A 21 Teeth Rotavator Yoke is a component used in a rotavator, which is a machine used in agriculture for tilling, planting, and preparing the soil for crops. The rotavator yoke is a part of the PTO (Power Take-Off) system of the rotavator, which transfers power from the tractor to the rotavator. The PTO driveline of the 21 Teeth Rotavator Yoke typically includes a driveline shaft, a universal joint (U-joint), and a splined shaft.
