An arm assembly for a work vehicle includes an arm configured to rotatably couple to a chassis of the work vehicle. The arm includes a substantially vertical portion, and the substantially vertical portion is configured to support an implement. The arm assembly also includes a lift actuator coupled to the arm and configured to couple to the chassis of the work vehicle. The lift actuator is configured to rotate the arm relative to the chassis to control a position of the implement along a vertical axis. In addition, the arm assembly includes a support actuator configured to couple to the chassis. The support actuator is configured to engage the substantially vertical portion of the arm to support the arm against a horizontal load applied to the arm by the implement.

The arm assembly of claim 8, further comprising a controller configured to control the support actuator based at least in part on a position of the arm. 13. The arm assembly of claim 12, further comprising a sensor communicatively coupled to the controller, wherein the sensor is configured to output a signal indicative of the position of the arm. 14. The arm assembly of claim 8, further comprising a second support actuator having a first end and a second end, wherein the first end of the second support actuator is configured to couple to the chassis, the second end of the second support actuator is configured to selectively engage the arm to support the arm against the horizontal load, and the second end of the second support actuator is not coupled to the arm. 15. A work vehicle, comprising a chassis and an arm assembly, wherein the arm assembly comprises: an arm rotatably coupled to the chassis, wherein the arm includes a substantially vertical portion, and the substantially vertical portion is configured to support an implement;a lift actuator coupled to the arm and to the chassis, wherein the lift actuator is configured to rotate the arm relative to the chassis to control a position of the implement along a vertical axis; anda first support actuator coupled to the chassis, wherein the first support actuator is configured to engage the substantially vertical portion of the arm to support the arm against a horizontal load applied to the arm by the implement;wherein the first support actuator comprises a stop at a second end of the first support actuator, andwherein the stop is configured to selectively engage the arm to support the arm against the horizontal load. 16. The work vehicle of claim 15, wherein the chassis includes a first cavity, and the first support actuator is partially disposed within the first cavity. 17. The work vehicle of claim 15, further comprising a second support actuator coupled to the chassis, wherein the second support actuator is configured to engage the substantially vertical portion of the arm to support the arm against the horizontal load. 18. The work vehicle of claim 17, wherein the chassis includes a first cavity positioned on a first lateral side of the chassis, the chassis includes a second cavity positioned on a second lateral side of the chassis, opposite the first lateral side, the first support actuator is partially disposed within the first cavity, and the second support actuator is partially disposed within the second cavity. 19. The work vehicle of claim 15, further comprising a controller configured to control the first support actuator based at least in part on a position of the arm. 20. The work vehicle of claim 19, further comprising a sensor communicatively coupled to the controller, wherein the sensor is configured to output a signal indicative of the position of the arm.
