Stump Grinder Question?

**cjohnson** · 06-19-2003, 08:25 PM

I was wondering if anyone knows if a stump that someone has tried to burn twice will be any harder on my stump grinder teeth than a normal stump? Any suggestions would be appreciated.

I had a customer who had to have a fire on the stump before i got there. Needed to drink I guess. It just makes more of a mess for you.

Some green hardwoods will fire harden considerably. It won't affect your stump grinder's teeth but it may make the job take longer-you tend to cut smaller chips each pass.

The stump in question is a willow and is about 128" across. Do you know if willow is one that will harden when burned? At that size the job would take most of a day if it gets hard.

What size grinder are you going to be using?

Yes, willow WILL fire harden but I have never ground one that had been fired. My guess is that it won't make a significant difference- The fired willow sticks I've messed with surface hardened a little but was still pretty soft below the surface.

I have a stump grinder that attaches to a skidloader they rate it at 60 H.P. and it has a 21" grinding wheel. I figure it would take 2 to 21/2 hrs to grind that stump and clean it up. You can see the stump grinders at www.ceattachments.com
