker steel won't wear out as fast. I hope that will work.

    It sound like all the pins in your base angle are worn along with all the ears. I would replace the whole moldboard.
