An agricultural treatment system can include one or more motor assemblies, linkage assemblies coupled to the motor assemblies, and a treatment head assembly coupled to the linkage assemblies. Each motor assembly can rotate about a motor assembly rotational axis and each linkage assembly can move in a direction in response to motor assembly rotation about a motor assembly rotational axis. Portions of the treatment head assembly can rotate about one or more treatment head assembly rotational axes in response to linkage assembly movement. The treatment head assembly can include a treatment head, a fluid port that delivers a fluid into the treatment head, spraying tip(s) that spray the fluid onto an agricultural target object, and a fluid regulator that delivers the fluid from the fluid port to the spraying tip(s). The fluid regulator can be coupled to and can rotate with the treatment head, which can be movable.

Implements include application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

The invention relates to a spray unit (10) with an axle (20), an atomising disc (30), a spray direction modifying assembly (40), and a liquid applicator (50). The atomising disc is configured to spin about the axle centred on the centre of the disc. The liquid applicator is configured to apply liquid to a surface of the atomising disc. The spray direction modifying assembly is in proximity to the atomising disc. The spray direction modifying assembly comprises at least one air channel (41). The at least one air channel is configured to provide air in proximity to the atomising disc to modify the subsequent trajectory of the liquid droplets that leave the outer edge of the atomising disc.

An agricultural sprayer comprising a first chemical supply tank; a pump configured to pump a broadcast chemical from the first liquid solution tank to plumbing on a boom for broadcast spraying; a second chemical supply tank; an injection pump configured to pump a selective spray chemical from the second liquid solution tank to plumbing on a boom for selective spraying; and a mixing chamber for mixing the broadcast chemical and the selective spray chemical prior to spraying.
