There are shims. When you fit the discs you fit or remove shims until the discs are just touching.There are spacers behind the discs, from memory. An owner of one would be better placed to comment. @Badshot ?
The problem comes when the discs cut through a raised ridge of soil. The soil enters between the discs at the top of the opening and as the discs rotate and get closer together the soil gets nipped which stalls the discs.
