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.

Abstract: A deck height control system for use with a mower that has a deck positioned at a first height and is configured to support a blade motor. The control system includes an actuator that may be configured to vertically displace the deck from the first height to a second height. A deck system module may connect to the actuator and be capable of signaling the actuator, during operation, to displace the deck a particular deck distance in a particular vertical direction necessary to achieve the second height. The deck system module may further have a deck height memory capable of storing information relating to deck displacement activity. A control may connect to the deck system module and be capable of signaling the particular deck distance and particular vertical direction to the deck system module when engaged by an operator. A battery-operated mower may include the deck height control system.

Abstract: A motor vehicle front section of a motor vehicle includes a first spatial region, a second spatial region formed separately from the first spatial region, a first cover that covers the first spatial region, and a second cover that covers the second spatial region. The first cover extends substantially over a width of the motor vehicle front section, and the second cover extends substantially over the width of the motor vehicle front section. The first cover is arranged in front of or behind the second cover in a vehicle longitudinal direction. An access is provided in at least one of the covers for at least one connection arranged underneath the cover.

Abstract: A wheeled platform has a base, a plurality of wheels, and a power supply. A connector extends from the wheeled platform. A motor assembly has at least one motor mounted on the connector to couple with a stroller. A controller assembly steers the stroller. The base includes an upper surface for supporting an operator. The base forms a wheel assembly for holding the wheels. The power supply sends power to the motor assembly through the control assembly to drive the stroller.
