A ABIGAIL 3 Pack 48" Deck Mower Mulching Blades Compatible with John Deere D140 E140 D160 E160 E170 E150 LA145 LA140 LA155 155C 48" Deck Lawn Mower Replaces GY20852 GX21784 AM137757 AM141035

What It Is

This is a 3-pack of 48-inch mulching blades designed for John Deere lawn tractors with a 48-inch deck. They replace OEM part numbers GY20852, GX21784, AM137757, and AM141035, and are intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck (measure deck width if unsure). These blades fit John Deere models D140, E140, D160, E160, E170, E150, LA145, LA140, LA155, and 155C. They are aftermarket replacements, not OEM John Deere parts, so check that your existing blade dimensions (length, width, center hole, and offset) match. The ABIGAIL blades are 48-inch long, with a 1-inch center hole and 0.25-inch thickness—verify these against your current blade. If your mower uses a different spindle or blade design (e.g., high-lift for bagging), these mulching blades won’t work.

Key Things to Know

• Quality vs OEM: These are budget-friendly aftermarket blades. Some users report they are slightly thinner or less durable than genuine John Deere blades, but still effective for average homeowner use.
• Installation difficulty: Easy, but you need a socket wrench and a blade removal tool (or a block of wood to prevent rotation). Always disconnect the spark plug before working under the deck.
• Common gotcha: Mulching blades have a more curved profile than standard blades. Ensure your deck is clean and blades are sharp for best mulching performance. Dull blades tear grass, not cut it.
• Pack size: You get three blades, enough for one full deck swap (most 48-inch decks use three blades). Check your deck’s blade count—some models use two.

Should You Buy It

This is a solid choice if you want a cost-effective mulching blade set for a John Deere 48-inch deck and don’t need heavy-duty commercial durability. It’s best for homeowners who mow frequently and want finer clippings for lawn health, but avoid it if you need high-lift blades for bagging or if your mower uses a different blade pattern.
