2026 Stihl RM 655 YS

This powerful, low-maintenance mower features a mono-comfort handlebar, blade brake clutch, and hydrostatic gearbox.

The STIHL RM 655 YS is designed for homeowners who want to maintain larger lawns at their own pace without sacrificing productivity. Its hydrostatic gearbox provides infinite speed adjustment, allowing you to smoothly match ground speed to changing terrain, grass conditions, and personal preference. The result is a more controlled mowing experience that helps reduce fatigue while keeping work moving efficiently.

A blade brake clutch adds another layer of convenience by allowing the blade to stop while the engine continues running. Whether you're emptying the grass bag, crossing a driveway, or pausing to clear an obstacle, you can get back to mowing without restarting the mower. The mono-comfort handlebar provides easy access to the polymer grass bag and folds for convenient storage and maintenance, while the height-adjustable design contributes to comfortable operation throughout the job.

Built to adapt to changing lawn conditions, the RM 655 YS features a multi-blade system that handles cutting and mulching without requiring a blade change. Seven cutting-height positions make it easy to fine-tune your cut, while the polymer grass bag helps minimize dust with directional air vents and includes a fill-level indicator for added convenience.
