Abstract
A post driver includes a sleeve for supporting a post as the post is driven into the ground and a driver for driving the post into the ground while the post is supported by the sleeve. The sleeve defines a channel that is dimensioned and arranged to receive the post so that the post can slide through the channel as the post is driven into the ground and the driver is dimensioned and arranged to slide over the sleeve. Preferably, the sleeve extends to the right height above ground and one embodiment includes a spade attached to a lower end of the sleeve for breaking the ground. A method of driving a post into the ground includes the steps of providing a sleeve for supporting the post as the post is driven into the ground and a driver for driving the post into the ground while the post is supported by the sleeve. The user places the post within the sleeve, the driver over the post and the sleeve, and the post and the sleeve in a generally vertical position at a location on the ground where the post is to be driven. The user then operates the driver to drive the post into the ground, preferably breaking the ground first using a spade on the end of the sleeve. Driving the post until the upper end of the post is even with the upper end of the sleeve automatically sets post height.
