Header assembly for an agricultural harvester

A header assembly for an agricultural harvester, comprising:

• a lift arm pivotally coupled to a chassis of the agricultural harvester;
• a toolbar pivotally coupled to the lift arm, wherein the toolbar supports a row unit;
• a lift actuator pivotally coupled to the lift arm and pivotally coupled to the chassis of the agricultural harvester, wherein the lift actuator drives the lift arm to rotate relative to the chassis of the agricultural harvester to control a vertical position of the row unit relative to the chassis of the agricultural harvester;
• a tilt actuator pivotally coupled to the lift arm and to the toolbar, wherein the tilt actuator drives the toolbar to rotate relative to the lift arm to control an orientation of the row unit relative to the chassis of the agricultural harvester;
• and
• a controller communicatively coupled to the lift actuator and to the tilt actuator, wherein the controller comprises a processor and a memory, the controller controls the lift actuator to control the vertical position of the row unit relative to the chassis of the agricultural harvester, and the controller controls the tilt actuator to control the orientation of the row unit relative to the chassis of the agricultural harvester.
