The organic farmer down the road from us is wanting to get a field cultivator for his farm. He had ask me about how many HP he would need to pull it per foot.The soil is red clay.Nobody in my area has one so we don't know what to tell him.Will a 180 HP pull a 30"?
 
Don't know about red clay, but I have a 250 hp four wheeler on 30 feet, A lot of times that isn't too much and I
don't have clay.

250 HP on 30' FC or you cultivating or plowing?

I've pulled a 3 pt 24' field cultivator with my 120 pto HP tractor with no problems.
 
Should work pretty good my cousin pulls 45 feet
with spring tine harrow with an 8300 John Deere
and 4 John Deere lz1010 hoe drills behind
 
Organic will be easier i pulled a 12 with a
1650 neighbor pulled 14 ft with a d 19 duals
will make a difference if the ground is soft
 
My FIL pulls a 30-footer with a 175 hp CaseIH 7230 (rear duals and front assist) and we have pretty
tight gumbo. In our area field cultivators are rarely run more than an inch or two deep and in
these conditions the 7230 has plenty of power for the 6.5 mph speed we run. Obviously the deeper
you sink it in the harder it will pull so if your neighbor has ideas about running at the maximum
depth the cultivator is capable of the power requirement would need to be figured accordingly.
 
150 horses will pull it but only 2"or 2.5" deep. Four or five inches is a whole different story but A field cultivator is not built heavy enough to withstand constant 5 inch depths anyway if it will even go that deep. At three inches deep 180 horses is OK, 200 will pull it in any conditions at three inches deep. I pulled my 30' 960 Deere field cultivator with 7" sweeps with a 165 HP 4650 Deere for a few years and it did OK at 3' deep at 5.5 MPH but it was using every pony. There was no extra power for the tough spots. Then I pulled it with a CIH 215 (215 HP) for a year. The 215 handled it at 6 MPH but I could tell it was working fairly hard to pull it. Now for the past two years I've rented a Deere 8430 running somewhat under 300 HP to pull it and it just breezed along at 6 MPH.
 
You guys are scaring me. We pull 24 foot with 1466 deep is about 3-5" in 4th low then second pass is just to smooth it out in 1st high I have pulled a 25 foot soil finisher with it. Not deep but so it would work fertilizer in a couple of inches.
This year one stieger on the soil finisher and one on the disk where needed. 1466 will be on the planter.
 
Why so shallow? That does nothing that I can see. Wanted 3-4" for normal. And I pulled a 13' Ford behind a Ford 4000 and pulled it with a late JD A as well but was a might much for the JD. That Ford is rated at 52 max pto hp but put out 60 on the dyno.
 
We run shallow for a couple of reasons. Here a field cultivator is used primarily for weed control and seedbed smoothing. For these jobs just shallow operation is all that is required and it uses less fuel than going deep. More importantly, shallow cultivating allows for seed placement into the firm, moist soil underneath the dry worked layer. With our fickle weather if you cultivate deep then place the seeds in the loose soil it could dry out before the seedlings got their roots down to the moisture.
 
I like your answer. Makes sense for your conditions. Most farmers are running much shallower than years ago.
 
Here if I tried that it would be just riding on top of the weeds and not tearing any out and then would not be loose enough for to get seed down to planting depth. What I have seen on a field cultivator the wings of the sweep at that depth would be on top of the ground.
 
I have an old ih45 21ft vibrashank. It's
all our 4430 or 4320 want the first trip
over chisel plowed ground. Second trip over
it gets run just deep enough to level/bury
fertilizer and has a packer behind it. They
play with it then. 4430 is @160hp with
20.8-38 duels. 4320 @150hp 18.4-34 duels.
