JD disc plow

Can anyone tell me about this plow? Model? Vintage? Value? How hard do they pull? Would my JD 50 pull it? Thank you. It is for sale near me.

Oops. Forgot pic.

Your JD 50 will not pull that. Need more like a JD 70 or equivalent.

It looks similar to the one we had which was a 5 disc 100 series. Yours looks like a later 600 series. Vintage wise it would be correct for your 50 but it would pull it as long as you keep it out of the ground. That size of disc plow was normally handled by a JD D. I have original JD Better Farming magazines and one has a picture of a 50 pulling a 2 bottom disc plow.

Thank you for the quick replies. I won't run out and buy it. I never have been around disc plows so didn't know how hard they pulled.

I recently bought a very old plow that looks a lot like that except the front wheels are missing and maybe what seems to be disc scrapers
for scraping the goey dirt off the discs. It's a 3 pt.....which doesn't need front end support.

I never ran one before and I got out and tried to understand it. Seems like it's made to cut a swath about 4' wide. With the discs being
about 3' wide, that would amount to about ⅓ of the discs in the dirt. It's not adjustable laterally. The angle is a welded frame including the
3 pt connections. Unlike a drag type. It sticks a long way out behind the tractor. I'm pulling it with a 65 hp Branson 4wd and I load the FEL
bucket with gravel to help keep the rear up in the air for transporting.

Filling in the blanks on how to use would be greatly appreciated.....Wink!

When I first moved out here in '79 the one like yours was quite popular. They were called "One Way Breaking plows", used in black clay
rather than moldboards as they didn't gum up. This one I bought is the first one I have seen around here for sale and if I can figure out how
to work it properly. I like the 3 pt option as it's just handier for me. On the subject subject of transporting, I don't know how the farmers
back then got them from one field to another.

We used these quite a lot in West Texas where I grew up. Pulled a 4-disk with a 1950 A in second gear, sandy loam soil. The G did better and would pull it handily in third. Never saw a moldboard in that area in those days (50's and 60's).

Disc plows lift out of the ground just like moldboard plows to move from one field to another.

Not sure what you mean by saying "that would amount to about 1/3 of the discs in the dirt". Can you explain that some more? Thanks.

I think that is a 904, I have a 3 disc and can barely make out 903 decal on it. Have 4 disc for parts. Think quit production in late 40s. They call that a turning plow out here in west central tx. There used to be a lot of oneways out here . They have more disc closer together and can only turn oneway. Neighbor has 2 big Krause's as yard ornaments. There 10 or more disc on them.

I think you have located a model 404 mechanical lift plow. Back in my youth I drove a JD 530 pulling a similar model 404 plowing many acres. What are the owners asking for the plow? Those seem to be getting more connectable. JD built several different models including 90,100,200,300,400,500 & 600

If you'll post or email me a photo of your 3 pt disk plow I will try to
advise you on how to adjust it so it will plow. I own a JD F225 3 disk 3 pt plow.

They're asking 500. They also have a moldboard for same price. I probably won't buy it.

"Disc plows lift out of the ground just like moldboard plows to move from one field to another."

Assume that's the purpose of the crank and also to set the depth when plowing. I assume it rolls over dirt or gravel roads, not hard surfaces with metal wheels???

"Not sure what you mean by saying "that would amount to about 1/3 of the discs in the dirt". Can you explain that some more?"

Imagine if you had a pool of water behind the tractor and let the implement down till the bottom ⅓ of the disc's diameter was submerged. That would be the depth of the gouge made in the soil by the implement vs untouched soil, is the question. Like a 16 moldboard might make a 5 ?" deep gouge for an assumed reference.....just trying to see if I'm getting where I'm supposed to be with it. I realize that soil condition makes a whopping difference as does whether or not you are making multiple passes to get to the desired depth.
