I need step by step instructions for adjusting tracking. Mower was drifting to the left, and couldn't remember how a friend that works on lawnmowers showed me to do it. At one point, it just got to where it would make a circle, and when I put it in Park, it was still trying to go. With the mower on jack stands, I noticed a that one tire was moving faster than the other. I also discovered that the little rod that turns off the hydros was bent. I've straightened it back out, and it will be put back on first. Someone was adjusting the threaded rod that determines range of motion control lever. Gotten it all out of wack, so that would be the best place to start if anyone can help me please.
