Abstract: A boom segment is provided for a spray boom assembly configured to carry a spray system of a work vehicle. The boom segment includes a truss panel formed as a unitary structure composed of fiber composite material and configured to support components of the spray system. The truss panel includes a panel wall extending along a length of the truss panel and defining an upper beam, a lower beam, and an array of braces spaced apart and extending diagonally and seamlessly between the upper beam and the lower beam to define a series of truss openings therebetween and a plurality of rigidifying ribs formed integrally with and projecting at an angle from the panel wall.

Abstract: A transmission control device which receives steering inputs and speed inputs, and produces an input for a steer transmission and an input for a drive transmission in order to control the direction and speed of a vehicle. The transmission control device, coupled to a steering assembly, coordinates the steering inputs with the speed inputs. The steering assembly which includes an elongated force transmitter operatively coupled to a steering device. The force transmitter, which is operatively coupled to a plurality of front wheels, has a fore-aft path of movement for pivoting the front wheels clockwise or counterclockwise. The present invention enhances the user's control and maneuverability of vehicles.
