Center Hole Size. Oregon® Gator® G3T 95-605 is your go-to blade in all conditions including wet, dry, and sandy turf. It’s not a replacement blade. It’s an upgrade. Requires 3 blades for 54 cut. Aggressive blade angle increases air flow to push debris up and out for superior bagging or side discharge. Cleaner, more efficient cutting performance can reduce bagging needs. Gator® Mulcher feature provides efficiency in normal or abrasive conditions. Major brand replacement: AYP.
