Abstract
A multiple position stakedown assembly for a horizontal directional drill machine which installs stakes into the ground in a variety of different locations with a single drive head. The stakedown assembly includes a vertical tower that is rotatably mounted on a base plate. Locator ports for the stakes are provided in the base plate in a segmentally circular pattern around the tower. A drive head cantilevered from the top of the tower rotates with the tower to positions where it can install stakes through any of the ports.
