Industrial GRA3-255 Grass Blade for Lawn Mower

Industrial GRA3-255 Grass Blade for Lawn Mower is a 255 mm (10 in) three-tooth grass-cutting blade designed for mowers that accept the GRA3 series. It has a 255 mm outer diameter and is available in bore variants of 20 mm (GRA3-255-20BA) or 25 mm (GRA3-255-25BA). The 20 mm version weighs 375 g. Made from Swedish steel, Windsor grass blades are rated for up to 13,000 RPM, suitable for high-speed mowing decks. The three-tooth configuration provides a wide cutting path, and some listings include a spacer to fit both 20 mm and 25 mm mounting holes, aiding cross-model compatibility. Ensure your mower’s spindle bore matches the selected variant and that the deck is designed for GRA3 blades before installation.
