Agricultural machines having sectional control, and related systems and methods

A sectional control system for controlling a flowrate of particulate material to different sections of an agricultural machine, the sectional control system comprising:

• a product bin configured to store particulate material;
• a conveyor including a conveyor belt configured to convey the particulate material to the sectional control funnel box from the product bin;
• a distribution plate including a plurality of apertures;
• a sectional control funnel box mounted on the distribution plate, the sectional control funnel box configured to receive the particulate material from the conveyor, the sectional control funnel box comprising a plurality of chutes extending therethrough and connecting the sectional control funnel box to the distribution plate;
• a plurality of distribution lines, each distribution line configured to receive the particulate material from a single aperture of the distribution plate and provide the particulate material to a distribution point of the distribution line;
• a geo-positioning receiver configured to receive geo-positioning information;
• and
• control circuitry configured to:
• determine locations where the particulate material has previously been applied based, at least in part, on the geo-positioning information;
• and
• control a flowrate of the particulate material to different subsets of chutes based on a location of the agricultural machine relative to the locations where the particulate material has previously been applied.
