Feller Buncher Teeth: Maintenance & Replacement to Reduce Downtime

2025 06/19

Why Tooth Maintenance Matters

Feller buncher teeth are critical for efficient tree cutting. Worn teeth cause:
 
 · 30%+ productivity loss
 · Increased fuel consumption
 · Damage to cutter heads
 

4 Essential Maintenance Steps

1.Daily Inspections
  · Check for cracks, blunt edges, or missing carbide
  · Measure wear against OEM specs (replace if >30% height loss)
2.Clean Properly
  · Pressure-wash after use to remove sap/soil
  · Use citrus solvents weekly to dissolve resin
3.Sharpen Correctly
  · Sharpen steel teeth at 15° edge angle
  · Never sharpen carbide teeth – replace them
4.Prevent Corrosion
  · Apply dry lubricant to bolts
  · Store spares in dry conditions
 

When to Replace Teeth: 3 Key Signs

1.Chip Size Change
Sawdust instead of chips = dull teeth
2.Excessive Vibration
Indicates missing teeth or uneven wear
3.Visible Damage
Cracks, bent shanks, or >50% carbide loss
 

Tooth Replacement: Quick Guide

Tools Needed: Torque wrench, impact driver, anti-seize compound
Steps:
1.Relieve hydraulic pressure + lock cutter head
2.Remove bolts with impact driver
3.Clean mounting pockets thoroughly
4.Install new teeth with anti-seize on bolts
5.Torque to 90-120 ft-lbs (check OEM specs)
6.Test at low RPM for balance
