The load dampening system comprises an accumulator apparatus for receiving pressurised hydraulic fluid, wherein the accumulator apparatus is selectively connectable to the second boom actuator to dampen pressure fluctuations in the second boom actuator.

A boom lift machine (10) is provided which includes: a body (12); a boom (14) defining a longitudinal axis (A-A);a mounting arrangement (50) mounting the boom to the body; and a lifting unit (54) extending between the boom and the mounting arrangement. The boom is pivotably connected to the mounting arrangement at or proximate a first end (16) of the boom. The mounting arrangement is configured such that in response to actuation of the lifting unit, the boom is pivoted to raise or lower a second end (20) thereof, and the boom is translated relative to the body. The boom lift machine also includes a counterweight mass configured to counterbalance a tipping moment of the boom lift machine. The counterweight mass is configured to translate with the boom.

A working machine comprising:an operator station; andan operator seat located at the operator station;the operator station comprising controls for moving the working machine via the ground engaging propulsion structure and working arm controls for controlling movement of the first working arm relative to the body;the operator seat being moveable between a first position and a second position;a display being positioned at the operator station and within the operator's field of vision when seated on the seat in the second positiona further display being positioned at the operator station and within the operator's field of vision when seated on the seat in the first position;the working machine being configured such that at least when the seat is positioned in the first position at least one of the following is displayed on the further display: a drive state of a transmission of the working machine, a steer mode of the working machine, a wheel drive state of a ground engaging propulsion structure (2WD/4WD), a steer position (wheel alignment state) of a ground engaging propulsion structure;the working machine being further configured such that at least when the seat is positioned in the second position at least one of the following is displayed on the display: a drive state of a transmission of the working machine, a steer mode of the working machine, a wheel drive state of a ground engaging propulsion structure (2WD/4WD), a steer position (wheel alignment state) of a ground engaging propulsion structure.

Disclosed is an excavator comprising: a ground engaging structure comprising a pair of track assemblies for propelling and steering the excavator; a rotatable superstructure mounted to the ground engaging structure; a working arm mounted to the rotatable superstructure, the working arm comprising one or more hydraulic actuators arranged to operate the working arm; a hydraulic pump in hydraulic flow communication with the one or more tracks and/or the one or more hydraulic actuators; a hydraulic tank connected to the hydraulic pump; at least one electric motor configured to drive the hydraulic pump to provide a flow of hydraulic fluid to propel the one or more track assemblies and/or operate the hydraulic actuators; at least one battery for providing electrical power to the hydraulic pump; and, at least one electrically operated fan configured to provide a flow of cooling air onto the hydraulic tank to cool the hydraulic fluid therein.

A start-stop system 100 for a working vehicle is provided. The start-stop system comprises a body 102; a push button 104 configured for linear movement relative to the body between a first button position and a second button position; and a rotatable sleeve 108 positioned radially outboard of the push button and configured to rotate between a first sleeve position and a second sleeve position. The start-stop system is configured to transition to an enabled state when the rotatable sleeve is moved from the first sleeve position to the second sleeve position. The start-stop system is configured to activate a prime mover of the vehicle when the start-stop system is in the enabled state and the push button is moved from the first button position to the second button position. The rotatable sleeve is biased to automatically return from the second sleeve position to the first sleeve position.

A control system for a working machine is provided, wherein the control system is configured to: obtain or determine a guidance path, wherein the guidance path defines a path to be tracked by the machine; obtain or determine an acquisition path, wherein the acquisition path defines a path for the machine to follow in order to position the machine to track the guidance path; and direct the machine to follow the acquisition path, in order to position the machine to track the guidance path.

A stabiliser assembly may comprise a housing comprising first and second stabiliser leg mounts arranged at or near opposing ends of the housing, and a mounting body connected to the housing, said mounting body comprising first and second mounting plates each comprising first and second actuator mounts, said first and second mounting plates being arranged to oppose each other such that the first actuator mounts are substantially aligned and the second actuator mounts are substantially aligned.

The present invention relates to a control system (18) for a working machine (10), wherein the working machine is configured to be fitted with a front implement (24) and/or a rear implement (26). The control system is configured to: obtain or determine a guidance path (28), wherein the guidance path defines a path to be tracked by the machine (10). Based on implement information, the control system is configured to obtain or determine an acquisition path (30) that is derived an implement acquisition path (29a, 29b). The vehicle is controlled to move along said acquisition path in accordance with the implement information, in order to position the machine to track the guidance path.

A working machine, comprising: a ground-engaging propulsion arrangement; a body mounted to the ground-engaging propulsion arrangement, the body comprising an operator station; a plurality of assignable controllable elements; a configurable foot pedal in the operator station for controlling a selected one of the assignable controllable elements; an input device arrangement; and a controller in communication with the configurable foot pedal and the input device arrangement. The controller is configured to: receive a selection input from the input device arrangement; assign any one of the assignable controllable elements for control by the configurable foot pedal based on the selection input received from the input device arrangement; receive a control input from the configurable foot pedal; and control the assigned controllable element based on the control input received from the configurable foot pedal.

Disclosed herein is a working machine comprising: a ground engaging structure for providing propulsion over a ground surface; a chassis mounted to the ground engaging structure; an operator cab mounted to the chassis; a gas engine for providing propulsive power to the ground engaging structure; at least one storage tank for storing gaseous fuel for the gas engine; and, a purge valve for removing gaseous fuel from the at least one storage tank.
