Collection, Preservation and Display of Old Lawn Mowers

CULVER G.A.

An Iowa, USA inventor and, in 1909, patentee of a lawn mower in which the blades of the cutting cylinder were made in the form of arcs of an ellipse, the bottom blade being shaped to that of the main blades to give a shearing cut. As far as is known, no mower was ever mass-produced using this principle.
