I have only had my tractor for a couple weeks and I noticed that the deck wouldn't lock in the TOP position. I looked around and noticed that the linkage that goes to the back of the tractor and has a bolt that you adjust to stop how far back the linkage can slide was broken. The end of it was bent and the bolt that was welded on was bent around and so not doing anything anymore. I tried to bend it back and that just broke the bolt off fully. Either I can try to bend the end back and then get someone to reweld the bolt back on or I can buy a new linkage (but I have no idea how much they cost). I am not sure if this is a high stress part that would be better new or if rewelding it would be ok.
