Stump Grinder Build

[woodlandfarms]

Yeah, there is a lot of things left to do. I need to trim the front shaft down, but wanted to wait until I was sure about the motor / machine combo in case I had to move stuff around. I also need to build a cover over top of the wheel (not much debris but some comes up).

The interesting thing is the Greenteeth. I was expecting chips and lots of them. Instead I have sawdust. It makes for one heck of a mess if the wind is blowing the wrong way. i was coated last night in wood dust. I am thinking about some sort of flap to keep the debris down.

I'm impressed with your machine! Good job!

Carl,

What is the number stamped on the teeth? 5, OR 7, OR 9

You should be getting chips or shredded material.

Do you have a hyd gage in the circuit to see the running pressure.

I recomputed the 4.6 cu in hyd motor HP, and it came out to about 20.

Do the rpms hold steady as you sweep across the stump?

When can we see the video?

Hmmmm. It is the 700 Lo Pro series. I do have a guage, but have not put it into series yet. I got 37HP at 3000PSI and 18GPM. I don't run the engine full tilt but...

So it was my first time. Past two days we have had rain. My plan is for tomorrow to get out and continue playing. Will get the camera out as well.

Looks like he cut across the end of the grain on top of the stumps. Only way a small stump grinder will make chips is if you attack them from the side and cut with the grain.

Thanks mr he. Just found out I was skimming the tops and I can take a big bite with this. Walnut stump was gone quick tonight. Tomorrow will video some maple stumps

Video of the bad boy in action. Alder stump maybe 6 months old. Tree was in bad shape to begin with.

Next week I cut the shaft down and put on a protective cover and flap.

Oh, I added a second quick attach plate. This allows me to turn the machine sideways (or normal for most grinders) and I can trench with it. Trench runs about 10" deep, problem is the dirt disappears, so no way to cover it up.

Looks real good. Cutting nice for the size of it.

Looks good! RPM doesnt seem to slow.

I'm getting the inspiration to build my own this winter... 3pt hitch mounted, with the 100hp gearbox of an old straw chopper. What teeth did you use, are they universal (brandless) or specifically for a brand of cutter ?
