How big of disc can you pull with a 65-75 horsepower tractor?

Thanks for your advice.

TJH

You should be able to pull anything up to 14 ft. for a light finishing disk on dry ground and I would think you could cruise with almost any 12 ft. disk, they are usually light at that size. Years ago I pulled a 10 ft. Oliver disk with a 40 horse JD 60 and it saled with it, then my 1655 Oliver at 70 HP pulled the 10 ft. disk like it was not even there. Now I pull a 18 ft. Krause disk behind a 110 hp and it is all it can handle but there is no comparison in the weight and engeneering of the disk.

TJ,

I can't speak to the discing of plowed ground because I've never done that.

But, my little tractor is rated somewhere around 64 horse, and the 14 1/2' disc is a perfect match for my purposes. Pulls it all day long in 3rd gear and the disc does a very good job of slicing.

Hope this helps,

Allan

Hi Ol' Bud,

It is an IH 370, which is just the newer cousin of the 37. I liked the adjuster on the old 37s a little better; more iron to 'em.

First of all. What "kind/type" of disk are you talking about? Tandem Disk Harrow? Offset Disk? Disk breaking plow? Second thing is that within each category, you have to consider several things: Diameter of disks, Deep cone, deep dish, regular. Angle you have set the gangs at makes all the difference. Next how heavy is the piece of equipment; there are light duty tandem disks for finish harrowing; there are heavy dudy offset disks used for primary tillage. Get back to us with what you intend to do, and a little hint of what kind of equipment you are talking about.

I was thinking a Tandem Disk. I have not decided on a brand. I have some plowed ground that used to be hay fields and I want to disc it up to get rid of the clods.

Thanks,
TJH

For 65 PTO HP, you will be good with a 10 foot tandem. I have 67 PTO HP and use an 8 foot tandem; could easily pull 10 foot but like the convience of the 8 footer around the trees in some of my fields, through gates, etc. When only doing 10 acres at a time, the 8 foot is plenty. Tom

The size of disk you can pull greatly depends on a few factors. Those factors include: Soil type and condition, moisture content, compaction, depth, design of disks, incline of the ground, and tractor setup. Now that I've got your head spinning, I would say if you're disking into stubble on flat or semi-flat ground using a regular disk you could probably get away with a 14 ft. disk depending on setup. The next thing to take into consideration is how hard you want to work the tractor. If you dont want to work it as hard, go with a smaller disk. I have pulled an 18 ft. disk with a MM 602 LPG on some hills but it worked the tractor pretty good too. Another thing to consider would be if you're going to be able to get traction if you need to hit it again. A field that has already been worked will make things pull a lot harder than one that has been worked the previous fall or earlier in the year. Hope this helps.

Take a look at the John deere website under "Products and equipment" and go to "Tillage" and you can look up specs for discs. 65-95 HP should pull 8 to 12 feet of disc. I pull a tandem 8 foot disc with 22" notched disc blades on 9" spacing with a 9 foot springtooth drag behind that with a 62 HP MFWD tractor and do between 5 and 7 MPH. If I pull the 8' disc alone I have enough power to go too fast in loose soil conditions and throw dirt off to the sides with the front gangs that the rears can't reach to pull back. I could pull 12 feet of disc. MFWD makes a big difference.

I used to pull an old IH #37 four row tandem, angled all the way, with a 560 gasser, and when ya put two 55 gallon drums on the weight boxes and fill them with water, you can CHOP some cornstalks. Just plain the right combination there. But that was 30 years ago and everything has changed since then. Heck they say now the earth is round and stuff. What's up with that? Harley

Earth is round ??? I always figured it was flat. Folks that leave here are never seen again. I always thought they went too far & fell off the edge...

Here in S.C. it is flat. Just ask our state legislature.

Sounds like we should all become members of the "Flat Earth Society".
