Hi Keith,
     It was good to speak with you last night. I have searched through various manuals that I have, but there is no reference to the plow pulling hard sideways as you describe. 
  One thing I found, .......    If plow runs crooked- possible cause....disc jointers out of adjustment. ....cure- a. the disc colter arm should be parallel with the plow beams. (the colter blade should lead into the land and not toward the plowed ground)  b. run 2" to 3" deep.
 I would be really curious to know what turning the crossbar of the plow end for end would do .
       I will ask some of the old timers around here who may know when I get the chance.
          all for now,
                 Cal Innes
