The high-torque cutting capability of all RedMax edgers prevents stalling, which increases commercial operator productivity. A 22.5 cc, 1.2 horsepower engine powers the HE225F, allowing it to edge through the toughest soils. The curved shaft of the HE225F is fitted with a die-cast aluminum guard that is clog-resistant and more durable than competitive edger models with plastic guards. Finally, an in-line, vibration-dampening system is designed to reduce operator fatigue.
