Abstract
An agricultural seeding implement has a seed hopper that is weighed continuously during field operations as the seed volume in the hopper progressively diminishes. The weight information is used to perform ongoing control functions on the implement. One embodiment uses the weight information to reduce the down pressure on compaction wheels of a wing section of the machine as a function of the diminishing weight of the hopper on the main section.
