Aeagle GY20852 Mulching Toothed Blades for John Deere 48 Inch Deck Mower D140 D160 S140 E170 LA145 Z355E D155 E140 E160 LA130 100 Series 48" Zero Turn Lawn Tractor AM141035, 7 Point Star, 3 Pack Blue

What It Is

The Aeagle GY20852 is a set of three mulching toothed blades designed to replace OEM AM141035 blades on John Deere 48-inch decks. They are intended for cutting grass and finely mulching clippings, reducing bagging needs.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 48 inches (measured blade tip to tip). These blades fit John Deere D140, D160, S140, E170, LA145, Z355E, D155, E140, E160, LA130, and most 100 Series tractors with a 48-inch deck. They also work with select zero-turn models using the same blade pattern. The blades have a 7-point star center hole and a 3.75-inch blade length (actual measurements: 16.5 inches long, 2.5 inches wide, 0.25 inches thick). Verify your current blades match these dimensions and that your spindle uses a 7-point star drive. Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality vs OEM: Made from heat-treated steel, but may be slightly thinner or softer than genuine John Deere blades. Expect shorter lifespan under heavy use or rocky conditions.
• Installation: Easy bolt-on replacement if your deck uses the 7-point star pattern. Torque bolts to 70-80 ft-lbs. Check for bent spindles before installing.
• Mulching performance: Toothed design chops clippings finer than standard lift blades, but may leave clumps in wet grass. Use with a mulching plug or cover for best results.
• Balance check: Aftermarket blades sometimes arrive unbalanced—test on a blade balancer before mounting to avoid vibration.

Should You Buy It

Buy this set if you own a compatible John Deere 48-inch deck, want a budget-friendly mulching upgrade over standard blades, and don’t mind replacing them more often than OEM. It’s ideal for homeowners mowing dry, clean lawns. Skip it if you need heavy-duty durability for commercial use or frequently hit debris.
