Wondering if anyone else had this problem.. Hooked up plow all good , the pins locked into place, Plowed , worked fine, Next day , plowed some more and heard a banging sound, got out and looked , only to find the plow half haging off of the truck !!! the pin hook thing popped off and the foot was slaming into the ground, Its all messed up now, jammed in.. But what happend ?? The only thing I could think of is some water got into the pin, froze and popped it out ?? is that possible ?? I guess anythings possible /??
