Auger Boring Machine


Auger Boring Machines



Spoil door for safety

Quick Tran and Rack and Pinion allows for fast return

Quick split frame allows the machine to be separated for lighter and faster lifts


The 72-1200 Auger Boring machine has an increased ability to pull auger, steering rods, and push product. Better visibility to the master pusher with a low centerline and wide stance provides improved stability. Hydraulically-assisted clutch is easier and more comfortable to operate. The machine locks safely to the track without hook rollers. Ergonomic operating button allows for feathering rotation and slow turn of the shaft for easy auger installation. Safer operation with emergency shutdown switch at the operator’s station as well as an operator presence tethered switch. Updated gauge system includes the improved engine tachometer, engine warning light, & hydraulic thrust pressure reading and vivid graphics guide safe and proper machine operation.

(4,536 kg) of push/pull at high speed, and there will be no dogging or winching during retract, as the Quik Tran system engages directly to the machine track. Quik Trans benefit will be easier machine operation in challenging work climates or conditions.

Spoil Door

  • With a Safety-First commitment, all American Augers horizontal earth boring machines are equipped with a gravity activated-manual spoil door, which deflects thrown debris from the spoil chamber.
