Direct-Drive Motors are linked directly to the blade and transfer all of the motor’s power to the blade. Belt-Drive Motors have a belt that transfers power from the motor to the blade. In belt drive systems, the motor can be offset away from sawdust generated during operation, causing the motor last longer. Belt drive systems require slightly more preventive maintenance than direct drive systems. So you'll need to check the belts for wear and proper tension periodically.
