older disc harrow, pull type, manual adjusting

[hkusamdoc]

I am just about to use an older disc harrow for the first time and need to know some basics. The harrow looks in excellent shape but hasn't been used for perhaps 20 years. It is about 6 feet wide overall with 4 gangs, 2 in each row. There are two adjustments. A long handle close to the hitch clicks into a number of slots and I guess this will adjust the offset. I want to have the discs running straight in order to move it down my driveway to the shop for greasing.

The other adjustment has a short handle with hole for a rope I guess. This looks like it might be a brake attached to a gearbox or enclosed chain which I guess will assist in changing the offset. Do I change while pulling or by backing up ?

I haven't found any name but the cast iron cover and case of the chain/gear have part numbers which start with letter H

Thanks for your help

Not sure yours is the same, but around 1950, dad had a drag type disk & if I remember correctly, you pulled the rope while moving forward to make it angle the disc to cut more dirt. You would drop in the slot to hold it when the desired angle was reached. I think backing up would straighten the disc angle.

Thanks Neal, That's also how I remember it from Virginia, also in the 50's when my grandfather pulled these with a JD Model A.

Ther is also writing on the chain lid "1 pt SAE 110 lubricant" There seems to be a drain at the bottom of the case and I will put in new lube and grease all the nipples and oil the adjustment parts.
