The STIHL KM 91 R helps simplify professional landscape maintenance by putting a wide range of tasks within reach of a single powerhead. As part of the STIHL KombiSystem, it pairs with a variety of attachments, allowing you to move from trimming and edging to pruning, blowing, and cultivating without loading extra equipment onto the trailer. It's a practical way to save space, reduce clutter, and stay productive throughout the day, especially when the work ahead calls for more versatility than a single-purpose tool can provide.
Powered by a high-torque STIHL 4-MIX® engine, the KM 91 R delivers the performance needed for demanding work. An expanded fuel tank and 30% longer run time compared to previous models help keep interruptions to a minimum, while the quick-release coupling makes attachment changes fast and tool-free. The loop handle provides excellent maneuverability in tighter spaces, and features like One-Touch Stop, a semi-automatic choke lever, and the STIHL anti-vibration system help make long workdays more comfortable and efficient.
