David Bradley? Disc harrow identification

[oldcarzrule]

Pulled this old disc harrow out of the woods this weekend. I was looking into fixing it to put back into use as I can’t afford a new 5ft disc harrow. All I know about it is when we bought the property in 2009 it was here and most likely well before that. It has a tag that says it’s a David Bradley disc from Sears & Roebuck but I think it’s been converted to a three point hitch by the previous owner. The model number is 917 5811. But it doesn’t have a serial number. Any information on it is helpful.

It is what it is at this point. Nothing left to adjust its welded up the way it is.

Grease the heck out of, see if the axles turn, grease it again, hook it up, adjust the top link so it is level when in the dirt, and go.

When the blades fill up with wet clay dirt (Im very familiar with this, we try to use field cultivators here in our wet clay now) those levers can have ropes up to your seat and you can wiggle the mud cleaners to help clean off the blades. I wouldn’t bother it’s an exercise in futility, but it is nice to be able to move the scrapers while trying to knock the dirt out.

You can put cinder blocks or rocks in those trays on top to be,o dig into harder dirt. Depends what your tractor can lift, and how much wear you want to put on the disk.

Then grease it again. Often. In general these age disks do not have bearings as we know them today, they have wood blocks or cast soft metal as their ‘bearings’ and depend upon a layer of fresh grease to turn on.
