    E Series™ Engines

    Reliable performance. Exceptional value.

    Ideal for smaller acreage lawns, our E Series riding mower engines are powerful, yet lightweight. Their performance-enhancing features deliver more than you’d expect, at a great value.

    • Advanced Debris Management – Helps our engines run cleaner and longer by deflecting and ejecting grass and debris, providing a longer life.
    • Anti-Vibration System® (AVS®) – Counterbalanced internal components give you a smoother ride and save wear and tear on your engine, your equipment – and you.
    • Splash Lubrication System – As the engine is running, a spinning gear with paddles slings oil on critical components for vital lubrication and reduced wear.
    • Made in the USA of US and global parts.
