I am getting ready to put the rear finish mower away for the season, and my pressure washer is already put away in the cellar for the winter. I washed the top of the deck with Simple Green and water, and most of the grime has come off. The only place that the water beaded up was under the plastic covers. Would I be wasting my time putting a coat of wax on the powder coat deck? Since I don't have any space under cover, I am planning on putting it on top of a stack of 3 wood pallets and then putting a plastic tarp over it. Would you change the gearbox oil before putting it up for the winter or when it comes out of storage next spring? Any other suggestions? thanks Dusty
