Virnig Auger Drive for Skid Steer

The Virnig Auger Drive AD36 is a high-torque skid-steer auger drive designed for contractors and utility crews tackling deep, large-diameter bores. It pairs a robust planetary reduction system with versatile output options to deliver power, efficiency, and long service life across tough soils. Output Options: 2" hex and 2 9/16" round output, supporting standard/tree auger bits up to 36" in diameter. Planetary Reduction: Planetary gear reduction transfers power efficiently from the Eaton hydraulic motor, delivering higher torque and better overall drilling performance than chain-drive designs. Bi-Directional Rotation: Allows convenient digging and rapid bit withdrawal, reducing cycle times on demanding jobs. Top Hose Routing: Hoses routed from the top of the housing to enable deeper drilling without hose interference. Motor & Protection: Eaton hydraulic motor with hydraulic pressure relief protection to safeguard the system under heavy loads. Bit Size Capability: Supports standard/tree auger bits up to 36" diameter; rock auger bits up to 18" diameter for challenging conditions. Model & Dimensions: Model AD36; Overall height 20.5", width 47.3", depth 35.5"; approximate weight 280 lb. Flow & Torque: Recommended flow 15–25 GPM; output torque ranges from 1,820 ft-lbs at 2,000 PSI to 3,190 ft-lbs at 3,500 PSI; output speeds of 54–81 RPM depending on flow. Versatile Use: Designed for skid-steer applications, ideal for installations of poles, fencing, and landscaping projects requiring large-diameter bores. This auger drive is engineered to solve real drilling challenges: higher torque to cut through tough soil, faster drilling times with efficient power transfer, and reduced maintenance thanks to a durable planetary reduction design. The hex output ensures a secure, low-wobble connection and quick bit changes, while the option for round output provides compatibility with existing equipment. With top-mounted hoses and bi-directional rotation, it’s a practical, reliable choice for heavy-duty auger work on a variety of job sites.
