Disc Harrow Newbie Question

[Spike56]

I would like to have some attachment to break up the top hard pan soil. What I am imagining (but, I do not know if something like this exists) is a set of knives / chisels ? I sold my 5 shank renovator some years ago. It was difficult to use for me (55 hp), the moisture level had to be perfect. Even then, it would raise clumps of clay in my hayfield.

So, is there something akin to the renovator, but instead of a large "foot" on the bottom, just a set of knives ? Just want to get down 6" and cut slits so IF IT EVER RAINS HERE, the water would be able to soak in better ?

:confused2:

The tool you need is a subsoiler. You can get a single shank that goes about 18". The the next pass have your tires on the furrow you just made. Works real well for what you are needing.

sounds like a box blade would work. 6-8 teeth depending on size. could drop 1 or all down 6" and get your grooves

You are in Texas where Miller-Hay King pasture renovators are manufactured. Perhaps a three shank or four shank model will work behind your tractor.

Pasture renovators are meant to be pulled through slightly dry soil so slits remain for water and fertilizer to penetrate.

Pulled through wet soil the slits close up.



How many acres do you want to work?

How deep do you want to penetrate?

Only concern with a box blade would be his achieving the 6 inches of depth that he wants.
You can gain a bit more depth with the BB scarifiers by going to the shortest length of your top link with the scarifiers set to their greatest depth.
At a 60HP+ tractor, you should be able to find an implement that should cut multiple channels in one pass. You are well beyond the size of my tractor so not sure what those might be. My other experience area is much larger commercial farming equipment. And you want to go much deeper than equipment in that arena other fully turning the ground, which is not usually desired in hay operations.

I pull a six shank scarifier. Depending upon soil conditions - I pull two, four or all six. Breaks the top soil very nicely.

Thanks all for the replies. I have considered the subsoiler, but was hoping to find something with multiple shanks. I had a hay king renovator previously - probably should have kept / used that and went shallower ? The problem was the foot would pull up big chunks of clay if the soil conditions were right ... wrong. I had a lot of trouble with tearing up the hay patch - was a mess.

Being a newbie, I had to look up a scarifier. Best I can tell that is called a "ripper" ? It looks similar to my renovator without the coulters ? Would a ripper tear thing up too much ?

I wondered if just running coulters might work ? Anyone know ?

I have a coil-spring protected Dirt Dog (brand) All Purpose Plow. It is pretty much your concept. The APP, while robust enough to pull through Bahia Pasture Grass growing in sandy-loam soil in Florida, may be too delicate for clay in Texas.
I only pull it through Bahia pasture when the soil moisture is ample but I go at least 10" deep.

Ideally, I would want to work 7.5 acres (my hay field). IF I find something acceptable, I would also use in the pastures in places. One issue I had was when the soil "looked right" to renovate, the top was okay, but the deeper clay was gummy and got pulled up on top in chunks. That's why I was wondering if instead of the "foot" on the bottom of the shank maybe a straight bar could be used ?

Again thanks to all. I have some good ideas. Jeff9366 : I have a friend nearby that has a coil spring plow. Will not work very well around here unless you disc first. The soil is .... good soil to make bricks... have considered building a pyramid. The subsoiler is a possibility although I think I would have the same issues as with the renovator, and of course, this is a single row.

My dumb idea was something like a renovator, but instead of the renovator shanks, a straight bar with angled (sharp) front... ? Guess there is no such thing.
