摘要： A work vehicle has a boom assembly for a work implement that provides an improved sightline between the cabin and work implement. The boom assembly can be a dual function boom having a wishbone configuration with an elongated body supporting the work implement and at the other end having branch sections extending outwardly at acute angles with open space therebetween. A boom support arch can provide an elevated boom mount on which the boom can pivot about a boom pivot axis at pivots located on the branches of the boom. The boom support arch can have its own pivotal mounting connection to the work vehicle. Actuators, such as hydraulic cylinders, can be coupled to the boom and support arch to independently pivot the boom and the support arch with respect to each other and the work vehicle.
