M115496 Mulching Blades Fit for John Dee re 54" Decks, GY20569 Toothed Mower Blades for JD 345 325 335, Scotts GT2554 S2554 Tractor, Replace M111523, M113518, M115329, 3 Pack

What It Is

This is a 3-pack of mulching blades designed to replace OEM parts on John Deere 54-inch decks and select Scotts/John Deere lawn tractors. The toothed edge design chops clippings finer for improved mulching and nutrient recycling.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Only for 54-inch decks (not 48" or 42").
• Model list: Fits John Deere 345, 325, 335, and Scotts GT2554, S2554. Also replaces OEM part numbers M111523, M113518, M115329.
• Measurements: Overall length is 20.5 inches (center hole to tip), center hole diameter 0.75 inches. Measure your old blade to verify.
• Note: Aftermarket blades may have slight differences in thickness or balance compared to OEM – always check deck clearance before installing.

Key Things to Know

• Quality concerns: At 3.9 stars from 33 reviews, some users note blades may bend on rocks or thick debris – avoid heavy-duty use.
• Installation: Easy bolt-on swap with a socket wrench. Use a torque wrench to tighten to 70-90 ft-lbs (check your manual).
• Mulching vs. bagging: These are mulching blades – not ideal if you bag clippings regularly. They leave finer clippings on the lawn.
• Balance check: Aftermarket blades sometimes arrive unbalanced. Spin-check before mounting; if wobbling, sharpen or replace.

Should You Buy It

Buy this set if you own a compatible 54-inch John Deere or Scotts tractor, want an affordable mulching blade upgrade, and don’t mow rocky or debris-heavy lawns. For heavy-duty cutting or bagging, stick with OEM or heavier-duty aftermarket blades.
