BIG DAVE

💪 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
