In certain example embodiments of this invention, the lawn mower includes one or more of: (a) cutter deck baffle teeth for improving cutting performance; (b) a trim divider edge portion of the cutter deck for improving cutting performance; (c) a trim vacuum structure portion of the cutter deck for improving cutting performance; and/or (d) a center vacuum structure portion of the cutter deck for improving cutting performance.

A plant harvesting system is provided for use with a vertical hydroponic tower, the hydroponic tower containing a plurality of vertically aligned plants. The harvesting system includes a payload transport system and a harvester. The payload transport system, which is configured to be positioned at a location adjacent to the hydroponic tower, includes a base and a lift tower, the lift tower including a motorized lift system configured to move the harvester upward and downward. In addition to cutting plant stalks while moving upwards along the face of the hydroponic tower, the harvester also groups and collects the plant leafs.

A crop divider assembly of an agricultural header includes a first portion pivotally coupled to a frame of the header and a second portion having a first end and a second end. The second end is pivotally coupled to the first portion. The first end forms a leading end of the crop divider assembly. The crop divider assembly is moveable to a first configuration in which the first portion and second portion are at least partially aligned with one another and the first end is in a fully extended position, a second configuration in which the second portion is pivoted at an angle relative to the first portion such that the first end is moved rearwardly from the fully extended position to a retracted position, and a third configuration in which the second portion is pivoted relative to the first portion and the first end is positioned rearward from the fully extended position.
