Chisel on 100 hp tractor

How big chisel will a 8010 allis or 7000 handle comfortably? Thinking buying a chisel but not sure what width or if tractor can handle one? What brands and models do you all prefer?

I had a 10ft-9shank on a 7000.   There is a lot to figuring out what/where.  that is where i would start; then you can adjust the amount of shacks to what u wanna do.   at the end, i had 2 shanks that ran between the rows and left the corn stubble standing.   mine had hydralic wheels to set the depth.  I went to a 3 shank ripper, that fit my needs much better then the chisel!

Better have 20 HP per tooth in my area with the red clay if you want to pull a chisel plow like it should be pulled.

Dad pulled a 12' 12 shank Brady, with a JD 4020 with duals, and M&W turbo. An 8010 or 7000 should be able to handle one as well.

For a 7000/8010 I would say a 5 shank would fit well. I pull a 7 shank Allis Chalmers 1500 min till with my 7020, but I'm not going very deep and I know it's making her work. Finally found a 7045 so I don't need to work the 7020 as hard.

I have a 9 shank I pull behind my 200. It is a pull type unit. It is a Bush Hog brand. I do not have any front weights and the front is very light. I don't have any problem pulling it but you sure know it is there.

I pulled a Bush Hog 12 shank chisel (12" on center & 3" twisted) with the 7050 and it was a breeze for it. Sunk it in all  the way. I thought the 9 shank 1500 was going to be a breeze too. Boy was I wrong!

I never had a disc chisel, any drawbar hooked equipment will need a heavier tractor and because there is no draft control may go deeper and need more power. I have used a 10 shank 3 bar,3 pt 3 inch twisted on a 7000 with duels but it would dino 128 pto . I now have a 2 bar 9 shank 3 pt with chisel points and it works well here on the 8010 or 210. If your in corn ground that is different.if mounted you'll need a 3 bar plow. I never worried a lot about the clay banks, not gonna produce anyway. Subsoil and move on. If I went to buy a disc chisel for the 8010 it would probably be a 5 shank, but don't see that in my future. Have you looked at offset disc, I use it more with a subsoiler than I do the chisel. Hope this helps

If you decide to proceed with a chisel plow I have a Mohawk 1100 with eleven shanks that is for sale. It's a 3 point model with gauge wheels. Needs points. 

Chisel are a tillage tool, less evasive than a moldboard and leave some residue on top for some erosion control. They are not for breaking up a hard pan. Normaly can pull a wider chisel than you can a moldboard plow thus cover more ground faster.

Thanks for the info guys !!
