I have about 8 hours on my tractor and have lost a 3 point lower connector pin for my rotary cutter and a pin on the upper hook on my quick hitch. My dealer does not even stock these items! The QH hook has a cotter pin holding it on and the lower pin has a pin linch to hold it on. I figure that these are items that are commonly lost. I'm stunned that the dealer doesn't carry them. I ordered from Messick's as they are easier to order from and the price when shipped is about the same as the dealer 14 miles away. Is there a trick to keep these type items from coming loose?
