The Hyundai HYM120LI510 is a cordless, self-propelled lawn mower powered by a 60V lithium-ion battery system. This mower is designed for medium to large-sized lawns, offering a convenient and eco-friendly alternative to gas-powered models. Let’s delve into the details to see if this mower is the right fit for your needs.


  • Cordless Convenience: Free from the hassle of cords and extension leads, the HYM120LI510 offers greater maneuverability around your lawn. No more accidental cord snags or limitations on where you can mow.
  • Self-Propelled Drive: This mower features a self-propelled drive system, taking the strain off mowing larger areas. Simply guide the mower, and it propels itself forward at your desired pace.
  • Large Cutting Width: With a cutting width of 51cm (21 inches), the HYM120LI510 efficiently tackles medium to large lawns, reducing mowing time significantly.
  • Long Runtime and Fast Charging: The dual 58V batteries provide a runtime of up to 60 minutes on a single charge, suitable for most lawns. Additionally, the fast charging time of 45 minutes per battery minimizes downtime between mowing sessions.

  • 3-in-1 Functionality: This mower offers 3-in-1 functionality – collecting grass clippings in the 65L grass catcher, mulching grass clippings for natural fertilization, or rear discharge for taller grass.

  • Safety Features: For safety, the mower features operator presence control, a safety key, and a lock-out button to prevent accidental starting.

Overall :

The Hyundai HYM120LI510 is a powerful and feature-rich cordless lawn mower ideal for medium to large lawns. The self-propelled drive, long runtime with fast charging, and 3-in-1 functionality make it a convenient and efficient option. However, the weight and potential limited availability are factors to consider. If you prioritize maneuverability or find a more budget-friendly option, alternative cordless mowers might be a better choice. If you have a large lawn and value features like self-propulsion and long runtime, the HYM120LI510 is definitely worth considering, especially if you can find it in stock.
