    Default HP per foot of field cultivator?

    Looking at buying something like this. John deere - 1100 9' Field Cultivator - Cultivators - Acreage Equipment - Catalog - Ludens Inc.

    Have not used any tillage equipment in about ten years and I have forgot the rules of thumb. I know I pulled a 7' cultivator with a 4WD 47 hp tractor. Wondering if my current 95 HP 2WD tractor could handle a 15' cultivator?

    I know if you take the sweeps off and try to run the chisels deep it takes a ton of HP but I don't really remember the plow having a lot of drag with the sweeps on but it has been a long time.

    According to http://archive.lib.msu.edu/DMC/Ag.%2.../PDF/e1152.pdf, 3.5 HP (drawbar) per foot.

    So much depends on the weight of the tractor and soil conditions. We pulled an 18 1/2 foot fully mounted with 85 HP white and our 5000 Ford that was after market turboed. Neighbor pulled 15 1/2 foot pull type with 4240 JD in similar soil conditions. Typically running depth around 6" on plowed ground. All of them 2WD with duals.

    I don't cover a lot of acres agriculturally. But I have a pulltype 15' that I use on my M9540. It handles it easily, especially at normal tillage depth. I think a 3pt style would be even easier to handle because of the traction you could gain. My pull type is dead weight and does nothing to add traction.

    Thanks for that link, Steve. Very good information and cleared up a question or two that I didn't even know that I needed to ask.

    Thanks for the replies. My tractor is heavy. It has a cab, a loader, and the rear tires are loaded. I can't remember the exact weight as it was several years ago when I filled them up but if I recall it was around 800 lbs of liquid per tire that was added.

    Yeah, I believe you outweigh me by 1500lbs or so. I have 675lbs of fluid per tire, plus cast centers, plus 140lb wheel weight per side.
