Here is a video. I switched to a different way to upload video, it only took 5min to upload but quality is poor. I'm still trying to figure it out

. But some video.
I did bring the tractor over and tilled up the grass. Only one pas with the tiller to just break the sod up. It is still tough to push. Chunks of grass are sometimes harder to push than rock. And the tracks don't slip but hit some small rock every once in a while when it appears to skip. New tracks and sprockets were hiding up well, dirt was pushed into tracks and still didn't foul them. Happy so far.
