• Mowing Speed: These blades allow for faster mowing speeds compared to traditional mulching blades while maintaining excellent cut quality.
• Bagging Performance: While primarily designed for mulching, the Gator G3 blades also provide excellent bagging performance when needed.
• Sandy/Abrasive Conditions: The lower lift design of these blades makes them a suitable choice for use in sandy or abrasive conditions, reducing wear.
• Avoid Wet Grass: For best mulching results, mow when the grass is dry. Wet grass can clump and reduce mulching efficiency.
