I am looking around for a used offset pull disc for a 30 hp 4wd tractor. Is a 6 footer too big? I found 5 footer for $600.
A friend got a 6 footer for $200

If I remember correctly you need about 9hp poer foot. Not sure they build a 3 footer. /forums/images/graemlins/laugh.gif

What is an offset pull disc? Does anyone have pictures? Thanks /forums/images/graemlins/confused.gif

No pic, but it's a heavy, agressive, primary tillage tool. Usually a transport type disc with wheels on cylinders and gangs arranged in the shape of half an "X" (or like this>).

This is a used 6 ft "Case" offset wheel disc that maybe will show the basic concept. --Ken Sweet

find a picture either of your own or something from tbn pages or internet of this offset pull disc and attach or link to it so people aren't confused about what you are talking about.

I am sure you mean a double offset disc made of angle iron frame and 16 or 20 inch disc whose axles in the form of an "x". I am sure your tractor can pull this described disc.

Milkman has it right and sweettractors has the picture. don't know if that is what you really want. Also I am not sure one was made for that small of a tractor. The double offset tandem disk is the most common. I have one for my 18.5 horse Satoh. The gangs are more of an x shape.

Hello Troweller,
Welcome to TBN.
The offest disk is typically configured like this --\:/
(the colon is the wheels) /forums/images/graemlins/wink.gif. However, I guess you could assemble one in reverse and make it a right-hand disk. /forums/images/graemlins/confused.gif You may be able tho find one older model that you'll be able to pull with 30HP. The trend in today's disks seem to be ever larger discs [the circular blade] and larger disks [the implement], and heavier frames for better penetration. They are a great tool for tillage, you always need to turn left or it can climb the tire. We used to use it to disk under the citrus trees. They can be adjusted to follow way to the right of the tractor so they can run under the trees a couple of feet.
For more information, do a google search for offset disk.
I would pick up the disk for $600; sounds like a deal. You could always resell it if you decide you made a mistake. Make sure the bearings are good.

Here is a link for some small disks:

Hello oliver28472,
I used to see 4' to 6' disks being pulled by a Ford 8N with no trouble other than some wheel slip. As I said in my previous post, you just need to shop around to find an <font color="blue">older</font> disk. They're out there if you can find them.

Milkman, No, that's correct. Just depends on which view you intend to represent. I like the drawbar, good character. /forums/images/graemlins/laugh.gif

Troweller, I'd see if I could pull it first. Offsets aren't that easy to get rid of. They go unsold at auction a lot. An 8' went for $390 at last one I attended. Lots of no till these days. Not that many orchards use them anymore since the switch to herbicide weed control under trees.

Funny thing, down here in <font color="red">TEXAS</font> there is a good market for them.
As for herbicides under the trees, I (and most people given the choice) don't particularly care for Roundup or Krovar residue in their fruit! /forums/images/graemlins/crazy.gif

Not sure about oranges but discing soil destroys feeders which are mostly in top 6" of soil. This stunts tree growth and harms vitality of most fruit trees. One experiment found just mowing was better than discing inside drip line.
Glycophosphate is rendered inactive upon soil contact. Not sure how it would uptake into fruit. Majority of fruit growers are using this method, except maybe the organic guys.

Hello MMM,
Yes, I know that there is <font color="green">some root pruning</font> when you cultivate inside the drip zone, but this has been shown to stimulate growth (unless you go nuts and cultivate too deeply.) in citrus trees. The main thing to keep in mind is not too often. Tolerate ankle to knee high weed growth as that is a good indication of soil moisture and nutrients.

There have been studies that demostrate to both conclusions that chemical residue ends up in fruit (personally, I beleive that who ever funds the study, can make it say what they want). While I don't go organic completely (I do fertilize twice a year with ammonium sulfate [21-0-0]) I don't use anything else on the fruit. If you like the way the crap from the grocery store tastes, well you are getting the full load of the commercially grown flavor that the pesticides leave. Once in the store, the stores themselves continue to dose the fruit with chemicals to lengthen the shelf life and for cosmetics. If you enjoy the herbicide grown type of fruit, enjoy.
For me, I'll pass and I'll continue to cultivate my fruit thank you.

Apples and oranges. I grow Mayhaws (Crataegus aestivalis), wich are kin to apples. Could be a big difference in feeder depths. I didn't know any fruit tree had a taste for straight N. I am a commercial grower for jelly and wine industry and consume my own jelly, but haven't noticed any taste difference between wild and cultivated fruit. I think most of the grocery store taste is from premature harvesting and cultivars that favor shelf life and bruise resistance over flavor. Good luck with upcoming harvest. (I think oranges ripen soon?)

-Thanks for the input on discing.
-I like the offset drag discs because I can turn with them
-I have been using a 6 foot offset drag disc to prepare a garden for winter cover cropping and my tractor,Kubota 3010 4wd, can pull in a low gear and 4wd @2000 rpm.
-I realize that I am working the tractor pretty hard, but field work is not easy on equipment.
-I wonder if I will run into problems in the spring after I plow and try to pull the offset disc across the plow ruts.
-I found some more discs for sale 5.5' for $200
