Abstract: An agricultural machine such as a high clearance sprayer is provided with a frame capable of supporting wheels at a variable tread width. The frame includes a pair of cross members, both of which have slider receivers. The machine also includes a first axle slider for a first side and a second axle slider for a second side. The machine may also have a slider to frame connection arrangement that includes a reduced friction zone at the slider receivers that facilitate telescopic movement of the axle sliders. The slider to frame connection may also have at least one fixed slider wear pad in a fixed position within the reduced friction zone and at least one movable slider wear pad movably arranged within the reduced friction zone.

Abstract: A self-propelled agricultural sprayer can be configured with a spray boom, adjustable width wheels and rear wheel spray nozzles arranged over rear wheels of the adjustable width wheels, so that the rear wheel nozzles ensure proper coverage of an agricultural field behind the rear wheels according to location. A control system can determine front wheel nozzles disposed on the spray boom that are counterpart spray nozzles to the rear wheel nozzles based on a width of the wheels, and implement activation/deactivation states of the rear wheel nozzles based on the counterpart front spray nozzles. The activation/deactivation states of the spray nozzles can be determined by geographic location of the machine using a UPS location. The rear wheel nozzles can be arranged with respect to fenders of the rear wheels, so that the rear wheel nozzles move laterally with the rear wheels.

Abstract: 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.

Abstract: An engine hood mounting system includes an engine hood having at least one engine hood pivot support disposed on an inner surface thereof, at least one pivot joint located on a chassis frame of the agricultural machine, and at least one pivot bar assembly configured to interfit with a respective pivot joint and engine hood pivot support. The at least one pivot bar assembly includes an outer pivot bar having a first end and a second end and an inner pivot bar disposed within the outer pivot bar having a first end and a second end. The outer pivot bar and the inner pivot bar are coupled to each other via at least one fastener. Further, the at least one pivot bar assembly, its respective engine hood pivot support, and its respective pivot joint are oriented along a rotation axis.

Abstract: A rinse tank for use with an agricultural machine that has a routing tunnel formed in a tank bottom wall for routing hoses through the routing tunnel between the rinse tank and a frame side-rail associated with the agricultural machine. The routing tunnel allows hoses to be routed from a first end of the agricultural machine to a second end of the agricultural machine. Additionally, brackets can be installed to the top wall of the frame side-rail. The brackets can be used to help locate the rinse tank about the frame as they are configured to fit within the routing tunnel. Additionally, the hoses can be routed through the brackets to prevent the hoses from being misplaced or damaged once the rinse tank is installed onto the frame side-rail.

Abstract: An engine compartment side panel is configured for toolless mounting and includes a main body having an outer surface, an inner surface, and a bottom edge. The side panel further includes at least one tab disposed at a location along a length of the bottom edge of the main body. In addition, a handrail is coupled to an outer surface of the main body at a plurality of handrail mounting locations and at least one mounting arm is coupled to an inner surface of the main body at a respective one of an at least one mounting arm mounting locations. Each mounting arm is configured to be removably coupled to an engine compartment support frame. Further, each of the at least one mounting arm mounting location is aligned with a respective one of the plurality of handrail mounting locations.

Abstract: One or more vehicle sensors can be used in a suspension control system of an agricultural machine to dynamically adjust pistons located proximal to wheels of the machine to substantially control orientation. Such vehicle sensors could include: a speed sensor configured to provide an output indicating a speed of the machine; a turn angle sensor configured to provide an output indicating a turn angle of the machine; and/or an Inertial Measurement Unit (IMU) configured to detect a chassis-to-horizon angle. The output can be compared to a threshold for determining when to control valves in the suspension system to apply height corrections.

Abstract: Electronically controlled hydraulic valves can be directly mounted to rear steering cylinders of a four wheel steering machine to improve steering, reduce space consumption, reduce leak points and allow ease of routing. The valves can receive hydraulic fluid from a pump and release hydraulic fluid to tank, while controlling an amount of hydraulic fluid to the steering cylinder via inlets and outlets in direct contact. The valves can be controlled by a controller that is also in communication with position sensors configured to sense positions of the front and rear steering cylinders, so that the directly mounted valves in the rear can be correspondingly controlled to follow steering in the front.

Abstract: A lock system can be provided at each rear wheel assembly of a four wheel steering system to physically lock the rear wheel assemblies in a fixed direction to safely prevent rear wheel steering when such feature is undesirable. The lock system can use an electronically controlled actuator to hydraulically drive or retract a lock cylinder to lock or unlock the rear wheel assemblies, respectively. Sensors can be used to detect whether the lock cylinders are driven or retracted by their respective actuators, so that a controller monitoring the sensors can determine whether four wheel steering is enabled or disabled.
