A tilling rotary shaft is a crucial component of rotary tillers, which are agricultural implements used to prepare soil for planting by breaking it up and mixing in organic matter. The rotary shaft is typically powered by the tractor’s Power Take-Off (PTO) system, allowing it to rotate and drive the attached tines or blades that perform the tilling action. The rotary shaft transmits power from the tractor’s engine through the PTO. This mechanism allows for efficient energy transfer, enabling the tiller to operate effectively at various speeds and depths.
