My recollection is the only adjustment is a fore/aft pitch adjustment via a handle & screw at the rear of the tongue that fits into the snap-coupler bell.

Here is a picture of my snap-coupler #109 disc with the beaming screw. I believe a #20 disc is similar in structure but doesn't have the beaming screw. It only has the adjustment at the back of the tongue (if I recall correctly).

rear gangs are adjustable for cut angle also.rear outer corner bolts are loosened and remove the other three on each gang to move adjustment.three positions according to the owners manual.front gangs are fixed,no adjustment.this is if you have a 20 series model.40 series have adjustments for front and rear gangs along with beaming adjustment.

I've always been of the believe that old farm implements, disks, plows, cultivators, etc. are probably adjusted to their optimal performance by the last user before they were abandoned, and should not be adjusted.

Some heat from an acetylene torch can do wonders for rust. Get it apart, clean the rust out of both parts and then apply some never-seize.

Had the same situation with mine. Prior owner pulled it with a D14, I'm using WD/WD 45's. First season back gang fine, front not doing much. Soaked it with ATF/PB blaster for a few months, put 5 ft pipe on handle--take it off or break it off point--,then got lucky and it moved. Now just fine.
