This shaft guard encloses the rotating driveline between the tractor PTO and the baler’s gearbox input. It is positioned within the bale forming system, where it prevents entanglement with the spinning shaft and protects the universal joints from debris impact. A cracked or missing guard exposes the driveline to contamination and creates a safety hazard for operators. The guard is formed to match the original assembly’s profile, ensuring it clears the adjacent frame members and does not interfere with the shaft’s articulation angle during turns. On reinstall, verify that the retaining clips seat fully and that the guard rotates freely without contacting the shaft.
