Planter row unit adjustment control

A row unit for a seeding machine operable to plant seeds into soil, the row unit comprising:

• a frame supporting a furrow opener for opening a furrow in the soil, a gauge wheel for rolling atop the soil, a seed dispenser for dispensing seeds into the furrow, and a furrow closer for closing the furrow;
• a furrow closer downforce actuator operable between the row unit frame and the furrow closer to exert an adjustable force that pushes the furrow closer downward on the soil;
• and
• a controller programmed to increase downforce in response to a detected increase in travel speed of the row unit.
