Stihl Metal Grass Blade Installation Kit - FS56 - FS70

Convert your loop-handle STIHL trimmer for heavy-duty clearing with the STIHL Metal Blade Installation Kit (4144 007 1016). This genuine OEM hardware kit is specifically designed for 4180 series units produced in 2014 and later that feature a loop handle configuration. It provides the essential, high-strength components required to safely transition from nylon line to professional metal grass blades and brush knives.

Operating a metal blade requires precision-engineered hardware to ensure the blade remains centered and locked under high torque. This kit includes the specialized thrust washer, rider plate, and collar nut necessary for a secure fit. By using genuine STIHL parts, you protect your trimmer’s gearbox from the increased vibration and stress associated with brush cutting, ensuring a longer life for your equipment and maximum safety for the operator.

Fitment Note: This kit is intended for loop-handle models only. Using metal blades on loop-handle units often requires the installation of a barrier bar(included) and a specific limit stop/deflector for compliance with safety standards. Always consult your instruction manual before operating with metal attachments.
