摘要： A self-propelled work machine, in which the load of the work unit increases according to an increase in the travel speed. The self-propelled work machine includes electric motors for driving the travel units, an engine for driving the work unit, a work drive instruction unit for instructing the work unit to turn on, and a control unit for controlling the electric motors. The control unit reduces the actual speed of the electric motors by using PID control so that the actual rotational speed of the engine returns to a reference rotational speed when the actual rotational speed of the engine falls below the reference rotational speed in the state in which the work unit is turned on by the work drive instruction unit. The reference rotational speed is a reference value used when the work unit is driven by the engine.

摘要： A working machine having a working part driven by an engine and a transporting part driven by an electric motor. The rotation of the electric motor is controlled by a control part. The speed of the engine as of when the working part is brought to a working state by a work on/off switch being turned on is taken as a reference speed, and a correction coefficient corresponding to this reference speed is taken as an upper limit value. A correction coefficient corresponding to the present speed of the engine is determined. A required acceleration set in correspondence with the size of the actual travel speed of the transporting part is multiplied by the determined correction coefficient to correct this required acceleration. The control part acceleration controls the rotation of the electric motor in accordance with the corrected required acceleration.

摘要： An electric working machine having an electric motor and batteries for providing power to the motor is provided. Power for charging the batteries is provided to the working machine through a connector. A key member is provided which comprises a key body having one end for insertion into and removal from a switch, and an operation portion which is integrally or removably provided at the other end of the key body extending sideways from the key body. The connector is positioned to the side of the switch at a location where it is covered by the operating portion of the key member at a turned position of the key member when the switch is in a first state, such that the connection of the connector with an external power source is made impossible. Such arrangement ensures that a simple structure having a substantially reduced number of parts is used, to supply the electric power to the electric motor and it is impossible to charge the batteries when the switch is in one state, and it is impossible to supply the electric power to the electric motor and it is possible to charge the batteries when the switch is in another state. The switch can be switched from one state to the other state by a simple operation.

摘要： A self-propelled working machine has a pair of transporting parts, a working part, an engine for driving at least the working part, and a main switch for turning the engine on and off. A locomotion preparation switch produces a command for moving the transporting parts when turned on and produces a stop command for stopping movement of the transporting parts when turned off. A locomotion speed setting member orders a target locomotion speed of the transporting parts. A work switch switches the working part on and off. A control part stops the engine when a first condition that the main switch is on, a second condition that the locomotion preparation switch is off, a third condition that the transporting parts have stopped moving and the target locomotion speed ordered by the locomotion speed setting member is zero, and a fourth condition that the work switch is off, are satisfied.
