A roof coating sprayer including a cart assembly and a sprayer assembly. The cart assembly has a frame with a plurality of wheels. The frame has a sprayer support assembly with a lateral member, and vertical spray nozzle attachment members arranged along the lateral member. The attachment members each mount a spray nozzle and can be vertically and horizontally shifted relative to the lateral member. The roof coating sprayer can be pulled over the surface of a roof at a uniform rate, enabling a coating of a uniform thickness to be sprayed on the roof. Additionally, the cart assembly can be self-propelled, enabling a uniform rate of speed for the cart and thereby enabling uniform application of coating.

Sprayer apparatus for use with an elongate boom may be configured to spray a liquid onto foliage on a ground surface. The sprayer apparatus may include a spray boom, a spray hood coupled to the spray boom, an extension member coupled to the spray boom, and a mounting apparatus coupled to the extension member. The mounting apparatus may be couplable to the elongate boom to support the spray boom and the spray hood above the ground surface.

A system includes a first nozzle assembly positioned along a boom assembly. The first nozzle assembly includes a first valve operably coupled with a first nozzle. A first imaging device is associated with the first nozzle assembly. A second nozzle assembly is positioned along the boom assembly and includes a second valve operably coupled with a second nozzle. A second imaging device is associated with the second nozzle assembly. A computing system is operably coupled with the first nozzle assembly, the first imaging device, the second nozzle assembly, and the second imaging device. The computing system is configured to receive data from the first imaging device, identify a first reference point within the data provided by the first imaging device, receive data from the second imaging device, identify a second reference point within the data provided by the second imaging device, and determine a boom deflection model.

A manifold arrangement for a car wash liquid spray apparatus. The manifold arrangement has a water intake manifold and a plurality of nozzle manifolds in fluid communication with and extending from the water intake manifold having a plurality of liquid-expelling nozzles at varying distances away from the water intake manifold. A car wash liquid spray apparatus further has a bracket for mounting the apparatus to a car wash, the bracket having a pair of opposed supports, and the water intake manifold is rotatably coupled to the pair of opposed supports.

A boom for an agricultural machine includes a first, second and third boom sections. The first boom section is connectable to a vehicle, and can support fluid delivery components. The second boom section operably connected to and is foldable with respect to the first boom section about a fold axis. The second boom section is further coupled to move with respect to the first boom other than about the fold axis from an extended position in response to an external force, and to return to the first extended position upon removal of the external force. The third boom section is operably connected to the second boom and having at least in an extended position. The third boom section is operably connected to move with respect to the second boom in response to a second external force, and operably connected to return to the extended position upon removal of the second external force.

A work machine can include a frame; a spray system couple to the frame and including a spray bar having a plurality of nozzles; a pressure sensor to detect a pressure of a liquid within the spray bar; and a controller to determine whether the detected pressure of the liquid within the spray bar has exceeded a pre-determined pressure threshold.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.
