ELITEWILL GX22151 GY20850 2pcs Lawn Mower Mulching Blades Fit for John Deere 42'' D100, D110, D120, D130, Z225, Z235, D125 Replaces OEM # AM141033 AM131033 AM137333

What It Is

This is a 2-pack of ELITEWILL mulching blades designed to replace the OEM blades on John Deere 42-inch cutting decks. Mulching blades feature a curved, serrated edge that recuts grass clippings into fine particles, returning nutrients to the lawn. They are ideal for users who want to skip bagging and leave a clean, natural finish.

Fitment & Compatibility

• Deck size: Fits only 42-inch (107 cm) John Deere mower decks. Measure your deck width before ordering—blades are 21 inches long.
• Models: Compatible with D100, D110, D120, D125, D130, Z225, Z235, and similar 42-inch deck models.
• OEM replacements: Replaces John Deere part numbers AM141033, AM131033, and AM137333. Check your current blade part number (stamped on the blade) to confirm.
• Center hole: 1-inch diameter with a 5-point star drive. Verify your spindle matches this pattern—most John Deere 42-inch decks use it, but older or non-standard spindles may not.
• Aftermarket note: ELITEWILL is a third-party brand. Fit is generally accurate, but tolerances can vary slightly from OEM. If you have a tight spindle or unusual bolt pattern, measure the blade length and hole dimensions.

Key Things to Know

• Mulching vs. standard: These blades are for mulching only. They will not perform well for bagging or side-discharge—switch to standard blades for those tasks.
• Installation: Requires a socket wrench (usually 15/16” or 5/8” depending on your mower). Remove the old blade, clean the spindle, and torque the new blade to 40-50 ft-lbs. Do not overtighten.
• Sharpness: Blades come pre-sharpened but may need a light touch-up with a file after a few uses to maintain cutting quality.
• Balance check: Always balance new blades before installing. An unbalanced blade causes vibration, poor cut, and spindle wear. Use a blade balancer or hang it on a nail.

Should You Buy It

If you own a John Deere with a 42-inch deck and want an affordable, well-reviewed mulching blade set for regular lawn maintenance, this is a solid buy. It’s not for heavy-duty commercial use or for decks outside the listed models—double-check your deck size and spindle pattern first. For the price, it’s a reliable way to keep your mulching game sharp.
