A blade control assembly for a lawnmower can include a controller configured to selectively transition between a sleep mode and an operational mode. The controller can be configured to transition from the sleep mode to the operational mode when the controller receives a first ON signal. The controller can be configured to cause a power source to transition from an idle state in which a blade of the lawnmower is stopped to a driving state in which the power source rotationally drives the blade when the controller receives the first ON signal and a second ON signal. The controller can be configured to cause the power source to stop rotation of the blade and cause to power source to transition to the idle state after the second ON signal terminates, and can be configured to transition from the operational mode to the sleep mode after the second ON signal terminates.

The invention provides a mower, which comprises a battery package assembly and a frame for bearing the battery package assembly; the battery package assembly comprises a battery package and a fixing plate, the battery package is fixed on the fixing plate, a plurality of first pulleys are arranged at the bottom of the fixing plate, and the first pulleys are distributed along the installation direction of the battery package assembly. The frame comprises a supporting surface, and the first pulleys are supported on the supporting surface. The battery package assembly of the lawn mower moves on the supporting surface in a rolling mode, generated friction force is small, and convenience and labor saving can be achieved for the mounting and dismounting processes of the battery package assembly.

A working machine according to one aspect of the present disclosure comprises an operation rod, a leading end unit, a rear end unit, and a drive permitter. The operation rod is configured to be transformable between an extended state and a non-extended state. The leading end unit is provided at one end of the operation rod. The leading end unit comprises a motor configured to drive a working element. The rear end unit is provided at the other end of the operation rod. The rear end unit comprises a controller configured to control driving of the motor. The drive permitter is configured to permit driving of the motor when the operation rod is in the extended state and not to permit driving of the motor when the operation rod is in the non-extended state.

A lawn mower includes a drive source for driving a cutter blade, flaps, a grass clippings container, a grass clippings container weight detection unit, a travel distance detection unit, and a control unit. The control unit determines a change amount of weight of the grass clippings container detected by the grass clippings container weight detection unit over the elapsed time period from the time when detection of travel distance of the lawn mower is started by the travel distance detection unit to the time when travel of predetermined distance is completed, and implements control in a manner that the rotation speed of the drive source and the flap angle of the flaps are adjusted in accordance with the change amount of the weight.

A lawn mower includes a housing, a drive source, flaps, a grass clippings container, a grass clippings container weight detection unit, an internal pressure detection unit, and a control unit. If it is determined that a first condition where a change amount per predetermined fixed time of the weight detected by the grass clippings container weight detection unit is below a weight change amount reference value and a second condition where a change amount per predetermined fixed time of the internal pressure detected by the internal pressure detection unit has increased to a internal pressure change amount reference value, are satisfied, the control unit implements control to place the flaps in a substantially horizontal state.

A lawn mower includes a drive source for driving a cutter blade through a rotation shaft, a flap provided for the cutter blade in a manner that the flaps have a flap angle changeable along a horizontal line which is perpendicular to the rotation shaft, an actuator for controlling the flap angle of the flaps, a control unit for controlling the actuator, and a blade switching unit for switching the cutter blade between an operation state and a stop state. When the control unit determines that a stop switch signal has been received from the blade switching unit, the control unit controls the actuator to increase the flap angle of the flaps.

A control unit of a lawn mower performs switching control for switching operation between a first control mode and a second mode. In the first control mode, during rotation of an engine at a first reference rotation speed, in the case where a change amount of rotation speed of the engine per unit time has exceeded a reference speed change amount, the rotation speed is maintained at a second reference rotation speed, and an flap angle is increased. In the second control mode, during rotation of the engine at a second reference rotation speed, in the case where an opening angle of a throttle valve has fallen below a reference opening angle, the rotation speed is maintained at the first reference rotation speed, and the flap angle is decreased. The second reference rotation speed is higher than the first reference rotation speed.

A lawn mower includes a housing with an opened bottom, a hollow shaft extending in a vertical direction of the housing and including a lower end positioned within the housing, a cutter blade, flaps provided for at least part of the cutter blade in a manner that the flaps have a flap angle changeable along a horizontal line, an actuator for outputting an output to control the flap angle of the flap, and a transmission mechanism accommodated in the hollow shaft for transmitting the output of the actuator to the flaps.
