First let me say that I have Pat s quick hitches on my 8N and my MF202 and I love them. But there are a couple things one should know when using them. The first one is this. When you lift the hitches under your implements lift pins, the wedge snaps into place so that the pin can t come up and out again. There is a sliding lock that swivels into place so that wedge can t possibly come up again. Once I get my mower hooked up, I put electrical ties around that sliding lock and the quick hitch body. I have had one of those lock holders swivel out of place but using the ties solved that problem.
The second thing is this. When you slip the quick hitch over your lift arm, you place the pin through the body and the ball of your lift arms. The pins provided have a hole in the pin for a cotter pin to keep the pin in the quick hitch. When I went to use my mower this morning, I noticed that the pin that goes through the hitch and lift arm was sticking way out. Nothing was through the other side of the hitch. This happened because there was no cotter pin holding that pin in there. I pushed the pin back in and put a new cotter pin in there.
I pulled the pin out of the other side and noticed that it was rusted so that s probably what happened to the pin on the other side. So, now there are two new pins in there. Near as I can figure those pins were probably three years old. If you use quick hitches, I would probably put new cotter pins in there every year. If you don t leave your tractors outside as I have to you shouldn t have any problem with rust. But just to be on the safe side, once you get your implement hooked up and remove your spreader bar, I would insert a lynch pin in those holes as a back up.
