Below are various questions Virnig Manufacturing receives on a regular basis. Browse through the following questions and click on a question to see the answer. If you do not see your question listed below please contact a local Virnig dealer or call 800.648.2408.
The X30 Mini Excavator Brush Cutter is compatible with many of the 40, 50 and 60 class size excavators. The mini excavator must weigh more than 8,900 pounds to operate the X30 Mini-Ex Brush Cutter safely. Also, the excavator must be rated with enough lift capacity to safely maneuver the cutter at full reach. Consult excavator manual or dealer for reference.
The X30 Mini-Ex Brush Cutter doesn’t have a max excavator weight rating since cutter motor flow rate goes up to 25 GPM and most of the midi and standard size excavators are above 25 GPM. It probably isn’t the optimal cutter for a standard size excavator since they have a lot more hydraulic horsepower and lift capacity to use a larger cutter.
It’s highly unlikely the X30 Mini-Excavator Brush Cutter motor, with a max capacity of 25 GPM, can handle the auxiliary flow output of any standard size excavator. Virnig motors have a zero tolerance for overflow, and using attachments at higher-than-rated flow rates can lead to catastrophic motor failure and additional stress on the bearing spindle.
The X30 Mini Excavator Brush Cutter motor is compatible with excavators with an auxiliary flow rate of 15-25 GPM. Not to be confused with the total flow rate of the excavator pumps, auxiliary hydraulic flow is the flow rate output down the boom and arm to the primary hydraulic circuit which powers the attachment.
No, the X30 Mini-Ex Brush Cutter doesn’t require a case drain line. The relief valve in the manifold relieves excessive hydraulic pressure. Most mini excavators don’t have a case drain hookup and retrefitting one is time consuming and expensive.
The X30 Mini Excavator Brush Cutter utilizes an Eaton® Geroler motor which is made in the USA. These motors have a proven track record of delivering superior performance and longevity. Geroler motors are less susceptible to contamination and cavitation compared to piston motors, making them more durable. Furthermore, they are more cost-effective to replace than their piston counterparts.
Also, piston motors require a case drain line which is expensive and time consuming to add to an excavator. The X30 Mini Excavator Brush Cutter doesn’t require a case drain line. The relief valve in the manifold relieves excessive pressure.
No, the cutter flywheel will spin for up to a minute before it comes to a complete stop. Never exit the cab until the flywheel comes to a complete stop.
A pressure relief valve protects the motor and the loader’s hydraulic system from damaging pressure spikes. When the maximum pressure point is reached, the valve opens to prevent pressure from rising any further. This prevents seals or other internal components from failing due to excessive pressure.
The X30 Mini Excavator Brush Cutter is specifically designed to spin and cut in the counter-clockwise direction. Attempting to run the cutter flywheel in the opposite direction (clockwise), will result in subpar performance. The cutter will have difficulty sustaining operation, with a higher likelihood of stalling and torque will be reduced by about 75% compared to operating it in the counter-clockwise direction. It’s crucial to use the X30 Mini Excavator Brush Cutter correctly to ensure optimal results and avoid potential damage.
No, the mini excavator is designed to operate and spin in one direction (counter-clockwise). One-way auxiliary hydraulic flow is needed to operate the X30 Brush Cutter.
The maximum operating pressure is 3500 psi.
The spindle is the most expensive performance component on an excavator brush cutter. It is responsible for smoothly transferring power from the hydraulic motor to the flywheel and absorbing impact that could damage the hydraulic motor.
High-performance skid steer brush cutters require heavy-duty spindles to ensure reliability and productivity. X30 Mini Excavator Brush Cutters are equipped with USA made bearing spindles.
Virnig has various pin grabber and wedge style hanger brackets available to fit most mini excavator brands – like Kubota®, John Deere®, Bobcat®, CAT® and more. Hanger brackets can be ordered with or without machined pins.
All Virnig hanger brackets have an Epiroc Hammer bolt pattern with six holes. It’s one of the more common hole patterns in the excavator industry.
The X30 Mini Excavator Brush Cutter is using a high torque Eaton® motor and heavy flywheel system with three blades for more rotational energy to power through thick brush and 4” diameter trees. Virnig cut capacity is what diameter material an operator can efficiently cut without getting frustrated with performance & durability.
The Virnig X30 Mini Excavator Cutter was the preferred choice over many of the major brands on the market during testing, largely due to higher performance, deck configuration options and not needing a case drain line.
All excavators share flow with the other excavator functions to some degree and it differs depending on machine. All brands respond differently when operating attachments, based on operating pressure, flow rate, number of pumps and pump type. Some mini excavators utilize a single hydraulic pump, which means any multifunctioning while using a powered attachment (raising/lowering boom, traveling) is likely going to slow production.
The mini excavator’s powered attachment and movement rely on the same hydraulic oil coming from the pump(s), which can limit performance. When a bucket is in use, the undercarriage and boom can utilize full hydraulic flow, ensuring the excavator’s movements are not compromised. However, when operating a powered attachment, like a brush cutter, the extra hydraulic oil needed to run the cutter may decrease excavator ground speed and cycle time when booming up or down. Booming up is usually more impacted than booming down.
Mini excavators usually lack the hydraulic flow and horsepower of a skid steer, until the standard (10-ton) excavator size range. Even with the mini excavator at rest, the primary auxiliary circuit often cannot produce hydraulic flow rates exceeding 25 GPM. Consequently, cutting performance is unlikely to match that of a skid steer.
All Virnig cutters have USA-made blades, which are forged using American 5160 spring steel and are heat-treated for high impact toughness.
It depends on the material and where you’re cutting.
Here’s what Virnig recommends:
It’s relatively easy. A side curtain can be detached by removing eleven nuts and bolts. Each side weighs 65 lbs.
To access the teeth for replacement, you need to remove 6 bolts on the bottom of the flywheel and take off the flywheel. Please note, the flywheel weighs 145lbs. Flywheel removal instructions can be found in the operators manual. It may be faster to leave the flywheel installed and use a crowfoot wrench if only a couple teeth need to be replaced.
Provided there’s a hanger bracket suitable for the excavator it will be mounted on, the cutter is ready to use. The cutter includes 90” hoses and ½” couplers. However, if it’s being attached to a long arm excavator, the standard 90” hose length may be too short to reach the excavator’s auxiliary hydraulic circuit.
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.

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.

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.
