1974 Cub Cadet 129 rolls off the trailer

I picked up this Cub cadet 129 for 100 dollars. This is a short video of me getting it off the trailer with no one to help. It took 3 of us to push it onto the trailer due to its weight and the hydrostatic transmission relief valves were not relief'ing.
In future videos I will be getting this tractor running but also doing a soft restoration.
