It may be that the material put into the machine is light in weight, such as large soft leaves, and cannot reach a sufficient speed to be discharged through the discharge port. As a result, the material accumulates in the cutter box, and after repeated cutting, it becomes fine fragments and can no longer be discharged. If this happens, the machine should be shut down as soon as possible and the cutter box should be cleaned.
The wood chipper is used to chop fresh branches. The branch fragments are of sufficient mass to produce a good and continuous output flow. As long as the ratio of branches to leaves in the crushed material is balanced, the leaves can also be chopped.
