JD450 Dozer Will not move 12 12 2021

The next day my John Deere 450C didn't want to move , it worked perfect the day before when I finally got it home . It worked fine when I bought it . So I started doing some research and this is what I came up with . 1...The free travel is critical . That's the left side 3/4 bolt . Hopefully you will have some more turns out of it . I was running short . So after I adjusted the pressure by adding a penny , then adjusted the left side bell housing throw out bearing stop ... ( I think that's what they call it ) to get 5 to 10 pressure change when you push about a 1/2 to 1 inch down on the clutch . what I think made it all come together was the free travel adjustment . I didn't have enough turns so I added 2 washers under the bolt going into the clevis . The first adjustment made it move fwd but but not in reverse . After adjustment completion she pushes great . I think there are several different manual writers and they call the same component by different names . I hope this helps someone without to much confusion . The 450 is a awesome little machine , but sometimes misunderstood . I noticed some of the dates on the videos were wrong , This camera defaults to 2020 whenever I turn it off , ... Why !!! I just don't know .
