Maintaining the teeth on your stump grinder is crucial to keeping your stump grinder in tip-top operating condition. Inspection and replacement should be a part of your regular maintenance routine.
Barreto Stump Grinders are factory equipped with Greenteeth LoPro® pockets and Greenteeth Wearsharp® cutter teeth. We offer these sets in 500, 700, and 900 series. These cutter teeth are equipped with three cutting edges, allowing for increased longevity. The following instructions will illustrate how to rotate and replace these teeth to take advantage of each cutting edge.
If you are visibly noting wear (chipped or broken teeth, rounded edges), or noticing decreased performance from your Wearsharp® teeth, it is a good indication it is time to rotate them. Due to the high wear nature of these parts, and the vibration they are subjected to, we recommend you inspect your teeth after each use and check all fasteners weekly at a minimum.
Recognizing Wear and Damage
A visual inspection can tell you a lot about the condition of your cutting teeth. Worn teeth will look dull and have a rounded edge. You may see chips in the tooth, or even notice a broken or missing tooth in extreme cases. If you see missing teeth or broken pockets, Immediately replace these parts. As this can cause premature wear to bearings and other essential parts.
