I had to replace the mower deck on my 7 year old tractor my son caught a buried pole cutting a lawn and the mount broke loose from the deck. So I called the local John Deere dealer to get a new deck. I bought home and went to install it. They replaced the the mounting steel angles with a modified eye bolt. Problem was the eyebolt part to mount on the deck support stud, was to thick, I called the local dealer back to confirm this was correct, yes it does not fit prefect you have to grind them down to get them to fit. so I thined them out on both sides to get the cotter pin to go in. Next I leveled the deck per their instructions. problem is it will not cut evenly. I double checked leveling three more times and it still will not cut level. Any ideas?
