M87622 AM100538 M141785 Six Mower Blades Fits John Deere 60 420 430 425 435

What It Is

This is a six-pack of aftermarket mower blades (OEM cross-reference M87622, AM100538, M141785) designed for John Deere 60-inch deck models, including the 420, 430, 425, and 435 series. Used for medium to large residential or commercial mowing.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 60-inch deck (not 48” or 54”). Measure deck width if unsure.
• Model series: Fits John Deere 420, 430, 425, 435, and similar 60” deck tractors. Does not fit older or smaller models like the LX or X300 series.
• OEM numbers: Cross-references to John Deere M87622, AM100538, and M141785. Compare your old blade’s part number or measure blade length (typically 20.5” on these). Center hole diameter is usually 1” or 5/8” – confirm yours.

Quick check: If your current blade has a part number starting with M87622, AM100538, or M141785, these will fit. If not, measure length and hole size.

Key Things to Know

• Quality: Aftermarket, not OEM. Expect good durability for residential use, but may not match OEM steel hardness for heavy commercial cutting.
• Installation: Straightforward – remove old blades, match orientation (cutting edge facing rotation direction), torque to spec (~70-90 ft-lbs). No special tools needed beyond a socket wrench.
• Common gotcha: These blades are not universal – they only fit the specific 60” decks listed. Don’t assume they fit other John Deere models or non-Deere decks.
• Value: Six blades for $99.99 is cheaper than buying OEM individually. Good for multiple mowers or seasonal replacements.

Should You Buy It

Buy this if you own a John Deere 420/430/425/435 with a 60-inch deck and want a cost-effective blade pack for regular residential mowing. Skip it if you need OEM-grade durability for commercial use, or if your deck size/model isn’t listed – fitment is narrow.
