Oregon 6 Pack 92-676 Gator Blade Fits John Deere GX20249 GX20819 GX20567 42"

What It Is

This is a set of six Oregon Gator mulching blades (model 92-676) designed for 42-inch John Deere riding mowers. They use a multi-serrated edge to shred clippings finer than standard blades, improving mulch quality and reducing bagging frequency.

Fitment & Compatibility

• Deck size: Must be exactly 42 inches (blades measure 17.75 inches long, 2.5 inches wide, 0.203-inch thick, with a 0.625-inch center hole and 0.375-inch drive pin hole).
• Direct OEM cross: Replaces John Deere parts GX20249, GX20819, and GX20567.
• Check your model: Fits select John Deere 42" decks on X300, X500, D100, D110, D125, D130, D140, D150, D155, D160, D170, LA100, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, L100, L107, L108, L110, L111, L118, L120, L130 models (verify your deck part number before ordering).
• Aftermarket note: Oregon is a reputable aftermarket brand, but aftermarket blades may differ slightly in balance or thickness from OEM—always test fit and spin freely.

Key Things to Know

• Low rating warning: The 2.6/5 star rating (only 2 reviews) suggests possible quality control issues or fitment problems—check recent customer feedback for your specific mower model.
• Installation: Straightforward—lift deck, remove center bolt, replace one blade at a time. Torque center bolt to 40-50 ft-lbs. Use a blade removal tool or block wood to prevent rotation.
• Common gotchas: The drive pin hole (0.375-inch) must align with your spindle’s drive pin. Some John Deere spindles use a different pin size—measure before buying.
• Mulching performance: Serrated edges improve mulching but dull faster on sandy or rocky lawns. Expect to sharpen or replace more often than standard blades.

Should You Buy It

Only buy if you have a confirmed 42-inch John Deere deck with the correct spindle pin size and are comfortable with aftermarket parts. The low rating and limited reviews are red flags—check recent buyer feedback and consider OEM blades if reliability is critical. Best for budget-conscious owners who mulch frequently and don’t mind occasional sharpening.
