The Vermeer 665A is a powerful machine, but like any piece of heavy equipment, it requires regular inspection and maintenance. These five checks are crucial for maintaining its performance and ensuring your safety.

1. Cutter Wheel and Teeth Inspection: The Heart of the Grind

The cutter wheel and teeth are the business end of any stump grinder. They’re responsible for the actual grinding, so their condition directly impacts the machine’s effectiveness.

Why it Matters: Dull or damaged teeth drastically reduce grinding efficiency, increase fuel consumption, and put unnecessary strain on the engine and hydraulic system. Damaged teeth can also become projectiles, posing a serious safety hazard.

Step-by-Step Inspection:

1. Safety First: Disconnect the spark plug wire to prevent accidental starting. Engage the parking brake and chock the wheels for added security.
2. Visual Assessment: Carefully inspect each tooth for signs of wear, chipping, cracking, or damage. Look for rounded edges, indicating dullness.
   • Pro Tip: Keep a logbook of when you last sharpened or replaced teeth. This helps track wear patterns.
3. Tooth Security: Check that each tooth is securely fastened to the cutter wheel. Use the correct wrench (typically a torque wrench) to ensure bolts are tightened to the manufacturer’s specified torque.
   • Torque Specs: Consult your Vermeer 665A operator’s manual for the correct torque specifications for the tooth bolts. Overtightening can damage the bolts and teeth; undertightening can cause them to loosen during operation. Typically, these are between 60-80 ft-lbs, but always verify with your manual.
4. Cutter Wheel Condition: Inspect the cutter wheel itself for cracks, bends, or other damage. Pay particular attention to the welds and areas around the tooth mounting points.
   • Case Study: I once worked on a Vermeer 665A where the cutter wheel had a hairline crack near a weld. We initially missed it during a routine inspection. However, after a few hours of grinding, the crack worsened, leading to significant vibration and ultimately requiring a costly wheel replacement. This experience taught me the importance of meticulous inspection.
5. Tooth Rotation: Rotate the cutter wheel manually and listen for any unusual noises, such as grinding or scraping. This could indicate worn bearings or other internal problems.

Corrective Actions:

• Sharpening: Sharpen dull teeth using a specialized carbide grinder. Follow the manufacturer’s instructions for proper sharpening techniques and angles.
  • Tool Specification: I prefer using a bench grinder with a diamond grinding wheel for sharpening carbide-tipped teeth. A good quality grinder will cost around $200-$400.
