I just purchased a 1967 Wards Squire 10. It came with a 42in mower deck that has not been used in years. The belt is good and all three blades turn freely. Is there maintenance I must do to this deck? There are no grease fittings for the blade bearings/spindels. I can't imagine running this mower without doing some kind of lubrication. Please see the photo of the tractor and deck.
