Trencher

[Nightrain1]

I would like to see that in action. One thing looks to me will need more fabrication, is the ends of the trenching wheel. Something angled with more of a point to go in the ground. Maybe something on every other arm to dig and then the square pieces left on the other arms. I just don't see the squares on the wheel going in the ground but who knows, it just might work.
Either way, I envy your capabilities of building something like that!!

I have seen these in action and it was about 8' diameter and when it hit big rocks it jumped about 1' but it does break them pretty shortly after. It is also a fairly scary machine to watch.

I've never seen a saw used for much trenchwork,mostly seen them making cuts through road surfaces.
Buddy...I ain't in the habit of criticizing anothers fellas work....but please don't have the wife or kids watching when you try that out.Hope you have either shear pins or a slip clutch in there,she comes loose and you are gonna loose a tranny.

ya execpt theres one HUGE diffrenace..... the Ditchwitch version seems to be made from ONE solid plate of steel with attached cutters.

which wouldnt be a bad way to go if you could figure out how to attach teeth on it to dig a 4" wide trench....(or more)

Use a shear pin...or seven

I think a good rule of thumb for build it yourself is to copy an established design, but use more steel.

One option for a ditcher would be to find a salvage ditch witch and get the bar, chain, and gearbox off.

Be careful of yourr PTO clutch. They cost a lot to have replaced. Perhaps more than a used ditcher.

Please get the video camera on it when you first use it. We need to see this thing mangle. It will be fun to see. Maybe you can make money on it. I will pay $1 to see it.

LOL you guys crack me up

I gotta say, you hit a rock or God forbid a tree root and I have to think it's game over.
