RM-655-VS

STIHL RM 655 VS 21 in Self-Propelled Mower | Vario Drive | Blade Brake Clutch

The STIHL RM 655 VS is a premium semi-commercial 21-inch walk-behind mower designed for users who need high durability, strong cutting performance, and professional-level control features. It sits in STIHL’s upper RM 6-series lineup and is commonly used for large residential lawns and light commercial work.

It is powered by a Briggs & Stratton or Kohler 173cc–190cc class engine (varies by region/model batch), delivering stable torque and reliable performance for dense grass and extended mowing sessions.

The key highlight is its combination of Vario variable-speed drive and a Blade Brake Clutch (BBC) system, making it much more efficient for stop-and-go mowing compared to standard residential mowers.
