drag type disk

I have an old disk that came with our place. We use it to disk the garden once or twice a year and that"s it.

I"m not sure of the brand, but there are no wheels and it rides on the cutters when straight and then you back up to "V" the front and back row.

Anyhow, the inside wheels on the front wheels look like they have rubbed for years. Not sure how to adjust. Looks like some springs are present in front and not in back.

Not sure about the parts and how to service. Probably just a bunch of bearings. The whole thing squeaks alot but will last forever.

Please provide any insight or where I may learn about the tool. thanks, MODAY
 
On most of these old drag disks there were heavy cast iron "bumpers" on the inner ends of the front gangs that were designed to rub together when the gangs were angled. This prevented the bearings from having to absorb all the sideways thrust.

The bearings in your disk are probably just cast iron spools running in cast housings with no seals. abundant use of the grease gun on a regular basis will keep the squeaking at bay, or at least lessened.
 

Some old tandem disks used wooden brg halves instead of the white-iron brgs. If you could post a photo of tandem disk someone might could give more accurate advice.
 
Well
#1 The (cutters) are called discs, or disc blades
#2 You have a tandem disc, pull type.
#3 It MAY have wood boxings, especially if its a JD. The Boxings are or take the place of housings for the lack of bearings./ IF they are still there, your lucky. IF not, all the grease in the world wont help as there will be too big a space for it to run out. They can be made, IF you have at least one for a template. Dads JD Wing disc had wood boxings, and he had to replace them around 1960. He didn't believe in using much if any grease.
 
Does it make sense that the front bumpers would bump on the first row but the second row is a foot apart. I need to figure out how to upload pictures. It works great on it's weight alone. Not easy to transport so I'm sure that is why it was left here. There are some springs on top joinging left to right in back but not the front. I need to replace a couple disks too. I've considered buying a 3 point disk but this works fine for what little use it gets. thanks in advance, moday
 
Here are two JD models. The first is a JBA but they don't have springs as you said yours did. The second is a later model KBA which does have the springs front and rear. May or may not be one of these but these are the only pics I have.

Most JD's did NOT have wood boxings, would have to be back to horse drawn to find a JD with the wood boxings.
 
Front row the blades are concave to the outside and so the bumpers, the second row the blades are concave to the inside to return the dirt to where it was before the front row threw it out so it is made to have that foot of space in between the back rows, if it didn't it would be pluging there.

I will work on pics when I get home one earlier evening. Too dark right now after turning clocks back. Thanks and pics to come. I'll also try to look all around for a brand.
 
Thanks for the photos, now I know that I have an old JBA. Believe it or not, I like to use the front half, set almost straight ahead to cut grooves in the pastures in early spring before I broadcast grass and clover seed. I know that is not the proper usage ...but it works. I get very high germination rates....and it is easy to hook up and go.
