US Patent 11910736 Electric power lawn aerator

An electric power lawn aerator is employed in use to care for lawns. The electric power lawn aerator is battery-powered, and includes a frame assembly, one or more non-driven wheels, a handle assembly, a powerhead assembly, a powertrain assembly, and a tine assembly, among other possible components. The powerhead assembly has one or more battery cavities and an electric motor. A battery, such as a lithium-ion battery, is received in the battery cavity(s) and powers the electric motor. The electric motor imparts rotational drive to the tine assembly by way of the powertrain assembly. The tine assembly punctures the lawn amid use of the electric power lawn aerator.
