I have an older craftsman LT1000 , With pull pin in rear to put trans in neutral to roll by hand . This mower has set a few years ,last year could not get it in neutral had to lift rear end up to move .This year it rolls fine , but can't seem to get it to go in gear seems to grind and not grab . Drive .Not sure if low on rear end needs oil ?(no leaks ! ) or just set up from low use (need to break free some how?

Hi,
I think I would run the machine for a time to "loosen" up the parts.
Peace,
Clarke
