V20 Mini Skid Steer Trencher Frequently Asked Questions

WHAT’S THE BENEFIT OF AN ANTI-BACK FLEX CHAIN?

In soft digging conditions, a standard digging chain excels. However, in compact or rocky soil, its design may lead to backflex. Backflex causes teeth to rotate backwards, which compromises the proper digging angle and reduces trenching speed. To overcome this challenge, the Anti-Backflex digging chain is purposefully engineered for demanding digging conditions. 

With closely spaced sides in each link, this specialized chain ensures a seamless connection as it leaves the sprocket, forming a robust digging channel. This innovative design guarantees that each digging tooth maintains the correct digging angle, providing not only superior trenching speed but also superior performance in challenging soil conditions. 

WHICH DIGGING DEPTH SHOULD I BUY?

Virnig offers two boom sizes 36” and 48”. Your trenching needs will be the main factor to decide the depth needed. Please note, the boom can be changed out later to change the depth. A new boom and chain would need to be purchased or chain links added to fit the new boom length.

HOW MUCH SLACK SHOULD BE IN THE TRENCHER CHAIN?

Typically, no less than 1” and no more than 3”.

CAN I RUN THE TRENCHER IN REVERSE?

Yes, it can run in reverse if needed. This can often help dislodge a rock or debris stuck in the chain. If the operator’s detent is not to their liking, they can swap couplers and change the direction of flow to match their preference.

WHAT KIND OF OIL IS USED IN THE SPINDLE?

All Virnig trenchers use 80W/90 gear oil in their spindles. Before each use and after 10 hours of operation the oil should be checked and added as needed. 

CAN I GET REPLACEMENT TEETH & PARTS FOR MY CHAIN?

Yes. There are replacement teeth and various parts available for all chains Virnig offers. 

WHY IS MY NEW CHAIN STRETCHING SO MUCH?

Stretching of new trencher chains is normal and should be expected. Most chains will experience approximately 80% of their stretching within the first 20% of their useable life. It will be necessary to tension the chain appropriately and may be necessary to remove a chain link in order to keep proper tension.

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.
