A method of detecting leakage within a chassis includes mounting the chassis on a plate disposed in a sealed chamber and fluidly connecting, by a pipe, an interior space of the sealed chamber to a water tank such that a bottom end of the pipe is under a surface of water in the water tank. The method further includes determining, such as observing, whether bubbles are formed at the bottom end of the pipe due to pressurized air flowing into the pipe. The method also includes determining presence of a leak in the chassis due to pressurized air flowing between the chassis and the sealed chamber, before flowing into the pipe.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

Disclosed is a method and laboratory instrument aimed at reducing the loss of time of liquid level determination each time a liquid container is loaded into an instrument and at the same time reducing waste of liquid containers due to unforeseen changes in the liquid levels by combining a fast liquid level check at an expected liquid level with a liquid level search if no liquid level is found at the expected level, while also ensuring proper liquid aspiration as the liquid level is always verified (expected level is not blindly relied upon).

A system for controlling a ground speed of an agricultural sprayer includes a speed setting device for commanding a selected ground speed of the sprayer when operating within a speed-range mode associated with a ground speed range. The speed setting device is movable across a plurality of positions, with each position being associated with a different ground speed within the ground speed range. A maximum range speed of the ground speed range is lower than a maximum ground speed of the sprayer. As such, the system includes a speed override input device for commanding that the ground speed of the sprayer be increased to the maximum ground speed. When an override input is received from the speed override input device, the computing system controls the operation of a sprayer drive system to increase the ground speed of the sprayer from the selected ground speed to the maximum ground speed.

An agricultural sprayer includes a purge tank, a nozzle configured to dispense an agricultural fluid onto an underlying field, and a downstream valve configured to selectively permit the air from the main fluid conduit to flow to the nozzle. A computing system is configured to initiate a purging operation to purge the agricultural fluid present within the nozzle and, upon receipt of the input, control an operation of a main valve such that the main valve is moved to an opened position to allow the air to flow through a main fluid conduit. In addition, the computing system is configured to monitor a first air pressure associated with the purge tank and a second air pressure associated with the nozzle. Furthermore, the computing system is configured to control an operation of the downstream valve during the purging operation based on the monitored first and second air pressures.

An agricultural sprayer includes an actuator configured to adjust the position of a boom assembly of the sprayer relative to a frame of the sprayer. A computing system is configured to determine the operating parameter of the sprayer at a current time based on received sensor data. Moreover, the computing system is configured to anticipate when the boom assembly will move relative to the frame in a fore/aft direction at a future time based on the determined operating parameter, with the fore/aft direction being parallel to a direction of travel of the agricultural sprayer. In addition, when it is anticipated that the boom assembly will move, the computing system is configured to control the operation of the actuator before the future time such that movement of the boom assembly relative to the frame is reduced at the future time.

A system for an agricultural sprayer is provided herein that includes a tank fluidly coupled with a flow assembly. A nozzle assembly is positioned along a boom assembly and is fluidly coupled with the flow assembly. A purge system is configured to remove agricultural product from the flow assembly. A computing system is communicatively coupled to the purge system. The computing system is configured to receive an input to initiate the boom purge system; activate a valve of the purge system; determine whether one or more predefined conditions are detected; and exhaust the agricultural product from the flow assembly through the purge valve when each of the one or more predefined conditions are detected.

An agricultural sprayer includes a purge tank and first and second nozzles. Furthermore, the system includes a first valve fluidly configured to selectively permit air to flow to the first nozzle and a second valve fluidly configured to selectively permit the air to flow to the second nozzle. A computing system is configured to receive an input indicative of initiation of a purging operation and, upon receipt of the input, control an operation of a main valve to allow the air to flow through a main fluid conduit. Furthermore, the computing system is configured to monitor the air pressure associated with the purge tank and control the operation of the first and second valves during the purging operation based on the monitored air pressure.
