Somewhere in the instruction manuals I read that you should keep the box and packing materials in case you need to return the item. The mower box is almost 12 cubic feet. I don't mind keeping it out on the front porch for a bit, but I don't want hang on to it for 90 days. Does anyone know, will Home Depot take the mower back without a box? I am sure I want to keep the mower, but just in case something happens, I don't want to hear you should have kept the box.
