Sooo.... I have an older Cub Z-Wing, which is the Tank with a deck that folds up on the sides. I had released the Hydros to push it and then this season I went to mow the right side lever moves forward and back, but the left is stuck in the middle. I noticed there is slot on the arm mounts that attaches to a rod to the hydro on each side. The right side mount bolt is slightly behind the cut-out of the mount and the left side is in the slot. Are these adjustable? Any ideas? Pics below.
