Auger Drive Frequently Asked Questions

WHY DOES VIRNIG USE A PLANETARY GEAR REDUCTION SPINDLE OVER CHAIN DRIVE?

Virnig uses planetary gear reduction to transfer power from the motor to the output shaft and bit. Using a planetary provides several advantages over chain drive augers, including:  

Increased Torque: Planetary typically provides higher torque output, which helps power through harder soil. 

Greater Efficiency: Planetary reduction offers greater efficiency compared to chain drive. More of the power is translated into torque at the auger bit. This provides faster drilling times and lower fuel consumption.  

Reduced Maintenance: Chain drive augers require regular maintenance to keep the chain properly tensioned and lubricated. In contrast, planetary reduction systems require less maintenance and have fewer parts that will wear and break over time. 

Longer Lifespan: Planetary reduction auger drives tend to have a longer lifespan than chain drive augers, due to the reduced wear and tear on the drive system. 

Overall, planetary reduction can offer greater drilling performance, efficiency, and longevity compared to chain drive augers. 

WHAT ARE THE ADVANTAGES OF HEX OUTPUT?

Hex augers have a hexagonal shape, which provides better torque transfer from the drive unit to the bit. This means hex augers can handle higher loads and are less likely to slip or strip compared to round output augers.  

Hex augers have a more stable connection to the drive unit, which helps to reduce wobbling during operation. This results in smoother operation and more precise digging.  

It’s easier to attach and detach auger bits on a hex drive. A round drive requires aligning two circles properly. Also, Virnig Augers with hex output secure bits with a pin, which is easier to attach and remove than a bolt and nut used on round auger drives. This reduces downtime and increases productivity. 

WHY WOULD SOMEONE CHOOSE AN AUGER WITH ROUND OUTPUT?

Someone may choose round over a hex auger drive for several reasons. Round auger drives have been around the longest and switching to hex would require replacing all their round bits with hex collar bits. In some applications, hex may not be necessary and a round auger drive may be sufficient. Some users may simply prefer the feel of a round auger drive and may have more experience using them. 

Overall, both round and hex auger drives have their advantages and disadvantages, and the choice between the two will depend on the specific needs and requirements of the user. 

WHAT AUGER BIT TOOTH OPTIONS DOES VIRNIG OFFER?

Virnig offers Wisdom Gage teeth, Wisdom teeth, and Carbide Wisdom teeth for all purpose applications. Standard Chisel teeth and Carbide Chisel teeth are available for hard, more compacted ground. Standard replacement Fishtail Points and heavy-duty Carbide Fishtail Points are also available. 

HOW DEEP CAN I DRIVE THE AUGER CAN INTO THE HOLE?

The AUG30 and AUG36 drill 16-3/4” deeper and AUGHT36 drills 18” deeper than the cross hole on the planetary shaft before interference occurs with the cradle. However, a 12” diameter bit is necessary to bury the auger can beneath the ground surface, with the cradle being the first part of the frame to experience interference during drilling. 

DOES THE VIRNIG AUGER DRIVE USE A HEX OR ROUND OUTPUT?

The AUG30 and AUG36 are available with a 2” hex or 2-9/16” round output and AUGHT36 comes with a 2” hex output. 

CAN I USE THE AUGER DRIVE WITH HIGH FLOW?

The Virnig Auger Drive (AD36) motors are rated for 15-25 GPM with zero overflow tolerance. Operating higher than 25 GPM will void the warranty and can cause catastrophic failure. 

WHAT IS THE MAXIMUM SIZE AUGER BIT THE AUGER DRIVE CAN USE?

For best drilling results, the Virnig Auger Drive (AD36) is designed to use bits up to 36” in diameter and up to 48” long. Using a larger or longer auger bit can damage the spindle or motor and will void the warranty.

ARE VIRNIG AUGERS CROSS COMPATIBLE WITH DIFFERENT CARRIERS?

Certainly, with the appropriate hose length, mount(s), and adherence to the drive unit’s maximum operating pressure and GPM recommendations, Virnig auger drives can be easily transferred between a skid steer and a mini excavator by simply removing and reinstalling a pin. Contact Virnig for more info about auger drive cross compatibility between carriers.

CAN I USE THE AUGER DRIVE WITH HIGH FLOW? WHAT’S MAX PRESSURE?

The AUG30 motor is rated for 10-18 GPM, AUG36 motor 15-25 GPM and AUGHT36 motor 15-27 GPM. All motors have zero overflow tolerance. Operating higher than max GPM will void the warranty and can cause catastrophic failure.  

The AUG30 has a max operating pressure of 3,800 PSI. The AUG36 and AUGHT36 have a max operating pressure of 3,500 PSI. 

Virnig Frequently Asked Questions

WHAT IS RECOMMENDED LOADER CAPACITY?

Virnig attachments are rated to provide maximum performance and protection against damage when paired with an appropriately sized loader. Here’s a checklist to get the right attachment for your loader.

Go here to find skid steer capacity and specs.

Contact a local Virnig dealer for the most accurate attachment specs, or call Virnig at 800.648.2408.

HOW DO I PURCHASE VIRNIG ATTACHMENTS?

Virnig sells mini skid steer, compact tractor, and skid steer attachments through a network of independently owned dealers throughout the United States and Canada. Call 800-648-2408 for assistance in finding a dealer or use the online Dealer Finder.

WHERE CAN I FIND PRICING INFORMATION?

Please contact a local Virnig dealer to obtain pricing information.

For Virnig’s suggested retail price, fill out an online Request a Quote form.

WHAT TYPE OF ATTACHMENT INTERFACE/HOOKUP DOES VIRNIG USE?

All Virnig skid steer attachments are manufactured with a universal mount to fit most skid steer loaders. The mounting frame is built to ISO 24410 and SAE J2513 standards.

All Virnig mini skid steer attachments are manufactured with a Toro®/mini universal mount, Bobcat® mount, or ASV® mount.

WHAT IS THE SETUP TIME FOR A VIRNIG ATTACHMENT?

Most Virnig attachments are ready to work right off the pallet.

To minimize setup time, Virnig Manufacturing requires the machine brand and model to be listed in every order for attachments with hydraulic components. This ensures proper hose length, routing, and coupler sizing. In addition, all hydraulic Virnig Attachments are tested for leaks and proper operation before leaving the factory. There may be specific scenarios in which additional setup time will be required.

HOW QUICKLY CAN I GET REPLACEMENT PARTS?

Most parts for Virnig skid steer attachments are available in-stock and can be shipped as early as the same day the order is received. Fabricated and back ordered parts are available with a reasonable lead time. Virnig uses several shipping options to provide timely and cost effective delivery to customers.

Check with a local Virnig dealer for replacement part availability.

WHAT WARRANTY DOES VIRNIG OFFER?

All Virnig parts and attachments are warranted for one year from the end user’s date of purchase, or the dealer’s date of first rental/demonstration. If the warranty period has expired, a sales receipt or first rental slip will be required for warranty consideration.

WHY DOES VIRNIG USE NITROSTEEL® CYLINDER RODS?

Virnig uses NitroSteel® cylinder rods because they are a superior performing alternative to chrome plating. The finish offers improved corrosion resistance and better grease retention.

Chrome plated cylinder rods can flake or pit and destroy the seals or other internal components; resulting in downtime and expensive repairs.

A NitroSteel® rod will perform better and increase the service life of a cylinder, making it the cost-effective choice. Learn more about the benefits of the NitroSteel® process.
