Abstract
An electric lawn mower and power cord combination in which the power cord has a central portion that is self-coiling. This central portion of the cord comprises the predominant length of the cord, and is constructed with an elastic memory, so that, when in its relaxed state, it automatically coils itself into a continuous spiralling helix that is too large to pass under the electric lawn mower. A cord grip is also disclosed that locks the cord to a stationary object to prevent the cord from inadvertently becoming disconnected during use.
