Description
Overview:
This genuine Husqvarna drive shaft is the internal power‐transmission shaft for selected straight‐shaft brushcutters and trimmers, including the 525RS and 525RX. Made from durable steel for strength and wear resistance, it sits inside the shaft tube and transfers torque from the engine/clutch to the gearbox and cutting head. Replacing a worn or twisted shaft restores smooth drive and cutting performance, helping prevent vibration and loss of power. The overall length is 152 cm (5 ft), matched to the specified machines for correct engagement at both ends. Designed to OEM standards, it provides a precise fit and reliable operation in regular landscaping, grounds maintenance, and site clearance work.
