Description
Overview:
This compression spring is a genuine Stihl component designed for the AutoCut series mowing heads. Made from durable steel, it maintains the correct tension within the head so the bump-feed mechanism and spool return work smoothly. It helps ensure consistent line advance and reliable resetting after each tap. As a Genuine Stihl part (MPN 0000 997 3102), it is a direct replacement for worn or lost springs in AutoCut 36-2 and 46-2 heads, and is also used in the 56-2. Suitable for both professional and domestic users, replacing a tired spring can quickly resolve issues such as erratic line feed, slow spool return, or a head that fails to engage properly, supporting efficient cutting and reduced downtime.
