"Wobble Auger" Offers Dirtless Digging
"Our new Wobble Auger produces a hole that has no loose dirt in the bottom or around the top of the hole. It pushes right through dirt, sand, clay, asphalt, and even rocks," says Glen Danuser, Danuser, Fulton, Mo.

    The Wobble Auger is designed to operate off hydraulic auger systems using skid loaders, backhoes, or excavators. It measures 4 ft. long and is available in 4, 6, and 9-in. diameters. The unit consists of a tapered steel cone with spiral-checkered hardfacing, with various collar options available. The center column and point are true, but the cone itself is offset, which makes it wobble as it pushes into the ground.

    "The point at the bottom of the auger goes into the ground straight, but then the tapered cone slowly starts to push dirt toward the outside edges of the wall and compacts the walls tight," says Danuser. "A high torque auger system with a tremendous amount of down force produces the best results.

    "You're not digging anything, you're pushing material into the sidewalls. It works somewhat like pounding a stake in the ground and then removing it to see a clean hole."

    A flightless auger won't retract dirt from holes, and therefore pays for itself in labor savings, says Danuser. "We asked people in the fencing industry what was their biggest problem, and they said having to remove loose dirt at the top and bottom of the hole and shovel it out of the way.

    "We don't know how useful the Wobble Auger will be for farmers, because it leaves very little dirt to tamp. However, you could use the Wobble Auger to make pilot holes. For example, you could make a 4-in. dia. hole and then use it to drive in a 6-in. dia. post."

    One advantage to a flightless auger is that it can't grab rocks or tree roots and get stuck, says Danuser. "With a conventional hydraulic-operated auger, as soon as the motor reaches its top torque level the motor bypasses and shuts down. Then you have to reverse the auger and try again. But when the Wobble Auger encounters a rock, it just pushes the rock to the side."

    The Wobble Auger requires down pressure to work. "It works kind of like a putting in screws with a cordless drill," says Danuser. "For example, if you try to use a cordless drill to put a 4-in. screw into treated wood, at first it goes in fine. However, as the screw goes deeper into the wood, the drill starts to growl because it needs more torque. The same principle applies with the Wobble Auger. As the auger goes deeper into the ground, the skid loader has to push down on it to fight through the resistance."

    He says the Wobble Auger isn't designed to be pto-operated off a 3-pt. hitch. "A 3-pt. hitch can't deliver adequate down force. Also, pto-operated augers are designed to have shear bolts in case they meet resistance."

    The 4-in. dia. auger sells for $285 plus S&H; the 6-in. for $360 plus S&H; the 9-in. for $550 plus S&H. Various collar options are available.
