Typically, there should be no less than one inch and no more than three inches of slack in your trencher chain.

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.

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.

Virnig offers three boom sizes, 36”, 48”, and 60”. Your trenching needs will be the main factor to decide the depth needed. 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.

Comparing standard flow and high flow, generally speaking, higher GPM is better. Higher GPM provides more torque which allows the trencher to continue turning the chain and stall less. The best results will be yielded when pairing the trencher motor with the skid steer’s optimal flow rate. For more information, contact your local dealer or Virnig at 800-648-2408.

Each chain works best in different soil types. The wrong chain type can make a great trenching unit perform poorly.

Single Standard- Cup tooth every other station. Works best in soft to medium soils. Also works well in sticky soil since there is more space between teeth to limit clogging/clumping.

Double Standard- Cup tooth every station. Works best in soft to medium soils. Also works well in sandy, dry soils. The additional cup teeth keep material moving out of the trench instead of falling back in.

Terminator- 50% cup teeth, 50% shark-style teeth with embedded carbide inserts. Works best in soft to hard soils, as well as rocky soils. The terminator chain is the “catch-all” style. If you will be working in both soft and rocky soils this is the chain to get. If working in primarily one or the other a more specialized chain may work better, but the terminator works in almost any soil type.

Rock and Frost- 50% Cup teeth, 50% replaceable carbide tip rock teeth. Works best in rocky soils, as well as frost. The carbide tips spin as they hit rocks for even wear and increased longevity. If the soil to be trenched requires going through and breaking up smaller rocks this is the chain to use.

Virnig offers 6”, 8”, 10”, and 12” wide chains in a number of configurations. See the spec table for specific options.

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

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.

The motor flow rate should be optimized to match the skid steer’s flow rate. These are measured in gallons per minute (GPM). Running a higher GPM than the motor is rated for can potentially damage the motor and will void the warranty. All Virnig skid steer attachments with hydraulic motors have a zero overflow rating to prevent premature failure.

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.

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.

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.

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.

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.

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.
