Air seeder frame force control

A seeding implement comprising:

• a support arm having a support arm first portion and a support arm second portion branched from the support arm first portion;
• a closing wheel support arm pivotally mounted to the support arm second portion at a first end of the closing wheel support arm, and a closing wheel connected to the closing wheel support arm at a second end of the closing wheel support arm;
• a closing wheel force actuator pivotally connected to the second support arm at a first end of the closing wheel implement force actuator and connected to the closing wheel support arm at a second end of the closing wheel force actuator, wherein the closing wheel force actuator is selected from the group consisting of a hydraulic cylinder, a pneumatic cylinder, and an electrically driven linkage;
• a firming implement support arm pivotally connected to the support arm second portion at a first pivot at a first end of the firming implement support arm;
• and
• a firming implement load sensor disposed on the firming implement support arm.
