The disclosure relates to an autonomous apparatus, moving and performing preset work in a defined working area, the autonomous apparatus including an energy module supplying energy to the autonomous apparatus, a motor, a sensor circuit, and a control circuit, the motor obtaining the energy from the energy module, to drive the autonomous apparatus to move and/or work in the working area, the sensor circuit detecting working parameters and environmental parameters of the autonomous apparatus, and transmitting detection results to the control circuit, the control circuit controlling the operation of the motor according to a signal transmitted by the sensor circuit, where the motor is a sensorless brushless motor, and before the motor rotates, the control circuit measures a resistance value of the motor, and estimates, one the basis of the resistance value of the motor, a rotor position of the motor, so as to control the operation of the motor.

A system for supplying electric power to components of an agricultural harvester may include a power storage device and a first agricultural harvester component. The system may also include a first bus electrically coupled to the power storage device and configured to supply electric power at a first voltage to the first agricultural harvester component. Furthermore, the system may include a second agricultural harvester component and a second bus configured to supply the electric power at a second voltage to second agricultural harvester component, the second voltage being less than the first voltage. Additionally, the system may include a converter electrically coupled between the first and the second bus, with the converter configured to reduce the first voltage supplied through the first bus to allow electric power to be supplied to the second agricultural harvester component at the second voltage via the second bus.

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.

A battery pack includes a main body, and a handle rotatably connected to the main body. The handle is integrally formed by a steel wire. A related garden tool includes a working head, a power driving device for driving the working head to work, and the battery pack.

A high-efficiency blade for a lawn maintenance tool includes a central axis and a mounting portion located on the central axis. The high-efficiency blade includes a cutting blade and a cutting blade sharpened leading edge. A cleaning blade is vertically offset from the cutting blade and is configured to mulch the associated clippings from vegetation and reduce an associated accumulation of clippings on an underside of an associated mower deck. The lawn maintenance tool can also include a deck having a separation distance between the cleaning blade and an underside of the deck. The deck can include an elevation change to vary the separation distance. The deck and high-efficiency blade can also include a forward or rearward tilt.
