Agricultural vehicle having a pivotable cab

1. An agricultural machine, the machine comprising:

a main frame;

a front coupling provided on the main frame for releasably attaching a work implement to the agricultural machine; and

a vehicle cab for housing an operator,

wherein the vehicle cab is mounted to the main frame via at least one hinge coupling, the hinge coupling having an axis of rotation transverse to the direction of travel of the agricultural machine such that, in use, the vehicle cab is pivotable about the axis of rotation relative to the main frame, to provide an operator with a view of the front coupling and/or a work implement attached thereto;

a controller arranged to control the pivoting of the vehicle cab about the axis of rotation, wherein the controller is configured to control the pivoting of the vehicle cab in response to the controller detecting an operation is being performed to attach or detach a work implement with the front coupling.

2. The agricultural machine of claim 1 , wherein the agricultural machine comprises a combine harvester or forage harvester.

3. The agricultural machine of claim 1 , wherein the vehicle cab is mounted to a support frame, wherein the at least one hinge coupling is provided on the support frame.

4. The agricultural machine of claim 1 , wherein the agricultural machine comprises at least one actuator arranged to control the pivoting of the vehicle cab about the axis of rotation.

5. The agricultural machine of claim 4 , wherein the vehicle cab is mounted to a support frame, wherein the at least one hinge coupling is provided on the support frame, wherein a first end of the at least one actuator is coupled with the main frame, a second end of the at least one actuator coupled with the support frame.

6. The agricultural machine of claim 5 , wherein the first end of the actuator is hingedly coupled to the main frame, and the second end of the actuator is hingedly coupled to the support frame, to allow the movement of a first end of the actuator through an arc as the vehicle cab is pivoted.

7. The agricultural machine of claim 4 , wherein the at least one actuator comprises a linear actuator, wherein the linear actuator is a hydraulic cylinder.

8. An agricultural machine, the machine comprising:

a main frame;

a front coupling provided on the main frame for releasably attaching a work implement to the agricultural machine;

a vehicle cab for housing an operator, wherein the vehicle cab is mounted to the main frame via at least one hinge coupling, the hinge coupling having an axis of rotation transverse to the direction of travel of the agricultural machine such that, in use, the vehicle cab is pivotable about the axis of rotation relative to the main frame, to provide an operator with a view of the front coupling and/or a work implement attached thereto;

at least one actuator arranged to control the pivoting of the vehicle cab about the axis of rotation, wherein the at least one actuator comprises a linear actuator, wherein the linear actuator is a hydraulic cylinder; and

at least one hydraulic accumulator coupled with the at least one hydraulic cylinder, the at least one hydraulic accumulator acting as a damper for the hydraulic cylinder to reduce vibrations of the vehicle cab.

9. The agricultural machine of claim 8 , wherein the agricultural machine comprises a controller arranged to selectively couple the at least one hydraulic cylinder with the at least one hydraulic accumulator.

10. The agricultural machine of claim 9 , wherein said coupling is responsive to an initiation of a road transport mode of the agricultural machine.

11. The agricultural machine of claim 8 , wherein the agricultural machine comprises a controller arranged to control the pivoting of the vehicle cab about the axis of rotation.

12. The agricultural machine of claim 11 , wherein the controller is configured to control the pivoting of the vehicle cab in response to a user command to pivot the vehicle cab.

13. The agricultural machine of claim 11 , wherein the controller is configured to control the pivoting of the vehicle cab in response to the controller detecting an operation is being performed to attach or detach a work implement with the front coupling.

14. The agricultural machine of claim 1 , wherein the agricultural machine is provided with left and right hinge couplings provided at left- and right-hand sides of the vehicle cab.

15. The agricultural machine of claim 1 , wherein the agricultural machine is provided with left and right actuators provided at left- and right-hand sides of the vehicle cab, the left and right actuators arranged to control the pivoting of the vehicle cab about the axis of rotation.

16. The agricultural machine of claim 8 , wherein the agricultural machine comprises a combine harvester or forage harvester.

17. The agricultural machine of claim 8 , wherein the vehicle cab is mounted to a support frame, wherein the at least one hinge coupling is provided on the support frame.

18. The agricultural machine of claim 17 , wherein a first end of the actuator is hingedly coupled to the main frame, and a second end of the actuator is hingedly coupled to the support frame, to allow the movement of a first end of the actuator through an arc as the vehicle cab is pivoted.

19. The agricultural machine of claim 8 , wherein the agricultural machine is provided with left and right hinge couplings provided at left- and right-hand sides of the vehicle cab.

20. The agricultural machine of claim 8 , wherein the agricultural machine is provided with left and right actuators provided at left- and right-hand sides of the vehicle cab, the left and right actuators arranged to control the pivoting of the vehicle cab about the axis of rotation.
