Working on a 2022 BX23S with 80 hours. Tractor will not stop when I lift off the pedal going in reverse, forward is fine. I did get a WSM manual and it shows to loosen the bolt on the bracket but is pretty vague on what to do after that. I marked where it is set at, loosened the bolt to the point it may fall out, but I could not get the bracket with the slotted teeth to move. I didn't want to remove the bolt, afraid everything would fall off or I would lose it's position completely. What is the trick or technique to move the bracket just a little? Thanks in advance for the help!
