30 Hex Auger Drive Dig holes with speed and plumb-line accuracy using a Bobcat auger attachment. Using heavy-duty hydraulics, the auger attachment bites into any soil condition with ease and efficiency. Even in hard and rocky soil, the high torque keeps the auger steady and powerful to maintain performance. Choose between a direct drive auger for an optimum balance between torque and RPM, or a gear-driven planetary auger for applications that require the most torque. Multiple bit types and teeth enable you to find the right auger to match your digging conditions. The direct drive 15 offers a higher range of speed for drilling holes quicker through softer to moderate soil conditions such as sand, dry material, and light dirt so the hole being dug is cleaned out better. The direct drive 30 and the planetary drive augers offer higher amount of torque for digging into heavier ground surfaces such as rocky, coral or clay. With lower speeds to dig, Planetary augers provide the torque needed to install screw anchors and dig with bits that are over 24 inches in diameter.
