摘要： A system and method for performing cutting operations with an agricultural implement includes a cutting member capable of cutting plant material supported on the agricultural implement. A vibration source is operatively coupled to the cutting member. The vibration source is configured to generate a vibrational output at an ultrasonic frequency which is transmitted to the cutting member. The vibrational output is propagated through at least a portion of the cutting member to vibrate the cutting member as the plant material is being severed during the performance of the cutting operation.
