Towable Hydraulic Auger

Used Towable Hydraulic Auger Ground Hog (Auger Bit Not Included)

The Ground Hog HD99 is a Towable Hydraulic Earthdrill designed to be robust, easy to use, and require minimal maintenance.

The HD99 is the most potent earthdrill in the Ground Hog line.

With its 9hp Honda or Subaru engine, the HD99 can easily dig with any Ground Hog auger up to 18 inches in diameter.


The use of hydraulics allows the HD99 to have variable auger speed and reverse, which is very useful if the drill gets stuck.

The HD99 design is almost perfectly balanced with an 8-inch auger attached, so it takes the load off of the operator.

Three handlebar positions allow regular drilling and close-up drilling next to an obstacle, such as a wall or fence.

The drilling head also pivots from side to side for drilling on uneven terrain.

Large highway-rated tires make the HD99 easy to maneuver around the job site, and a locking mechanism on the digging head holds the drill up and out of the way for moving the machine around the job without disconnecting the auger.

The heavy-duty powder-coated steel construction of the HD99 uses a pivoting engine cradle that protects the engine and lets it stay level for proper oiling and longer life.

The frame’s low profile and compact design eliminate the need for telescoping booms and axles and allows its transportation in the bed of a small truck.

The HD99 also has a towbar with a 2″ hitch coupler and safety chains for surface street and job site transport.

The hydraulic system used on the HD99 is highly reliable and requires very little maintenance compared to mechanical systems, and the HD99 uses high-quality Parker components.

All the care usually needed is to check or change the hydraulic fluid and engine oil and replace the hydraulic filter.

The uniquely shaped fluid reservoir holds 3 gallons of sap with a large surface area to dissipate heat for higher efficiency.

The pool has a dipstick for checking the liquid level, the drain plugs for the hydraulic fluid and engine oil, and the hydraulic filter are easy to access and use without making a mess.
