Abstract
A working machine including a ground engaging structure and a propulsion system for moving the working machine via the ground engaging structure. A body is supported on the ground engaging structure, and a working arm is connected to the body and has a carriage at one end for receiving an attachment. A control system is provided for selectively and variably oscillating the carriage.
Claims14
A working machine comprising:
- a ground engaging structure;
- a propulsion system for moving the working machine via the ground engaging structure;
- a body supported on the ground engaging structure;
- a working arm connected to the body and having a carriage at one end for receiving an attachment;
- and
- a control system for selectively oscillating the carriage, wherein the control system comprises:
- an actuator configured and arranged to selectively oscillate the carriage;
- an electronic controller configured to control the actuator;
- and
- a user input device in communication with the controller;
- wherein the user input device comprises an oscillation input configured to selectively transmit an oscillation signal to the electronic controller to indicate a desired amplitude and/or frequency of oscillation of the carriage, wherein the oscillation input is variable to alter the oscillation signal transmitted to the electronic controller, wherein the user input device further comprises a position input configured to transmit a position signal to the electronic controller to indicate a desired change of position of the carriage, wherein the electronic controller is configured to upon receipt of the oscillation signal selectively activate the actuator to oscillate the carriage at the desired amplitude and/or frequency indicated by the oscillation signal, the electronic controller is configured to upon receipt of the position signal activate the actuator to move the carriage as desired,
- wherein the position input comprises a control device that a user can move to indicate the desired change of position of the carriage, and there is a linearly proportional relationship between the desired amplitude and/or frequency of the oscillation and the position of the control device with respect to a neutral position of the control device.
