Abstract: A power take-off is provided to reduce rattling noise from the PTO driveline during idling and to present a mathematical model of the PTO driveline for designing an optimized torsional damper. A power take-off driveline to reduce rattling noise during idling of a tractor includes a flywheel(121a) which is rotated by being coupled to the crankshaft of an engine, a hub plate which is located at the side of the flywheel opposite to the engine side and rotated around a same axis of a flywheel, a spline hub which is inserted to the center of inner peripheral surface of the hub plate and rotated around a same axis of the hub plate, plural free damper springs which are placed in between outer periphery of the spline hub and inner periphery of the hub plate, a PTO drive shaft(131) which coupled to the splined hub, and a PTO transmission which is connected to the PTO drive shaft.
