Powerful HD775 OHV SC Engine
The RM 655 is powered by a Series HD775 OHV SC engine with 10.6 in³ displacement and 2.6 kW / 3.5 hp rated power.
This power output is well suited for maintaining larger lawns and handling demanding mowing conditions while maintaining consistent cutting performance.
20.9-Inch Cutting Width
The mower’s 20.9-inch cutting width allows you to cover more lawn with every pass. This can reduce the number of passes required and improve mowing efficiency on larger properties.
The centralized cutting-height adjustment provides 7 height positions, with a cutting range from 1.0 to 3.3 inches. This allows the operator to select an appropriate cutting height for different lawn conditions and preferences.
Large 18.5-Gallon Grass Catcher
The 18.5-gallon grass catcher provides substantial collection capacity and helps reduce the number of stops required to empty the catcher.
This is particularly useful when mowing larger lawns where frequent emptying would otherwise interrupt the mowing process.
Drive System
The RM 655 features a drive speed range of 2.6–4.6 km/h, providing controlled forward movement while mowing.
The drive system helps make the mower easier to operate over larger lawn areas compared with a conventional push mower.
Designed for Larger Lawns
With a listed maximum lawn area of approximately 0.62 acre, the RM 655 is designed for substantial residential and professional lawn-maintenance applications.
Its combination of:
-
3.5 hp rated engine power
-
20.9-inch cutting width
-
Variable drive speed
-
18.5-gallon grass catcher

7-level centralized cutting-height adjustment
makes it a practical choice for demanding mowing tasks.
