Stump Grinder

[woodlandfarms]

I really want to build one. Still working out the details in my head before it goes to paper but the 1850 stump grinder is underwhelming in my book. I don't like the idea of welded on teeth to begin with and the wheel seems thing for a 65HP power source.

Then again, me construction something with a spinning wheel and sharp blades that is set directly in front of me is about as smart as me piloting a space shuttle. It will be cool to look at but the ending will no be pretty.

Most of the grinders are rotating wheels with teeth. What about a rotating cylinder with teeth instead. In other words, something that cuts a 10 inch swath instead of a narrow swath?

With respect to PTs, the limiting factor is hydraulic horsepower. Spreading it out over a wide swath might work out to a stump sander instead of a stump grinder.

Yeah, there is that. I need to learn to pay attention to what machines people have.

I can definitely stall my stump grinder and still have the engine run.

Eating my words here -

Cutting the old hard asphalt today stalled the stump grinder repeatedly without stalling the engine. I have no idea what has changed since I last used the stump grinder. It chewed through the pavement on Monday with no problem, but today it had a hard time. Today was like taking a jackhammer ride. It may be nothing more than how well the pavement was compacted in different areas.

Did you use the same speed/throttle setting as the other time?

Was it colder?

Your carbide teeth might be getting dull, and they will hammer on that asphalt real good. They can be sharpened using green color grinding stones, Be sure to keep the backside beveled. The cutting edge should be wider than the back of the carbide teeth.

My stump grinder is 10 years old. I am sure it needs sharpening. I an not sure how to sharpen it from your description. (I think I do just not sure) I don't want to ruin it. Do you know of a pictorial description?

Bob,

Dress up the contour of the face, round square or whatever. The back side of the tooth needs to be tapered from the face edge to the back.

This is a round carbide tooth, but notice the taper from the face to the back.
