Got this about 4 years ago. 2 weeks ago the cotter pin fell out of the left bar that adjust the deck, seen that it was gone, installed another and had again cut the grass, seen it was scalping the left side, so attempted to adjust it. it does not seem to be adjusting as it needs to be & looks like rear of the deck is dropped. I cannot find my owners manual and need to figure out what is still broke there.
Pictures & such of the setup would help I believe or suggestions on what to look at, replace would be appreciated. I may have bent the deck as well, but it looks straight.
