  • On the ready to use discs we mount the blades. The most important thing is to ensure that they rotate freely. For this, you need the discs that were previously used for the husker. Their diameter should be approx. 45 cm. For the axle you need an old iron pipe with a diameter of 30mm. It is also necessary to install bearings: one for the pulley, one for the pipe.
  • Then we attach the blades to the axle shaft. You will need to install the pulleys on the pipe by welding.
