I have a new Craftsman rear engine riding mower with a 30" deck, model 247.2900000, that now has 10 hours on it. The maintenance schedule says it is time to lubricate the deck spindle and idler bracket. The manual includes no photos that are of any help. Should I be looking for grease fittings? Should I be applying oil to these two items? Confused here. Any help would be appreciated.
