Abstract
Described herein are air seeders that have force actuators acting on at least one of the firming implement and closing wheel to adjust for a specified downforce on at least one of the firming implement and the closing wheel. In one example, a seeding implement includes a support arm having a support arm first portion and a support arm second portion. A firming implement support arm is pivotally connected to the support arm second portion at a first pivot at a first end of the firming implement support arm. A firming implement force actuator is pivotally connected to the support arm second portion at a first end of the firming implement force actuator and connected to the firming implement support arm at the second end of the firming implement force actuator.
