🪓 HIGH-PERFORMANCE BLADE SYSTEM

Built to process material faster and leave a cleaner finish.

  • 3 double-sided blades
  • ✔ Up to 39 inches of active cutting edge
  • 2X more cutting edge than most 3-blade cutters
  • ✔ Machine-sharpened edges cut like axes
  • ✔ Efficiently processes material for a manicured finish

🛡️ SAFETY-FIRST DESIGN

Designed with operator protection in mind.

  • Hydraulic braking system stops flywheel within 10 seconds
  • Lift limit chain protects operator and machine

⚠️ SAFETY FIRST
DO NOT operate this cutter without a shatterproof cab on your loader. Serious injury or death can occur.


🛠️ BUILT FOR TOUGH JOBSITE CONDITIONS

Engineered for long-term durability and performance.

  • Replaceable front skid shoes for ground-level cutting
  • ✔ Glides over rough terrain
  • Angled rear deck corners improve material flow
  • Tapered rear deck runners reduce ground disturbance

🏗️ IDEAL APPLICATIONS

💪 BIG DAVE QUICK REVIEW: WILL THIS BRUSH CUTTER WORK?

No fluff—here’s what matters.

👉 Your machine either matches the cutter… or it doesn’t.


🔧 THE 4 MUST-CHECKS

1. QUICK-TACH

Must be standard skid steer mount (SSL).


2. OPERATING CAPACITY

👉 Use 50% of tipping load

Not brochure numbers.

  • Stay within min/max limits

3. FLOW (GPM) ⚠️

👉 Must be within range — NEVER over

Over =
❌ motor failure
❌ heat
❌ no warranty


4. PRESSURE (PSI)

👉 Must be at or below rating

Too much =
❌ blown seals
❌ shorter life


📏 WHAT WIDTH SHOULD YOU RUN?

👉 Wider than your tracks

BUT:

  • More width = more weight + more power needed

👉 Borderline machine? Size down.


⚙️ WHY SO MANY MOTOR OPTIONS?

👉 Flow = speed
👉 Pressure = torque

Every machine is different.

👉 Virnig gives motor options so you:

  • Match hydraulics
  • Stay safe
  • Get real performance

⚡ BLADE TIP SPEED

Higher speed = cleaner cuts

BUT…

👉 Mass keeps cutting

  • Light rotor = fast
  • Heavy rotor = keeps going in brush

👉 You need speed + torque + flywheel weight


🔥 WHY VIRNIG CUTS BETTER

  • Sharp blades (axe-style) = slice, not hammer
  • Longer edge (9.75"+) = more cutting per pass
  • Forged steel = stronger, longer life
  • Balanced flywheel = smoother, less shock
  • Uses more hydraulic power = less bogging

🧠 BIG DAVE TAKEAWAY

Most problems come from:
👉 Bad match
👉 Poor design


🔥 FINAL WORD

Get it right:
✔ Smooth
✔ Fast
✔ Long-lasting

Get it wrong:
❌ Expensive

👉 Match it. Size it right. Run it right.
