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.
Sometimes you need to dig deeper to prepare a footing or sump drain, reach stable subsoil or dig below the frost line. Bobcat augers provide design and geometry that helps do the job right. See how other brands compare. With auger attachments, torque equals power. Greater torque makes it easier to break down rock, power through tree roots or clay, and take on frozen ground.
All augers have published torque ratings, but performance on the jobsite matters most. The torque challenge video evaluates the difference. Direct drive models use a directly mounted hydraulic motor, while planetary models are powered by a gear drive system. The motor turns the output shaft, which is connected to an auger bit to drill into the ground.Direct drive augers are ideal for digging holes for posts, piers, poles, or trees. Planetary augers deliver the power and force needed to dig in anchor applications and through other extreme ground conditions including rock, shale, clay and frost.
