Skid Steer Augers & Auger Drives

When you’re doing heavy work in agriculture or construction, a skid steer loader is an excellent piece of equipment for getting jobs done. With Stinger Attachments, you can expand your skid steer’s capabilities for your jobsite. Tools like augers are great for carving out earth and rock to make room for pipes and wiring.

We offer powerful auger drives and augers so you can find the American-made attachment that’s right for your digging job.

  • How to Choose the Right Auger for Your Skid Steer

    Choosing the right auger drive for your skid steer is a critical decision that impacts your productivity and bottom line. Boosting your technical knowledge can help you match a high-performance auger drive to your machine and the job’s demands.

    Understanding the Core Components

    The two main components of an auger system are the drive and the bit. The auger drive consists of a hydraulic motor and a planetary gearbox that provide the torque to get the job done. The auger bit is the consumable attachment that drills the hole.

    While proper on-hole diameter and soil type determine bit selection, the drive indicates if you have the power to turn that bit through heavy resistance. That’s why you always choose the drive first.

    GPM and Torque

    Your skid steer’s hydraulic flow, measured in gallons per minute (GPM), determines the auger’s rotational speed. Most skid steers have a standard-flow system (typically 15 to 25 GPM), while larger machines may have a high-flow option (28 to 45+ GPM). It’s crucial to match the auger drive’s required GPM range to your machine’s output to ensure optimal performance and prevent damage.

    While GPM dictates speed, torque (measured in foot-pounds) is the raw rotational power that gets you through tough ground like clay, rock or frost. For demanding applications, torque is far more important than speed. A high-torque drive, like Stinger Attachments’ planetary drive models, will power through resistance without stalling, where a lower-torque model would simply stop.

    Choosing a Planetary vs. a Direct-Drive System

    Stinger Attachments auger drives use a planetary gearbox instead of a direct-drive version, and for good reason. This system excels at converting hydraulic flow into powerful torque, ensuring greater efficiency and a longer lifespan. Unlike simpler direct or chain drives, a planetary system can handle heavy, repeated use and prevents common failures like shaft pullout, keeping you on the job longer.

    Frequently Asked Questions About Skid Steer Augers

    Enhance your knowledge by reviewing the answers to these typical skid steer auger questions.

    How Do I Match an Auger Drive to My Skid Steer?

    Start by checking your skid steer’s GPM output. Then, consider the typical ground conditions you work in to determine your torque requirements. Match these two factors to the auger drive specifications.

    What’s the Difference Between Standard and Extreme-Duty Auger Drives?

    The main difference is torque. An extreme-duty drive can accommodate higher GPM and deliver significantly more torque, making it suitable for larger bits and tougher drilling conditions, such as rock or compacted soil.

    How to Choose the Right Auger Drive — Flow Rate and Post-Hole Sizing Guide

    Before you browse the listings, lock in the hydraulic flow rate for skid steer auger work (measured in GPM) and the hole diameter your job requires. Get those right, and every other decision follows.

    Fit Your Machine’s GPM to the Right Drive

    The single most important decision is matching the auger drive flow rate to your machine’s output. A mismatched drive either underperforms or overheats your hydraulic system.

    Standard-Flow Machines

    Most of these loaders run standard-flow auxiliary hydraulics from the factory, typically producing 15-25 skid steer auger GPM. If that’s your machine, Stinger’s standard-flow auger drive is your fit.

    High-Flow Machines

    If your machine has a high-flow system — typically 28-45+ GPM — consider Stinger’s high-flow auger drive. You may experience faster rotation, more torque for rocky or compacted ground, and the muscle to run larger-diameter bits efficiently. When it comes to auger torque vs. flow, GPM drives speed, but torque through Stinger’s planetary gearbox is what punches through tough ground.

    Choose Your Bit Diameter for the Job

    Once your drive is matched, select the right auger bit for the hole.

    Fence Posts and Sign Posts

    Standard auger bit sizes for fence posts range from 8 to 10 inches. That post hole size for fence posts leaves enough room for a proper concrete collar and keeps your posts plumb without fighting the hole.

    Gate Posts and Corner Posts

    Gate and corner posts take more daily stress. Move up to a 10-inch to 12-inch bit so the footing has the width it needs to hold.

    Footings and Structural Piers

    For deck footings, pole barn piers or structural applications, start at 12 inches and size up based on load requirements and your local frost line depth.

    Auger Drive Flow Rate Questions and Answers

    Learn more about auger drive flow rates with these FAQs.

    What GPM Does a Skid Steer Need to Run an Auger Drive?

    A typical auger drive flow rate falls between 15 and 25 GPM. High-flow drives require 28–45+ GPM. Match the drive’s rated range to your machine’s actual auxiliary output. Find that number in your owner’s manual under “Auxiliary Hydraulics.”

    Is It Appropriate to Use a High-Flow Auger Drive on a Standard-Flow Machine?

    It is not appropriate to use a high-flow auger drive on a standard-flow machine. A standard-flow machine with a high-flow drive underperforms and risks overheating your system. Stinger’s auger drive comes in both standard-flow and high-flow configurations, so there’s a right fit for your machine either way.

    What Size Auger Bit Do I Need for Fence Posts?

    For a standard fence post, an 8-inch to 10-inch auger bit provides enough clearance for concrete and alignment. For gate or corner posts, move up to 10-inch to 12-inch.
