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
