An example of a fire-extinguishing apparatus includes a plate member including a convex front surface configured to be exposed to fire, and a concave rear surface. The apparatus includes a handle member including a first end and a second end. The handle member is configured to push the plate member over the fire. A joint connects the first end of the handle member to the concave rear surface. In one example of using the apparatus, the apparatus can be placed on a location on a line of fire. By pushing the apparatus along the line of fire, the fire along the line can be mowed.
