Abstract:
1. A method for controlling a seeding apparatus comprising: sensing a ground force acting on a furrow opener of the seeding apparatus, the ground force being dependent upon the soil condition of the ground, and providing a ground force sensor signal in dependence upon the ground force acting on the furrow opener; providing an actuator to apply a bias force to a packer wheel of the seeding apparatus; and providing a control device operative to receive the ground force sensor signal and an input from an operator and to change 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 such that a packing force exerted by the packer wheel onto the ground is changeable in dependence upon a change in the soil condition of the ground.
