Not sure whats going on with your lift but yes you SCORED. Looks like its in nice condition and the engine looks like a relatively recent replacement. As for the spindle, not all of them had grease fittings. It was probably just replaced at some point. There are not any aftermarket spindles I am aware of that will fit these decks. All the grease fitting does is allow you to fill the cavity between the bearings with grease. The bearings themselves are sealed.
