Abstract
Electric lawnmowers comprise drive units and mowing units disengageably coupled to the drive units. For example, a drive unit can be disengageably coupled to any one of multiple mowing units (e.g., rotating mowing units, reel mowing units) collecting forming a mowing system. For example, each of the drive and mowing units may be equipped with corresponding mechanical-engagement structures that are configured to be disengageably coupled. Each mowing unit is equipped with its electric motor (e.g., for rotating the cutting blades or the reel of that unit). The electric motor may comprise an electric connector, which is disengageably coupled to the drive unit's electrical wiring. In some examples, each mowing unit can also form a liquid disengageable coupling for circulating a thermal liquid between the drive unit and mowing unit, e.g., for cooling various components of the drive unit.
