Abstract
An agricultural disc opener is operable to be advanced in a forward direction along the ground to plant seed. The disc opener includes a suspension, a disc blade, a seed firming wheel, and a closing wheel. The suspension includes an elongated closer/firmer walking beam pivotally mounted relative to the suspension for pivoting about a lateral beam pivot axis. The wheels are rotatably mounted on the walking beam on opposite forward and aft sides of the beam pivot axis, with the walking beam configured to pivot as the wheels travel over the ground.
