Finish mower options

To me it doesn't look that bad.
But if you think it's bad, one trick is try spinning the shaft 180° on the shaft.

Ok, thanks. I thought the third video shows it looking pretty bad. I'll try spinning it 180 degrees and see what that does. I was also going to try it again this morning with grease as the splines were pretty dry from cleaning and handling. Unfortunately it wouldn't start - it turned over but was really sluggish. I tried a second battery and a jump start with the same result. I've now got a battery on charge overnight and will try again tomorrow. I kicked it and headed inside to watch the Aussies play Paraguay in the world cup - I'm not a soccer fan, but don't mind watching these games.

Could the sluggish to turn over also be caused by a starter motor on the way out....worn brushes, high resistance ?
