How To Repair Chipper Shredder Blades That Do Not Cut

Blades
If the blades of the chipper shredder are engaged and spinning as they normally would but will not cut, the blades are likely dull and in need of sharpening. Though these blades are extremely strong and durable, they do wear over time and will require sharpening after using the machine for some time. Ensure you are not inserting material that is thicker or more dense than what your machine is rated for, and to not force too much material through the blades at one time. In certain circumstances, blades may be severely dented or damaged, in which case they should be replaced altogether. Refer to your user manual for specific instructions on how to care for and service the blades on your particular model.

Drive Belt or Idler Pulley
If the blades on your machine are not turning and will not cut, it is likely that there is an issue with the drive belt that is stopping it from rotating the driveshaft and blade assembly. The drive belt attaches to the flywheel at one end and the driveshaft at the other, powering the blade assembly. If the belt becomes loose or breaks, it will no longer turn the blades. Remove the belt cover to inspect the assembly. If the belt is significantly worn or has broken, it will need to be replaced. If the belt is in good condition but is not taut, the belt has become loose and a tension adjustment must be made before operating the machine.The drive tension of the drive belt is adjusted via the movement of the idler pulley. The idler pulley is the third pulley that the drive belt runs through. It is usually slightly offset and placed between the flywheel and driveshaft, with the drive belt running through it. The idler keeps the belt from slipping and also moves back and forth slightly to allow the user to increase or decrease the tension of the drive belt. Refer to your user manual for specific instructions on how to make this type of adjustment for your particular model.
