CHISEL PLOW

[B GATLING]

Is ther a "rule of thumb" for the amount of horse power needed per shank of a chisel plow. Was always told 7 hp per ft for a disk but have never heard on a chisel plow.

Not sure. I just bought a 12 foot 13 shank International to pull with my 6788 that tested at 200 HP. I could have used a bigger chisel, I tried it just a little before this snow and the tractor didn't know the chisel was back there.I guess 15 hp per shank or 16.6 hp/foot is more than enough if that helps. I'd much rather have it that way than the reverse though.

Now I'm anxious for thisweather to clear up so I can chisel everything!

15 per shank/ foot is about right to start with. I have 10 shank on my 140 hp tractor, and am comfortable with that setup. Pulls easy some days; get into the compaction the chisel plow is meant to deal with & boy then you know it"s back there... So depends a little on the year and so on.

Granted, a chisel plow vs a disc chisel...12 foot chisel on a 4020 is fine, better on a 4240 or bigger. Just depends how fast you want to run, and how deep. 7 hp per foot on a field or finishing disc- don"t need that much. Chiseling is primary tillage. paul and Birdman are certainly in the range for current operations. Early days, with a Graham-Hoeme chisel plow, in the 50s-early 60s- hard to find a tractor that could pull a chisel wider than the tractor. HP simply was not there...but the idea of reduced tillage was fine.

That 7 HP per foot was for the early 3 point hitch chisel plows, not a disk. And that was pretty much what a 7 shank spaced on a 12" spacing took on a tractor like the Ford 5000 that was right at 70 HP on pto. That was running about 6" deep and they did not have the strength or clearance for deeper.

12-15 hp depending on soil conditions. You can always remove shanks if you need to. Ken Sweet

My 8000 ford pulls an 11 shank IH chisel plow no problem 5th gear.
