Abstract: A boom for mounting to an agricultural sprayer comprises an elongate frame supporting a plurality of liquid application devices, liquid delivery means connected to the application devices, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent material from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.

Abstract: A boom for mounting to an agricultural sprayer which includes an elongate frame that supports a plurality of liquid application and delivery means, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent liquids from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.

Abstract: A boom mounting assembly for attachment to an agricultural application machine is provided. The assembly includes a boom support frame which is suspended from a primary frame mounted to a chassis. The boom support frame comprises a transverse beam for supporting an intermediate section of a fluid application boom. The suspension mechanism allows both yaw and pitch of boom support frame relative to the primary frame resulting from fore and aft forces on the boom. Dampers are each connected between the primary frame and the boom support frame at a position spaced from the transverse center of the assembly. Damping of pitch and asymmetrical yaw movement of the transverse beam away from a neutral position is controlled by the first and second dampers.

Abstract: A self-propelled agricultural application machine includes a chassis which carries a storage tank for the material to be applied. The chassis has a central longitudinal beam from which at least a pair of wheels is suspended. A transversely-extending boom assembly is suspended from the longitudinal beam. An engine is located to one side of the longitudinal beam and has an output drive shaft connected through the longitudinal beam to hydraulic pumps. The narrow chassis allows steerable wheels to be positioned at tolerable track widths while permitting a large steering angle and thus small turning radii.

Abstract: A self-propelled agricultural application machine (10) comprising a chassis (100) which carries a storage tank (15) for the material to be applied is provided. The chassis (100) comprises a central longitudinal beam (110) from which at least a pair of wheels (12, 14) are suspended. The narrow chassis (100) allows steerable wheels to be positioned at tolerable track widths while permitting a large steering angle and thus small turning radii.

Abstract: An agricultural sprayer comprises a pump system for conveying and distributing fluid between fluid sources and consumers. The pump system comprises a centrifugal pump and a multi-inlet ball valve located on a suction side of the pump. The centrifugal pump comprises an impeller that rotates on a pump axis. The ball valve comprises a ball that is rotatable around the pump axis to selectively connect the valve inlets to the pump. The pump comprises a pump casing that is provided together with a portion of a ball valve casing by a unitary casting.

Abstract: A boom mounting assembly (20; 120; 220) for attachment to an agricultural application machine (10) is provided. The assembly comprises a boom support frame (22) which is suspended from a primary frame (24) mounted to a chassis. The boom support frame comprises a transverse beam (35) for supporting an intermediate section of a fluid application boom (16). The suspension mechanism allows both yaw and pitch of boom support frame relative to the primary frame resulting from fore and aft forces on the boom. Dampers (50, 52) are each connected between the primary frame and the boom support frame at a position spaced from the transverse centre of the assembly. Damping of pitch and asymmetrical yaw movement of the transverse beam away from a neutral position is controlled by the first and second dampers.

Abstract: An agricultural application machine (10) comprising a pair of wheels (11, 12) each having an associated wheel support structure (22) is provided. Each wheel support structure is mounted to the chassis (60) by a transversely extending support shaft (29; 49) which is slidably mounted within a bearing block (50; 80). The provision of bearing blocks allows the transverse separation of the wheels to be varied with minimal sliding friction.
