An equipment skid is aligned on the frame of an agricultural product applicator defining substantially mutually perpendicular fore-aft, transverse and vertical axes of the frame, by utilizing an alignment system having a vertically extending frame mounting surface defined by the frame, and a vertically extending skid mounting surface defined by the skid. The frame and skid mounting surfaces are adapted for mating connection with one another to substantially align the skid with the frame along a substantially vertical mounting plane. A pair of laterally-spaced, juxtaposed, vertically extending skid alignment features are defined by the frame mounting surface, and a skid-mounted alignment block extending from the skid mounting surface is adapted for insertion between and into operative engagement with the pair of skid alignment features for aligning the skid with the frame on the vertical mounting plane.

An engine compartment support arrangement for an agricultural machine includes first and second support rails disposed within an engine compartment, a horizontal platform disposed between the first and second support rails and coupled thereto, and a plurality of engine accessory mounts welded to at least one of the first support rail and the second support rail. The first support rail includes a horizontal portion and an angled portion, wherein a second end of the horizontal portion is aligned with a first end of the angled portion. The second support rail includes a horizontal portion and an angled portion, wherein a second end of the horizontal portion is aligned with a first end of the angled portion.

An articulated boom assembly comprises a base and a primary boom arm extending from the base. There is a power system for actuating the primary boom arm between an extended position and a retracted position. There is an attachment operatively connected to the primary boom arm which supports a nozzle. The attachment may include an actuating mechanism for reciprocating the nozzle along the length of the attachment.

A mobile washing system and methods for washing photovoltaic panels. The mobile washing system includes a vehicle, a fluid tank coupled to the vehicle, and a washing apparatus mounted to a side of the vehicle. The washing apparatus includes two generally longitudinal spray pipes that are configured to be rotated and vertically adjusted with respect to the vehicle to position the spray pipes generally parallel to a top surface of the photovoltaic panels.

A mixer truck water spray bar for suppression of dust clouds is disclosed. The mixer truck water spray bar generally includes an entrance chute configured to receive water from the drum via the mixer chute that is removably attachable to the mixer chute and a manifold attached to the entrance chute that is oriented substantially perpendicular to the entrance chute and is configured to receive water from the entrance chute via an entrance opening and comprises a plurality of apertures configured to externally distribute water received through the entrance opening through the apertures without the use of a pump.

A pressure washer apparatus for cleaning a paved surface includes a motor driven zero-radius turn vehicle with a rotary sprayer positioned below a body of the vehicle. A pump and a reservoir containing a fluid are coupled to the body. The pump is activatable to urge the fluid from the reservoir through the sprayer such that the fluid propels the sprayer to rotate and that the fluid is forced toward the paved surface to clean the paved surface.
