John Deere Disk Plow (Pict's)

Beatles65 · Jan 9, 2011

Considering buying this old John Deere disk plow. Was told it would be used behind a John Deere D.
The gentleman is asking $250 for it. About scrap price.
It looks really cool. I have never seen one before. It has weights on it. (Rear wheel)
What model number is it?
Would like to look it up at jdparts.com
What else can you tell me about it?
Thanks!
From Nebraska,
Andrew Kean

That is a oneway or disc tiller not a disc plow. looks to be of a size an early a could pull maybe even a late b. Depending on how deep. we used to pull 24' with 4430 and 12' with a 70. some of the 820-830's arond here pulled 16-20' models.Paul

You are correct that this is a one-way. The disc tiller is different, has smaller blades and lighter in weight so it doesn't cut as deep as a one way. Disc tillers made by John Deere were known as Surflex tillers and were made in (I think) 12-20 feet in cutting width. Surflex tillers (or similar machines from other companies) are likely what you are referring to as the machine in this picture with 6 blades is probably more than an "A" JD could handle, certainly more that a "B" could pull!! An uncle had an eight blade one way that he pulled with an LA Case. An LA Case is more powerful than an "A" JD. The blades on a one way are as big as the blades on a true disc plow and can cut as deep as a disc plow, hence one ways pull a lot harder than many people think.

It's a model 120.

I have an identical plow ACCEPT mine must be a newer model in that it is hydraulic cylinder lifted. We used it in rough (what we call new ground) after we have dozed and have roots left. In no way can I think a 2 wheel A john deer would pull it. I am thinking mine would load something like a John deer 70 . We uses a 85 hp 4 wheel drive and when it is in good gound it will be all the tractor wants. Will try and post photo as soon as the snow lets up. O I gave $ 800.00 for mine and thought I got a good buy several years ago.

thats the way to go if you can,especially with fuel prices going up and if you can pull it of course.I personally would stay away from that one though,unless you need parts.its not all there! and you could have trouble finding parts.at least one bottom is gone,which would lead me to think maybe bearings could be bad and someone started to fix it and then give up.I would check it very closely before i paid that much ,and know I could buy the parts needed.My opinion of course.I personally like disc plows and tillers,because you can often put a seed bed in condition to plant so much faster with less passes.

Yep, its a disc tiller, and the tail coulter is completely WTFO! You'll need to replace that, shouldn't be too hard of a job. If Its been sitting in the ground, might have rust issues with the other discs, and the bearings will need checking, too.

I'll say one thing the photo of that one-way you posted shows it is indeed an oldie.

Seems to be a terminology issue from location to location. On the great plains it would be a one-way. I've provided a link which should give an embedded photo of a disc plow.

This link will take you to a brochure for a one-way disc plow, said to be for Ford and Ferguson tractors.

By the 1970s not many farmers around where I lived used one-ways but instead used moisture conserving undercutters. Yet there were times when the one-way still served a good purpose and worked well. Some of the most fun I had farming was pulling 15' and 12' International one-ways coupled together with my Case 1070. I only did it on a couple of occasions but it sure worked well.

In the 1960s the Horchem family would hook two 15' one-ways together and pull them with Cockshutt tractors. Generally 2 tractors with implements in the same field so they covered a lot of territory in a days time.

why do you say "one bottom is gone". There are no bottoms - they are blades and they are all there. bottoms are on a moldboard plow.

55 50 Ron · Jan 10, 2011

If the 15' and 12' coupled together were indeed oneways, they couldn't have been cutting very deep if you pulled them with a Case 1070.

Same logic applies to the two 15' coupled together.

Tail coulter???? Disc plows, disc tillers and one ways don't have coulters.

frank whitehead · Jan 10, 2011

We called this a JD 6 disk tiller,they were very popular here in my area when cotton was grown.With good disk and adjusted correctly they do a beautiful job oj turning soil and building terraces. E mail open.Frank

All of these disc plows and tillers, have the tail coulter. It keeps them going straight. If you look at the first picture, and the second picture, too, you will see sandwiched between, in the first, weights, and in the second, a weight on 1 side, and a depth ring on the other. If the coulter is wore down to the depth of the first picture, the tiller will walk sideways, instead of plowing. The Ford British patent, in the second picture may have a little wear left in the tail coulter.

The best picture of the tail coulter, is the 3rd picture of the first set. Forgot how many pictures there were.

55 50 Ron · Jan 10, 2011

I'm not following your reasoning. There must be a difference in terminology between our understandings. Are you calling the wheels coulters? If so, I've never heard them called coulters. The only wheel that has weights in it is the tail wheel.

The only coulters I've known were on moldboard plows.

What part of the country or world are you in? Differences in terminology do exist I guess depending on where we live.

I'm interested to know if anyone else has called the wheels coulters.

The only terminology for the wheels I've ever heard for a JD disk tiller was frt or rear furrow wheel and land wheel never coulters.

I plowed a many a day back in my youth with a 8 disk tiller pulled by a Cyclone B. When the 8 disk,disk tiller is set for hard ground it will only cut about 4 ft swath.

skip33652 · Jan 11, 2011

maybe a little extra clarification A disc plow or a moldbord plow will bury residue and turn the ground black a one way or tiller will only bury small percentage of residue but will cut off weeds and lay them on their side. excellent for killing cheat grass. excellent in wheat country unless the ground got too dry and hard . typical working depth was 5-6 inches or less Paul

greenbeanman in Kansas · Jan 11, 2011

Probably about 3-4 inches max, possibly more like 2-3, I simply don't remember now.

Once the ground is opened the first time in the spring it remains fairly loose due to the low rainfall of the area which was about 19 inches a year at the time.

A lot of draft of a one-way depends on how big the weeds are you are working out, so the angle of the implement can be changed somewhat with hitch and wheel settings.

Speed isn't critical as long as the discs are doing a good job of throwing the soil. One-waying is one of the slower implement chores.

This is called a "medium disc tiller" model 260. It is in the JD parts section on line. If you want to look at one restored, I have one on the implement photo section.
