Abstract: An autonomous tractor for autonomously crossing farmland, includes one or more sensors for detection of an obstacle when crossing the farmland, and a central processing unit (CPU) for receiving input signals from the the sensors and for controlling movement of the tractor based on the input signals in order to avoid the obstacle, a coupler for coupling an agricultural machine able to be coupled to the tractor, and the agricultural machine includes one or more additional sensors for detection of the obstacle, wherein coupling of the agricultural machine operatively connects the additional sensors to the CPU and automatically provides data to the CPU regarding the location of each of the additional sensors on the agricultural machine and one or more specifications of each of these additional sensors.

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: An agricultural sprayer includes an ozone supply arranged to clean at least a portion of the sprayer after a spraying operation has been completed, by supplying ozone to the residual spray liquid and to the interior of the sprayer plumbing. The ozone supply may be preceded by a rinsing or flushing of the sprayer plumbing using a rinse fluid, with the ozone injected to a circulating fluid in the sprayer plumbing. The sprayer may have an auxiliary liquid tank, such that residual spray liquid may be drained to the auxiliary tank to be cleaned using ozone. Such a cleaning operation can be performed at the same time as a further spraying operation, thereby providing for improved efficiency of operation of the sprayer.

Abstract: A boom suspension assembly for an agricultural sprayer having a chassis, a lift arm assembly mounted to the chassis, and a boom support frame pendulously suspended from the lift arm assembly. Springs and dampers between the chassis and the boom support frame control pitch and yaw movement of the boom support frame away from a neutral position. The lift arm assembly, boom support frame and dampers provide a four-bar linkage which maintains the boom support frame in a steady alignment when raised and lowered.

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: An agricultural trailed implement includes a chassis with tongue for hitching to a tractor. A housing is integrated into a loadbearing section of the tongue. A pump or generator is mounted inside the housing and is driven by a PTO shaft connected to an attached tractor. The pump housing may define a sump which provides a fluid reservoir to supply the pump in a hydraulic circuit.

Abstract: An agricultural sprayer including an applicator boom which itself includes a centre boom frame and a pair of multi-section boom side assemblies. Each side assembly is mounted by a respective hinge to the centre boom frame. Neighbouring boom sections are mutually connected by a hinged joint which permits folding around an upright axis from a deployed operating configuration to a transport configuration. A spring and damper mechanism is associated with the hinged joint for controlling pivoting movement around the upright axis between said two boom sections.

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: An agricultural sprayer boom comprises vertically spaced upper and lower beams extending along the boom and connected by brace members formed from a unitary bent tubular member that is secured to the upper and lower beams, and gripped, by clamps.

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.
