A working machine with a working unit is configured to perform a work, comprising a battery and a control unit, wherein the control unit has, as operation modes, a normal mode in which the working unit is operable based on power of the battery, and a power saving mode in which the working unit is made inoperable by limiting some of functions, as compared with the normal mode, and power consumption of the battery is suppressed, as compared with the normal mode, thereby, it is possible to improve the usability of the working machine and to appropriately prevent the battery down of a working machine.

Working machine having multiple modes of operation

A control device according to the invention, comprises a first electrode, electrically connected to a power unit, that receives a first electric power from the power unit as charging power of a battery, a second electrode, provided to be able to be electrically connected to a predetermined power source, that can receive a second electric power from the predetermined power source as the charging power of the battery, and a rectifier element, arranged in an electric path between the first electrode and both the battery and the second electrode, so as to allow passage of the first electric power from the power unit to the battery, and to regulate passage of the second electric power from the predetermined power source electrically connected to the second electrode to the power unit.

Control device, battery unit, and work machine

The configuration includes: a motor for driving a driving wheel (rear wheel) provided to a body; a slip ratio calculating section for calculating a slip ratio while the lawn mower is traveling; a friction coefficient calculating section for calculating a friction coefficient of a ground on which the lawn mower is traveling; a determination section for determining whether the ground on which the lawn mower is traveling is a lawn based on a relationship between the slip ratio and the friction coefficient and a drive controlling section for controlling the motor based on a determination result from the determination section. This configuration allows suitable driving operability for both of a case where the ground on which a lawn mowers traveling is a lawn and a case where the ground is other than a lawn.

A work machine determines, when a request to restart an engine is made, whether or not a reason indicated by stop information stored in a memory is a reason related to locking of the work portion. The machine sets an operation mode of the engine and a work portion to a safe mode if it determines that the reason indicated by the stop information is a reason related to locking of the work portion. The safe mode is an operation mode for lessening damage resulting from causing the engine and the work portion to work during the work portion locked or damage resulting from an object coming into contact with the work portion during the engine and the work portion working.
