The STIHL 4180 640 0114 Gear Head is a genuine OEM gearbox assembly designed for STIHL professional brushcutters. The gear head transfers engine power from the drive shaft to the cutting attachment, allowing the trimmer line head or blade to rotate efficiently during operation.
Manufactured with hardened internal gears and a durable aluminium housing, this gear head is built to withstand demanding commercial use. Replacing a worn or damaged gearbox restores smooth cutting performance and ensures proper power transmission from the engine to the cutting attachment
