Stump Grinder

[Sidekick]

Carbide is brittle.

I have found with my cold cut metal saws that different grades of carbide have different lifespans and cut quality. Some chip away and destroy the tooth and some dull making them easily resharpened. Wondering if it is the same with these teeth.

The teeth have brazed carbide tips.

There are different grades of brazed carbide, e.g C3, C5, C6. That is important in metal cutting where you are cutting different materials and varying speeds.and feeds while attempting to maximze tool life. Some grades are a little tougher (less brittle) and are used for harder metals. But they are all much more likely to chip than HSS. I would guess that difference is not a big factor in makung brazed carbide stump grinder teeth.

So after doing two fairly large stumps I would say roughly 24 inches round each here are my thoughts. Overall I am very pleased with the unit if I were in the stump removal business this is not something I would use but for me with several acres and an occasional stump here and there it's perfect. A couple of suggestions strongly suggest installing a backup camera your neck will thank you. Second I had a mid mount mower on my machine and the next time I will probably remove it to use the stump grinder I left it on the first stump I did and on the second one I pinned it in the up position which was a big help the biggest problem with the mower deck was the two stumps I did we're on a slope and it seemed to interfere with the movement of the machine when I had to lower the grinder into the stump. Other than that well worth the money
