How do you get your Massey Ferguson to shift out of reverse it is stuck in reverse?
If the trans is locked in one gear, and the stick refuses to
move, it has very likely jumped out of the shift selector rods. You
will likely have to remove the shift stick cross pin, to pull the
stick out, and manually with a long flat screw driver, shift all
rods to the neutral position. There are cut aways in the rods. The
neutral position should be when they are all in the same general
location so the stick can move between them. Test this by bumping
the starter, before replacing the stick.
