I took the MMM off for the first time this week and I have a question about the system used to lift the deck. When I took the deck off. The two arms that hook to the back are just hanging and move up and down when I lift the 3pt. Is there any way to lock them up so they don't hang down to the ground? I just took them off since I didn't see any other way. Didn't want them to get caught on something and bend since I was using the tiller. Thanks for any advice!!
