Honda GCV170 Engine
The heart of the Honda HRN Series is the all-new easy starting four-stroke Honda GCV170 engine, delivering nine percent more power and 18 percent more torque than the Honda GCV160 engine in the outgoing Honda HRR Series of lawn mowers. More power and torque relate directly to the ability of the machine to tackle tough mowing conditions while still producing the clean, even cut prized by people who are passionate about their lawns. More torque means more force is being delivered to the blades, which results in easier and faster cutting – especially in heavy, thick grass where stalling can occur. The power and torque of the new Honda GCV170 engine provide more stable RPMs for greater consistency in cutting, mulching and bagging. Increased displacement in the new GCV170 engine also contributes to more power and torque as compared to the GCV160 engine in the HRR Series.
