Well, I was trying to do some maintenance on the mower, so I decided to check the grease levels in it, and any wear and tear. So i tried to pull the top off, and I can't get it off. I put it back on, and it didn't quite "fit" that well. After a little playing around i got it back on, but now it seems to be harder to shift. Also, I took the neutral detection- the thing that stops if the operator doesn't have it in neutral and leaves- and now it doesn't work. So much for trying to maintain the equip., Any suggestions?
