Abstract: The post driver with limited movement floating post anvil does not rely heavily upon the skill of the operator to efficiently drive posts. The post anvil is allowed to move up and down in relation to the driver, but its movement is limited by both lower and upper fixed barriers. Since the movement is limited, the operator can position the driver upon the post allowing the full weight of the driver framework/carrier machine to rest upon the post. The post would push the floating post anvil upward only to the point at which the upper fixed barrier prevents further upward movement of the floating post anvil. Thus, once the floating post anvil abuts the upper fixed barrier, substantially the entire weight of the post driver is resting on the post.
