OEP 598-631 Gator G5 Mulching Blade (21")
Last verified by the Lifetime Picks Editorial Team
Why we picked it
Gator-tooth profile lifts clippings for repeated re-cutting (finer mulch)
Oregon's Gator G5 mulching blade is the aftermarket lawn mower blade r/Lawncare, r/Landscaping, and r/HomeImprovement consistently recommend over the OEM blade that shipped with your mower. The Gator-tooth profile (the namesake — the teeth on the back edge of the blade) lifts the grass clippings up into the deck for repeated re-cutting before they exit, producing finer mulch that decomposes in days rather than weeks. The G5 is Oregon's heaviest gauge (5/16" thick), 21" length fits most walk-behind mowers. The heat-treated steel holds an edge through a season of weekly mowing; sharpening with a file or grinder restores it. Oregon has manufactured cutting components in Portland since 1949.
