Just picked up a very nice 2 bottom JD plow today. I was wondering what model it may be. On the main beams it has #583 on one and the other #623. It is a trip style ground lift plow with one high steel wheel on the left and a spoked rubber wheel (rubber needs replacing) on the right (is this correct?)..... plow shares/moldboards are excellent too.

I can say it was a very good day as I also picked up a JD #44 two bottom plow -says No.16 frame and No. 44. It may still have original paint and all plow share/moldboards are excellent and good tires as well.
The JD #44 looks newer, so I was wondering if it's any better?
Thanks for any info..... Along with the plows were two JD model H style 50 manure spreaders (one good and one parts) and a JD tandem disc of about 9-10ft.
Brought home a 6 ton hay rack running gear and a 3pt back blade too.

Was a good day to stop at a garage sale!!!

Others are correct on models of plows. As to which is "better"?? either one will do a perfect job of plowing if set correctly and tractor wheel spacing is also. Simple....if you want hyd lift and tractor has hyd then use the #44. If older tractor w/o hyd then you can't beat the ole # 4 B/C/D. See photo. This is 25 yr sod , '37 A and #4 B. First time out. Need to move tractor wheels in a little and align coulters better but am very happy with initial trial run. So you see , "better" has many meanings. Good score on all the implements though! A few more saved.

Plow would probably be a 4B or a variation of the 4B. Should be able to go to Deere's web site and print of a parts manual for most of the machines. If a drag type disk type in the letter K and it should come up unless it would be a ligjter weight disk and then the letter J to get the manuals. The 44 plow replaced the 4B in the lignup being newer and you have a large frame 44 that can be adjusted for either a 14" or 16" cut.
On the spreaders it is not style but series and the 50 would be the year they were made, most of what I hear are earlier series like 47 or 48.

I found that the plow is a 4C with one rubber wheel made from 1941-1949. Thanks much!

It"s not a 4C unless it has a big tailwheel.

Scott, Actually the 4D was the one with the big tail wheel. A 4C is a plow with a disc furrow wheel to keep trash from plugging the spokes and trash wires to push the trash under the furrow. Sometimes called a broom corn plow. The 4B, 4C, and 4D plows are all the same basic plow with different "work clothes". Leroy pretty well asnwered the original question.

I found on page 21 of a manual for this plow on the John Deere website, parts and picts of this plow with the rubber spoked furrow wheel. It shows being used 1941-1954 on 4B,4C, and 4D plows.
On page #22 it shows what could be the dish or drum style furrow wheel for the 4C plow.

Thanks again for all the help.

Yes, the D version had a big tailwheel too but so did the C. Look in your JD plow book.

Yes both the 4C and 4D had the big 19inch tail wheel. The 4C would not have had a spoke furrow wheel, and I doubt there was ever a No. 4 plow from the factory with a steel land wheel and rubber tired furrow wheel. Lots of modifications happen over the years. The point I was trying to make was that it is likely a 4B like Leroy said first, and any of the versions could be made from another (except the 4B was the only one built in a 12 inch size.)

You're right it is "series" not style on the manure spreader. I couldn't think what it said after getting to the computer. It looks like a series 47 or 48 as far as I can see, but some picts of a 48 doesn't have a tin shield over the drive chains -may be missing?
The disc measures 7ft across the front and has 15" disc' with the back being set to maybe 8ft wide. It has 14 disc front and back and needs about a dozen replaced to look real good. Would be useable as is I think, only a couple broken disc with nothing on the frame bent. It also has a lot of "K" part numbers but I'd think that the "J" disc may use many the same.
I plan to sell most of this and I'm not real sure what it's worth. I won't scrap any!!!

Thanks for your help.

A KBA disk with 7 blades per gang will have 14 per row or 28 total and the back gangs will cut an even 8' 8" and a 6 on a side is 7' 6" cut. the J series has a blade spacing of slightly less than a K series so the total cut width will be slightly less at abought an even 8' for a 7 blade disk. Either way if the blades only measure 15" in diameter then they are completely worn out. Both disks could be gotton with either 16" or 18" blades and the 18" will cut a lot better but they cost more and the thought was that at that time they pulled harder than a 16" that is the exact opposite of truth and so most bought the 16" blades and when they were used to running a old horse disk with blades wore to 13-14" or less those 16" blades looked like giant size.
