can you move the plough sideways on the crossshaft ? on many old ploughs the lower tractor lift links connect to either end of the cross shaft , which is essentially joined to the plough frame by u bolts..... slacken the bolts and move the shaft accross the plough frame. the shaft should also rotate to lean the plough over a bit for ploghing the first furrow or two where the tractor is running level on the surface , rather than tilted with one side in the furrow bottom.
