Wanting to "cut" a slot in the ground

[dnw64]

A plow coulter would possibly do what you want. Cheap to try as used ones abound.

Would also be easy to mount to side of your bucket.

That looks like exactly the tool I need. Thanks!

I'm envisioning a disc that rotates, attached to the side of a bucket, so that when lowered and driven along, it makes a cut in the ground.

This would be to install edging, to keep a mulched area separate from the lawn, so I would want to go approximately 3-4" below grade.

Firstly, is there such a thing commercially available? I've done some searching but have no idea what it might be called. The closest I've found is a "pipe layer", but one key factor is that it needs to be at the side of the tractor. Between my son and I we could probably modify something if it was out there.

If not, any ideas/suggestions as to how one might be made? I have immediate use to install about 300LF of edging, and a lot more in the future, and don't look forward to doing this all by hand...

What you describe is used, a Pizza Cutter, to cut asphalt when attached to a loader bucket or grader mulboard. Smaller variations are used as a edger when doing mowing, at back of curb and sidewalk edges, attached to a tractor or veristraq. I dont know how big/deep you are wanting. If your thinking "trenching" you need more like a cable plow, preferably a vibratory, or rotary cable plow,

BTW, the 3 point I shared is expensive, due to weights and frame; there absolutely are commercially available ones that simply bolt onto the bucket.

I would call some commercial mower shops, as google/Amazon seem to be confused by the search... I see them routinely, and they arent "homemade"

Good point one of them would work, bet there used ones readily available
Just in case here is a random pic of one

I have one of those sitting in my shed taking up space....

This is pretty cool. I have a cordless edger that goes on a multiple-tool motor, but this would be faster.

Do you have a picture of this? It sounds like it might be what I need.

Thank you for that. How big (HP) of a tractor do you use to push that thing?

My machine is a 1500# front end loader, in a nutshell. It has a 25hp gas motor and everything is hydraulic. So maybe 12-14 HP to the wheels. I am fortunate that we have maybe 3-4" of turf soil on top of sand, so pushing it is not a problem, especially after a rain. I can angle it forward or backward with the dump/curl function and it's kinda like a weighted knife. I usually push the slit from point A to point B, then go back and it a rope to the hole on the bottom rear of the blade and us that to pull poly pipe in.

I also use it to edge my driveway if I let it go too long of a time and it gets too thick for the electric edger.

Last fall, I made something similar to it, but with two blades about 6" apart and a blade across the bottom. I used that to remove a strip of sod outside of our flower beds to plant bulbs in the trench it left. I don't have any photos of that, but will probably get some if I plant more bulbs this year.

This photo is from 2001.

You could easily make something similar for a 3PT hitch and pull it. The OP wants something offset to the side. I'd think that would be doable. Or maybe bolt something to the side of the bucket.

So, im still unsure, we want to cut a trench or edge? Those are different tasks. Edge, 24" smooth disc blade, some angle iron, a bearing (if we are fancy), and clamp to the side of the bucket.

If we want to trench; offset, we need to make a wide 3 point "tool bar" and attach something like a chisel plow to that. That's a lot of force of that tool bar though.
