What type of auger attachment is suitable for a mini excavator?

One matched to your auxiliary hydraulic flow and your mount interface. The Loflin Fabrication Mini Auger runs on 6-40 GPM and uses a 2" hex output shaft that accepts bits from 4" to 48" in diameter. Its listed mounts are Toro Dingo and Bobcat MT50, 52, 55, S70 and RC30, so a machine with a different coupler needs a matching adapter.

Can you put an auger on an excavator?

Yes, provided the machine has an auxiliary hydraulic circuit and a mount the auger can bolt or pin to. This head is rated for 6-40 GPM and drives the bit through an Auburn planetary drive, with 3/8" thick steel construction and Parker hoses, fittings and couplers. Confirm both flow and mount interface against your machine before ordering.

What are the different types of auger bits?

Earth or dirt bits with cutting teeth cover ordinary soil. Rock bits use carbide teeth for shale, caliche and hardpan. Tree and nursery bits are shaped to lift soil out cleanly for planting. The shaft interface matters as much as the tooth type: this auger uses a 2" hex output shaft and takes bits from 4" to 48" in diameter.

What are the common problems with mini excavator attachments?

Most trouble traces to flow mismatch, mount mismatch or neglected hydraulics. An auger starved of flow stalls under load, and one fed above its rated range works the motor harder than intended. Leaks usually start at chafed hoses and couplers rather than the drive. Check planetary oil, grease on schedule, and replace worn teeth before they damage the flighting.

Q: Do I need to locate utilities before augering?

Yes. OSHA 1926.651 requires employers to determine the approximate location of utility installations, including sewer, telephone, fuel, electric and water lines, before opening an excavation, and to have the utility owner mark them. In the US that request goes through the national 811 call-before-you-dig service. Verify any marks near your hole before the bit turns.

This mini excavator auger page carries one attachment: the Loflin Fabrication Mini Auger at $3,638. It takes 6-40 GPM of auxiliary hydraulic flow, turns 4" to 48" bits on a 2" hex output shaft, and is built from 3/8" thick steel around an Auburn planetary drive. Listed mounts cover Toro Dingo and Bobcat MT50, 52, 55, S70 and RC30 carriers.

Mini Excavator Auger Attachments: What Is in This Category

This category lists one unit, the Loflin Fabrication Mini Auger at $3,638. It is a hydraulic drilling head built around an Auburn planetary drive, with Parker hoses, fittings and couplers, 3/8" thick steel construction and a powder-coated finish. The output shaft is a 2" hex, the industry-standard interface, so it accepts common bits from 4" to 48" in diameter. Rated flow is 6-40 GPM, a wide window that is the main reason this head suits a range of small carriers rather than one specific machine.

Will an Auger for a Mini Excavator Fit Your Machine?

Two things decide fit: hydraulics and the mount. Your machine needs an auxiliary circuit delivering flow inside the 6-40 GPM band above. Starve the head and it stalls in dense soil; feed it past its rating and you are working the motor outside what it is built for. On mounting, the listed compatibility is Toro Dingo and Bobcat MT50, 52, 55, S70 and RC30 interfaces, which are compact tool carrier and mini track loader mounts. If you run a true mini excavator with a pin-on or quick-coupler stick, plan on an adapter that matches your coupler, and confirm that interface before ordering rather than after.

Bits, Ground Conditions and Upkeep

The head is half the job; the bit does the digging. Earth bits with cutting teeth handle ordinary soil, rock bits with carbide teeth work shale and hardpan, and tree or nursery bits lift soil out cleanly for planting. Diameter drives torque demand, so the 48" end of this range asks far more of the machine than the 4" end. Size the bit to the hole you actually need, not to the largest one the shaft will take.

Before drilling, OSHA 1926.651 requires employers to determine the approximate location of utility installations such as sewer, telephone, fuel, electric and water lines before opening an excavation, and to have the owner mark them. Upkeep is short: grease the drive on the manufacturer's interval, check planetary oil level, inspect hoses and couplers for chafe, and replace teeth before they wear into the flighting.
