What is preventing it from moving is in the previous pictures. Metal on Metal not allowing it to move any further. I am going to take a hammer to it this morning to see if i can bend the metal enough to just get it in. Old ride-on something may have moved over time. (started typing this this morning)

Okay have just got my brain back online and have now removed the entire drive system. Far easier than i thought, would have made my life so much easier over the last few days.

More pictures to come
