Abstract
A method for controlling a seeding apparatus including sensing a ground force acting on a furrow opener of the seeding apparatus and providing a ground force sensor signal in dependence upon the ground force acting on the furrow opener. The method further includes providing an actuator to apply a bias force to a packer wheel of the seeding apparatus. The method also includes providing a control device operative to receive the ground force sensor signal and an input from an operator and to adjust the bias force that the actuator applies to the packer wheel in dependence on at least one of the ground force sensor signal and the input from the operator.
