chisel plow ?

[beanman]

I have a 9 shank int. 5500 chisel plow,no disks, about 10 ft. I have been using it on the bean ground with my j.d. 6400, works good. I have been moldboard plowing the corn ground though because I plant with a j.d. 7000 conventional planter. was thinking of getting a disk chisel,like a j.d. 714,thinking it would bury the stalks better and maybe getting away from moldbd. plowing all together. would a 10 ft, disk chisel pull any harder than my 10 ft. regular chisel? thanks for any info.

I wouldn't think it would pull any harder because it just has straight coulters not concave discs. Have you tried your current chisel plow on the corn ground? The only thing the coulters will do is cut the thrash in smaller pieces.

I wonder if it wouldn't be easier to work on the corn planter so it would handle some trash? There are a ton of aftermarket accessories for a 7000, and I think you could easily make it plant through trash. I'd be surprised if your tractor could pull a 9 shank disc chisel. Here, I think you would 125-150 hp to pull that.

Most coulter chisels have more aggressive points than chisel plows and generally would pull harder for the same number of shanks. Your 85hp tractor would maybe pull 7 shanks but I would doubt that it would handle 9 shanks very well unless you have light soil. If I remember the Deere literature correctly it said a minimum of 60hp for their smallest 5 shank model of coulter chisel.

you can get diff. ponits that throw more dirt i think there twisted

"here" my 1066 IH pulls an 11 shank chisel.. I hooked it to an IH disk chisel of the same width, 9 shanks I believe, and it fell on its face. I'd try one before I paid for it.

It would have to pull harder, even if the discs are straight cutting blades. You"re doing more work, and dragging more pounds of implement around the field. Most disc chisels don"t work well unless the stalks are chopped, either by the corn head, or a stalk chopper. I have a White 435 12 shank disc chisel, remember when they came out....fields looked like crap with all the long stalks on top....farmers went back to chopping stalks before using the disc chisel. Stalks rot better/faster....don"t tie up as much N while decomposing.

Your JD 6400 will not pull a 9 shank disk chisel plow very well. They do pull harder. The reason it the disk angle. A coulter chisel with straight disk would pull a little easier than a disk chisel but I still think you will have problems.

What would work better would be to just get a stalk shredder. Shred the cornstalks and then just use the chisel you already have. The stalks will be shorter this way. A disk or coulter chisel still leave some longer stalks on the surface. With them shredded you will not have that issue.

I always chop the stalks and the combine has a chopper also. I was concerned also about switching to soybeans after corn and planting with my 452 drill. I always disk and go over with a field cultivator before palnting.

Not familuar with your chisel but when I had mine the shank spacing was 12" and the disk chisels at that time were 15" shank spacing so each shank covered a wider area and in doing so to get the ground broke up instead of running 8" deep you had to go to 10" deep to get the biddle between the shanks broke up and the plain chisel had 3" twisted shovela and what was being sold for the wider spacing disk chisels were 4" twisted shovels so just figuring a 9 shank would be 9' and a 9 shank disk chisel would be 11'4" so natrually it should pull harder, a 7 shank would be closer in width to what you have as far as width and would pull twice as hard as what you have now figuring the disk blades plus the extra depth that you have to run.

I had a 6500 caseIH chiesel plow 9 shank and pulled it my 1486 with no problem but the new corn with the stronger stalks it could not handle them, I changed to a bigger a tractor and bought a Landoll 2200 disc chisel and like it better since it cuts the stalks much better and burys them.
