A few years back I bought a 3 furrow trail plow. They had done some alterations on the crank that sets the back gauge wheel. Now I would like to restore it to its original condition. Unfortunately I don't know what model it is. It is on rubber with a rubber tire gauge wheel There is no hydrulics on it, though I have seen others with a cylinder instead of a lever arm. There are numbers on it, probably part numbers for that particular part. The tag is long gone. I would appreciate any help and if you need more information please advise.

               Thank You
