Schmism,
I understand what you are saying about today's steel prices, but steel is not quite as expensive here as there I believe. There are very few tractors here in Poland that are under 20
hp and therefore, the implements that go with these tractors also are few. I think that there are plows, and mowers available, but not other ground engaging tools that are so common in the States.
As to my welding--who told you!!!

Actually, I worked summers as a heavy equipment mechanic to put myself through college and grad school. So I have used the best of welders and the worst. I do not consider myself a welder, but I can weld--that is what the 4 inch grinder is for--to clean out the bird dodo so that I can weld it again!
Darkviper, Design is a hard thing that I have to continually remind myself that this implement does not have to withstand a D-8h just a 1510D yanmar--a bit of a difference.

But I copy well. If you look at the dirt scoop that I made--Homebrew mentioned it--you will see a remarkable resemblance to the KK scoop. That is not an accident.

I have studied the manual and pictures that I can find of the Gannon and think that I can scale it appropriately for my uses. I am not inventing I am imitating.
On that note--does anyone know how the scarifiers are retained on the Gannon?

This is a puzzle for me. I have never seen one in real life, just pictures and that part seems not to have drawn the photographers attention.
Thanks,
Mike in Warsaw
