Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
Forward/Reverse linkage needs to be adjusted, best to raise rear of the tractor, unhook the f/r linkage, and start tractor, the transmission lever should move to the neutral position, then adjust the linkage to match the lever location.
I see question is still open, did you get the adjustment made?
