Is this shed big enough for a riding mower?

At 10 by 16 feet it has the floor area for a riding mower plus tools, but check the door opening height and width against your mower before buying.

Does it need a foundation?

Yes. A steel shed of this size should sit on a level, solid base such as concrete or a prepared gravel pad, or the panels will not square up.

The galvanized steel and powder coat resist rust and corrosion, but cut edges and scratches should be touched up to keep moisture out.

Plan on two people. Owners report the panels are large and awkward, and the job takes a full day or more.

Yes, the doors are lockable, which is the main security advantage over open racks or a tarp.
