A vehicle has a vehicle frame having a first end and a second end and a first siderail and a second siderail spaced laterally and each extend longitudinally from the first end to the second end. A caster wheel having a lateral axis is rotatably coupled to the vehicle frame towards the first end. Drive wheels defining an axis are rotatably coupled to the vehicle frame towards the second end. A prime mover coupled to the vehicle frame has a base and a vertical driveshaft, which is in operative communication with the drive wheels, extending from the base. The vertical driveshaft has a driveshaft axis closer to the second siderail than the first siderail laterally and closer to the caster wheel axis than the drive wheel axis longitudinally. The base is positioned vertically below most of the length of each of the first siderail and the second siderail.

Implements and applicators provide for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a base disposed between adjacent rows of plants, and at least one application member connected to the base and disposed to apply fluid to a rhizosphere of a row of the plants.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a base, at least one flexible or pivoting application member connected to the base and disposed to apply fluid to the plants, and a stabilizer associated with the at least one flexible or pivoting application member. The stabilizer can reduce movement of the application member to provide a more consistent fluid application to the plants.

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.
