Re: Making an A axle steer easier
An improperly shimmed spindle bolt bearing will make one very hard to steer. Make sure the load of the spindle is actually being supported on the spindle bolt bearing, -and not the spindle rubbing on the axle beam boss.
Next, I would say the steering on the tractor was/is likely worn however the box should have many turns from lock-to-lock. Disconnect the Pittman arm to see whether the steering gearbox is turning stiffly or whether it is in the steering arms and tie-rod ends. I cannot see what you are using for tie-rod ends, but if they are stock Model-A type, they may be adjusted incorrectly with too much spring tension.
