PTO Stump/Tree saw

How much did the blade cost.

900.00 to my door, with a spare set of carbide inserts.

That looks like a nice peace of machinery. What make and model was the discarded brush cutter? Is the main part of the blade mild steel?

The mower was a MG 10 Sidewinder. We had torn up 3 center T Gear boxes by hitting stumps, so got tired of replacing gear boxes.
The 90 degree gear boxes are 75 HP rated, 1 to 1.46 increaser ratio.

Not sure about the grade of steel. We talked to someone else who had built one & he said these people were knowledgeable on the wheels & he was happy with his. We liked his price, so just went with him.
We have probably put 8 to 10 hrs on it so far & have not rotated any tips.

looks mean... i bet you lock up pets wife and children in the house before using it..

You definitely do not want anything near that could get hit. I did fail to mention, I would sure want a cab or some other form of protection. When cutting through a tree, most chips go to the side, but if you take another pass to lower it one inch or less, chips are hitting the cab heavily.

Thanks for the response. I could really use one of those.

I reckon you need to beef up the side plating on that. The energy in 4+ foot of 1/2" plate rotating at 540 rpm is mind boggling. Do some sums, but I reckon you'd need at least 3/4 plate around it rather than the 1/4 stuff it looks like. At the moment if that gearbox output shaft let go people in Mexico would be saying "What the F*ck was that!"

That is the scariest thing I have ever seen...

It does have lots of momentum. I have cut a 1-1/2" then moved & cut a 3" tree after disengaging the pto. It does slow down very fast (and can even bog the engine down) when it engages the ground, much like a rotary mower. It has two layers of steel between it and the tractor on the front side, and on the rear side it is below all the steel, so I can cut below ground level. Normally we are 1/4 mile away from any living beings.

And will likely remain so if that monster starts throwing chunks at dwellings! Way cool!

very nice use of being able to multitask an implement can you possibly send me some info on how to change my bush hog this way if its not too much trouble?
