A lawn mower includes an internal combustion engine, a rotary tool driven by the internal combustion engine, an electric motor coupled to the internal combustion engine and configured to start the internal combustion engine, a receiving port mounted to the internal combustion engine, an energy storage device configured to be selectively inserted into and removed from the receiving port without tools, a first user interface, and a second user interface, wherein the electric motor starts the internal combustion engine upon actuation of the first user interface and the second user interface.

Lawn mower starter system

Outdoor power equipment includes an internal combustion engine including an electric motor, a battery receiving port, a rechargeable battery removably attached to the battery receiving port, wherein the rechargeable battery is configured to power the electric motor to start the engine, an implement driven by the internal combustion engine, a release mechanism movable to an engaged position to put the implement in a ready-to-run condition in which the implement is ready to be driven by the engine, a run sensor configured to detect the ready-to-run condition, a switch actuated by the release mechanism, and a control module coupled to the switch so that the switch provides a signal to the control module when the release mechanism is in the engaged position and the control module turns on the electric motor to start the engine in response to the signal from the switch and the run sensor detecting the ready-to-run condition.

Starter system for an engine

An internal combustion engine includes a cylinder, an exhaust, a fuel tank, an engine cover, a power take off configured to drive an implement, an electric starting system including a starter motor, a battery receiving port, and a rechargeable battery removably attached to the battery receiving port, and an electric start control module including a switch configured to be actuated by a release mechanism configured to put the implement in the ready-to-run condition and a controller coupled to the switch, wherein the switch is configured to provide a signal when the release mechanism is in the engaged position, wherein the controller is configured to receive the signal, wherein the controller it configured to turn on the starter motor to start the internal combustion engine upon receipt of the signal from the switch and an input from a run sensor confirming that the implement is in the ready-to-run condition, and wherein the rechargeable battery is configured to power the starter motor to start the engine.

A lawn mower includes an engine, an energy storage device, a motor/generator including an output shaft, an engine coupling, wherein, with the engine coupling disengaged, the motor/generator drives the output shaft, and with the engine coupling engaged, the engine or both the motor/generator and the engine drive the output shaft, a mower blade, a power take-off clutch, and a control unit configured to implement a first operating condition in which the engine coupling is disengaged, the engine is off, and the output shaft is driven by the motor/generator, and configured to implement a second operating condition in which the engine coupling is engaged, the engine is on, the output shaft is driven by the engine or both the motor/generator and the engine.

Hybrid lawn mower drive system

A lawn mower includes an internal combustion engine, an electric motor configured to start the engine, a blade driven by the engine, and an assembly for stopping at least one of the blade and the engine. The assembly includes a brake mechanism, a release mechanism movable to an engaged position to release the brake mechanism, an interlock configured to selectively prevent the release mechanism from moving to the engaged position, and an interface allowing an operator to release the interlock to allow the release mechanism to move to the engaged position. The lawn mower further includes a switch actuated by the release mechanism and a control module coupled to the switch so that the switch provides a signal to the control module when the release mechanism is in the engaged position and the control module turns on the electric motor in response to the signal to start the engine.
