Abstract
A grapple mechanism is connected to a post driver on one side, rather than in the front of the post driver. The grapple connects to the post driver via a hinge which allows substantially 90 degrees of rotation between a horizontal position for picking up posts, and a vertical position for driving the post into the ground. A spring or other biasing mechanism preferably biases the grapple mechanism toward its horizontal position. However, the spring is preferably not so strong as to hold the grapple mechanism in the horizontal position even when a post is grappled. Preferably, the weight of a grappled post is sufficient to overcome the spring, causing the grapple mechanism to pivot about the hinge and into the vertical position. The grapple mechanism is therefore preferably sized, shaped and weighted so as to swing to a substantially vertical position when a post is grappled and lifted.
