According to one embodiment, there is provided a breakaway hinge for an expandable boom on an agricultural vehicle. The boom includes of a first and a second section combined in a manner to allow the second section to move with respect to the first section when the second section encounters an obstruction. A breakaway hinge is provided between the first and the second section, and includes a first pivot member attached to the first section at an angle with respect to a vertical line and a second pivot member attached to the second section at an angle with respect to the vertical line. A connecting member holds the first pivot member with respect to the second pivot member.

An apparatus for cleaning a surface, such as the surface of a rotating disk, the apparatus comprising an articulating arm associated via a linkage to a rotating member driven by a motor. Rotation of the rotating member causes linkage to move the articulating arm in an oscillating pattern. A nozzle associated with the distal end of the articulating arm can convey pressurized air or liquid from a source to a surface in an oscillating pattern based on the construction of the arm, linkage, the rotating member and the speed of rotation.

A product applicator system for distributing a liquid product accurately using low volume applications which minimize the quantity of product used and ensures more accurate results. The product applicator system generally includes a housing which includes a removable inlet port mount and outlet port mount. The positioning of the inlet and outlet port mounts on the housing is interchangeable. Supply hoses provide a product to the inlet port mount where the product is traversed through internal conduits to exit the housing via oscillating and overlapping spray heads. An internal motor provides oscillating motion to the spray heads. A rotator assembly which includes a rotator motor may be utilized to orient the housing in horizontal, vertical, or various diagonal orientations. The housing is adapted to either connect to a vehicle, be positioned on a stationary or movable platform, or be connected to a boom using boom connectors.

The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.
