A stakedown assembly for a horizontal directional drill that multiplies the travel of a hydraulic cylinder so that the drive head travels twice the distance of the hydraulic cylinder travel. A gear pinion is pivotally attached to a top end of the hydraulic cylinder. A first gear rack is fixedly attached to a tower, and a second gear rack is fixedly attached to a drive head. The gear pinion floats between the two gear racks, thus, producing multiplication when the hydraulic cylinder is actuated. This allows the use of a shorter hydraulic cylinder and results in a smaller overall stakedown assembly height.

Stakedown assembly for a horizontal directional drill

A coupling for quickly and easily attaching and detaching stakes from the drive head of a horizontal directional drill. The coupling includes an upper coupler member and a lower coupler member. The lower coupler member slides into the upper coupler member, and a pin in the upper coupler member rotates into opposed, horizontal slots in the lower coupler member.

Stake coupler for a horizontal directional drill

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.
