A backwards disk chisel, (chisel disk?) to make food plots

[AntiqueIron]

Some pictures of the area would be helpful, ad well as the rocks. There's a difference between fist sized vs basket ball sided. Also, does the area hold water at that shale layer?

No pictures unfortunately. Rocks are mostly brick to cinder block size, figure 3x4x6 being a common size about 8 inches deep.

No water vein that I know of shallow at least.

Also forgot to mention my tractor is a gasser, she’s gonna get a zenith this spring and she’s in tune good except for the Holley carb needing fiddling every time the temperature changes 5 degrees. Woof.

I’ve definitely wanted a chisel/APP for some time now.

The 1100 dollar one I mentioned is the crop king sold by Agri Supply. Seems like an OK unit, but I dunno how rugged.

Looked around and I can find some pretty big chisel plows around but they’re 8-9 footers. Think my ol girl might not like that. But I suppose I can use the torch and make em a 7’ 3 pointer.

The horsepower needed to pull a chisel plow depends on the number of shanks and the type of soil. A general rule of thumb is that each shank of a chisel plow requires 12–15 horsepower

That’s true, my thought was if I only run 4” deep it’d be close to a box blade’s tines. Figure that’s a fair load on the tractor but I may very well be wrong.

I am all for a no-till or minimum till method but the ground has to be establish first, you can't do a no till or even minimum till in virgin ground. Any tines type attachment wont do much other then scratching the ground, there's a reason it hasn't been done. Bottom plow your area and disk it, then removed the rock and even then you will have a hard time plowing it with all these rocks.

Maybe I’ll look for an Oliver 3 bottom, paint it up, use it for this and whatever else and have a yard ornament when it’s all said and done

Is this your dream implement?

So, that APP is almost the same as what I got, although mine is an older Massey/Ford/deerborn/who knows. It does a good job, and actually is better heavy duty, as long as A, you going at a medium slow speed, and allow the springs to trip and reset; and B, you don't turn to sharp with then down. Replacement complete tine assemblies, with springs, rippers, and tips are like $111, so not cheap, but if you do need to replace 1, it's not the end of the world.

It should pull those rocks up towards the surface, for gathering, piling, ect.

How's the existing vegetation? Lot of tree roots, crop residual, briars,? The APP does a good job on roots upto about 1.5", but when you get much bigger than that, it's not the tool for the job. It's not going to turn virgin soil to crop land in a single pass either, you will likely need 2 passes E to W and then 2 passes N to S (or at angles).

So, it will absolutely gather roots, and vegetation, that you may need to pull out and burn, and as pointed out, it doesn't chop like a disc (although IMO a disc doesn't chop veg as well as some think).

 

[paulsharvey]

Not to hog your thread, but, the reason I asked about water is, a true chisel plow is often meant primarily to break hardpan formed by discing, to allow water to move through the soil, and also allow the roots to penetrant that hardpan.

I've seen his inpliment before, but, what does the disc on the front do? It almost looks like when set straight, it almost is a gauge wheel?

 

[airbiscuit]

It pierces the sod in advance of the chisels. Makes for smaller clumps. I always wondered if it would make more sense to have the chisels in front and angled disc gangs in back.

What is APP?

What is APP?

All Purpose Plow, Bushhog and maybe another Lienbach? call it APP

 

[paulsharvey]

I haven't used mine in sod, just sand pasture that I think original owners goats ate the top layer of sand... but it did work well on pulling roots, and breaking the soil up. I could see the disc working in a heavy existing sod.

 

[paulsharvey]

In my thread on mine, trying to ID it and parts availability, it was mentioned that some of the newer, lighter, ones use a narrower tine, and either don't have replaceable tips, or use a non standard through bolt. I'd have to go back, but I think mine are just under 3/4" tines, but some are only 1/2?

"7 tooth spring ripper-cultivator-chisel" was the thread title

This is exactly what I was wondering about building. Figure some wide spaced serrated discs and it could in theory mulch sod pretty good.

Don’t quote me on this, but I think we have a cultivator at work that’s Disc-chisel-disc. Been a minute, I’ll look closer next time I go past it.

Straight discs in front of shanks is to cut grass, weeds, corn stalks etc. so they are less likely to wrap around and plug the shanks.

Angled discs are for stirring or turning the soil. Disc rippers like Case IH 870 or 875, Deere 3720, Kuhn, Dominator, etc. typically have angled blades in front and behind the ripper shanks to cut or size trash and help bury trash. These implements are heavy, our 18 ft is around 20,000 lbs. I think smallest size is 12 or 14 ft so not something you will pull with 5000 Ford.

Depending on tire type, soil type, tractor weight you may struggle with 7 ft chisel at 5 - 6” depth.
Huge difference in tilling light loam vs heavy clay.

Great insights. We also have a dominator set up that way at work, boy it just shreds stubble.

My tractor has 18.4-30 R1s that are basically new. Loaded rears, and with the loader she comes out around 9-10k gross. Not a light gal thats for certain.
