I bought a disc plow without even knowing what it was.

Thanks,

Just rustolium gray primer and Fleet Farm's JD green out of a spray can..

Not the most durable in the world, but price was right and my stuff is always stored indoors, so some nicks and scratches are ok.

Just bought an old 2-bottom moldboard to adapt to trenching for a waterline by removing one bottom. But the 1/2 mile long line runs through woods and brush and I expect lots of snagging on roots. Now I realize that a disc plow would be better suited for this task. I recall my father used one for years in areas that people wondered how he broke the soil in cut-over timberland.

Now I see that you own a Shaver SC50 stump grinder as do I. Do you think it's possible to make a 2x10 inch trench for my 1-inch pipe by dragging this stump grinder? I fear I would tear up the PTO if I tried.

If I had it I would just grease the grease points and park it so the blades were not in the dirt. If ever needed just hook it up and go.

Ours ( in the 60s ) was called a " Texas Graham Home " plow. The two discs were hard to keep in the clay / rock soil. Pulled it with a ford major diesel so no hp problems. It didn't work out so it sat at the field edge rusting away. I think they worked best in sandy soil. They may cut tree roots but it rode on the ground surface more than in the soil due to no down pressure on the three point.

I used a similar plow about 15 years ago to clear tree stumps and roots from a pasture that had become overgrown. The field was full of small tree and bush stumps, up to maybe 3 inches in diameter. The plow with 2 discs did a good job turning most of them out of the ground, where we could walk through and pick up later. I pulled with a 2wd John deere 5200, which is a 40 HP tractor, in clay soils. Was worried a moldboard plow would break points or hang on the roots. The discs seemed to either flip the stumps out of the ground or cut through them below the surface. Not sure I have used the old plow since then. It did seem to leave the ground pretty rough, but that might have been a touch of me not having it set up exactly right.......

Have never pulled a normal breaking plow with this tractor, so can't really compare to how it would pulls versus a moldboard plow.

Ive thought about that as well, but I think for a long run like that it might be pushing your luck. I would say if you are planning on replacing the teeth soon anyways then give it a try. You really can't hurt the stumpgrinder from what I've seen, but if you hit any good size rocks then you may break some teeth. Just 4 or 5 teeth would probably cost the same as renting a ditch witch or similar.
If you do try it, let me know how it works. I don't think I would if I were in your situation though.
