Mini Auger Drive Attachment- Blue Diamond

📘 Overview

The Blue Diamond Mini Auger Drive is a compact skid steer auger drive that powers earth augers for drilling holes on mini machines. It mounts to a universal mini skid steer or Bobcat MT quick-attach interface, pairing a high-torque manufactured gearbox with a two-piece shaft designed for maximum side-load ratings.

This listing covers the Extreme Duty Series 2 mini auger drive, sized for compact carriers. Auger bits, extensions, and adapters are sold separately, so you build the exact drilling setup your job needs — from fence posts to deck footings.

As a mini auger drive skid steer operators trust, it brings serious drilling torque to compact machines. The blue diamond mini auger drive uses a manufactured (not cast) gearbox for durability; as a mini skid steer auger attachment it fits mini universal and Bobcat MT mounts. The mini auger extreme duty series 2 design is backed by a 5-year gearbox warranty and 3-year motor warranty.

The compact high-torque gearbox, two-piece shaft for side-load strength, and universal mini/Bobcat MT mounts make it a durable drilling drive for compact equipment. It operates at 3,000 PSI.

📊 Skid Steer Auger Drive Specifications

🔗 How the Mini Auger Drive Works

The auger drive mounts to your mini machine's quick-attach plate and connects to the auxiliary hydraulics. The high-torque gearbox turns an auger bit (sold separately) to bore holes for posts, footings, trees, and anchors. You choose the bit diameter for your hole size, add extensions to drill deeper, and use adapters to match the bit to the drive's output shaft. The two-piece shaft absorbs the side loads that occur when a bit binds or you drill at an angle, protecting the gearbox. Operating at 3,000 PSI, it delivers consistent drilling power for repeated holes across a job.

🔗 Attachment Compatibility

This mini drive accepts auger bits via its 2″ hex output shaft. Blue Diamond bits and tooth kits that use the 2″ hex interface fit this drive and are sold separately.
