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.
