Abstract: A drop nozzle system on an agricultural vehicle such as a sprayer unit includes a plurality of mounting plates attached in a spaced manner to a trailing boom structure. A plurality of drop nozzle assemblies each coupled by suitable hosing to the nozzle bodies on an agricultural spray boom are adapted for secure attachment to the mounting plates. With the mounting plates attached to the boom structure at predetermined, standard row spacings such as 30", 34", 36", 38", etc., the drop nozzle assemblies may be attached to the appropriately spaced mounting plates as determined by the inter-row spacing of the field to be sprayed. Attachment of each nozzle assembly to a respective mounting plate employs a quick disconnect coupling arrangement which facilitates re-configuring the drop nozzle system for various inter-row spacings.

Abstract: A cushion suspension system for coupling an agricultural tool to a vehicle includes a flexible frame which permits vertical movement of the tool relative to the vehicle while maintaining the tool laterally fixed relative to the vehicle to prevent side-by-side oscillation. The flexible frame includes an air spring with an air filled bellows for providing vertical cushioning and a restoring force as the wheels of the vehicle encounter irregularities in the ground. Pressure within the air spring is adjustable to accommodate a range of agricultural tool sizes. The frame further includes a shock absorber for dampening vertical oscillation of the frame, with stops provided for limiting upward and downward displacement of the tool. The suspension system is particularly adapted for attaching an agricultural boom having a plurality of nozzles to a trailer-type sprayer.

Abstract: A boom, particularly a spreading boom for suspension on an outer frame (1) of an agricultural tool and of the type in which the suspension device comprises spring suspension and shock absorbing devices in the form of a trapezoidal suspension with two substantially parallel beams of which one is connected to the outer frame (1). According to the invention the upper beam of the trapezoidal suspension is linked, each of the links (6, 7) being pivotally connected to the outer frame (1) and springs (12) being arranged on both sides of the linkage (20, 21), but on the other side of the center of suspension (8, 9). The individual spring (12) is arranged between one of said links (6, 7) and a separate beam fastened to the outer frame (1).
