The concept of torque isn't new. It has been a measurement of power in such things as skiing, golf, and other activities that use or require a twisting turning motion.
It is the measurement of force needed to cause an object to rotate. And in outdoor power equipment, torque is the most direct way to determine an engine’s ability to get the job done. Torque is the work power generated by the engine that keeps the blade spinning on your mower, drives the pump on your pressure washer, and turns the alternator on your portable generator. More torque means improved performance. And the more torque you have, the better.
