Modular meter units for distributing particulate material from an applicator can be configured to combine with each other without the use of tools to provide specific meter assembly lengths based on desired flow rates. In one aspect, modular meter unit housings with interlocking features can provide build options for assembling different sized meter assemblies. The modular meter unit housings can allow stacking and connecting multiple adjacent meter units to make a meter assembly of a particular length/volume/flow rate. Each meter unit housing can have a longitudinal bore that opens through opposing end walls and define a cylindrical cavity or chamber that can receive a cylindrical/tubular sleeve or liner. Matching openings on opposite top/bottom walls of the modular meter unit housing can align with openings of the liner to define an inlet and outlet for the meter unit.

A row unit for a seed-planting implement includes a frame and a disk opener supported relative to the frame and configured to form a furrow within a field. The row unit further includes a gauge wheel arm supported relative to the frame, and a gauge wheel coupled to the gauge wheel arm. Additionally, the row unit includes a sensor assembly having a rotational sensor, a first sensor arm, and a second sensor arm. A proximal end of the first sensor arm is coupled to the rotational sensor, a proximal end of the second sensor arm is coupled to a distal end of the first sensor arm, and a distal end of the second sensor arm is coupled to the gauge wheel arm. The rotational sensor is configured to generate data indicative of a position of the gauge wheel arm based on movement of the first sensor arm.
