Product information & specifications
STIHL RM 655 VS Self-Propelled Petrol Lawn Mower — 53cm Cutting Width
UK homeowners with large gardens or estate-style lawns seeking premium petrol lawn mower performance will appreciate the STIHL RM 655 VS. A 53cm (21") cutting width, Vario self-propelled drive system and a powerful 173cc Kohler engine make it built to tackle expansive lawns up to approximately 2,500m².
It's in stock at Gustharts as an authorised STIHL dealer, with free UK delivery on this order.
Vario self-propelled drive lets you vary walking speed while the blade stays at optimum speed — useful for inclines and varied turf. The Kohler HD775 OHV SC 173cc engine gives reliable petrol power with easy starting and long service life. A 70-litre grass catcher with level indicator reduces stops for emptying, and central 7-step cutting height adjustment (25–85mm) adapts quickly to seasonal lawn height changes. Blade Brake Clutch (BBC) lets the blades stop without turning the engine off — useful for moving across driveways or clearing bags. An aluminium deck and mono-comfort handlebar round out a durable, easy-to-store build.

- Kohler HD775 OHV SC 173cc engine
- 70L grass catcher with level indicator
- Central 7-step cutting height adjustment, 25–85mm
