How to Sharpen Stump Grinder Teeth?

When it comes to stump grinder teeth, then we must ensure that they are sharp enough, so that it can grinde out the stump of trees easily. Removing trees will be helpful to finish the landscaping for a smooth, level area. It also helps to stop roots growing. When the stump grinder teeth are dull, the machine will not cut efficiently into the stump. This can cause damage to the stump grinder or injury to the operator. It is best to keep the teeth sharp through grinding.

Step 1: Remove Spark Plug

The best way to ensure that you are not hurt by some mysterious accident is to remove the spark plug from the stump grinder. This way, you will not need to worry about someone accidentally starting the stump grinder while you are working on the teeth. 

Step 2: Remove Teeth from Grinder

Each of the teeth on the stump grinder must be removed in order to sharpen them correctly. The individual teeth are attached to the blade through the use of very small set screws. Use a screwdriver and loosen the set screw. Remove the tooth from the blade. If you have a lot of work to do with the grinder, it is best to have an extra set of teeth already sharpened. This way you do not have to rush, and you can remove all of the stump grinder teeth at once. 

Step 3: Set Up Work Space

Working with a grinder demands some precautions when it comes to your work surface. Make sure it is clean of any dirt and debris. Any small particles can catch on fire through the sparks from the grinding of the metal. Also, make sure the area is clear of any flammable liquids. Set the grinder up with the metal wheel on one side and the green wheel on the other. 

Step 4: Start With Metal Wheel

Set one of the front plates on the grinder to a 120-degree angle. Turn on the grinder and start to grind the shank of the tooth. Continue to do this until you actually reach the carbide itself. Continually remove from the grinder and cool of in some water. If allowed to get too hot, it will scorch the stump grinder tooth and it will be no good. 

Step 5: Use Green Wheel 

After you have done the work on the metal grinding wheel, you will need to move to the green wheel. This is a grinding wheel that is diamond impregnated so that it can grind the carbide of the tooth. The face plate should be set at 90 degrees. Grind the carbide tooth by gradually working it against the grinding wheel. Do not let it come in contact with the shank. Again, use water to cool off the tool. 

Step 6: Blow Off Dust

Once all of the stump grinder teeth are sharpened, blow them off with some compressed air. This will remove all of the dust and metal shards. After they are clean, then give them a light coating of machine oil so that they do not rust while being stored.
