AB4200D Mower Blade Set Compatible with EGGO Power+ 42"Z6 Zero Turn Riding Mower Models ZT4204L, 2 Pack 21 Inch Mulch Lawn Mower Blade

What It Is

This is a 2-pack of 21-inch mulching blades designed for EGGO Power+ 42" Z6 zero-turn mowers, specifically the ZT4204L model. They replace OEM blade set 5653275, intended for fine grass clipping mulching on residential zero-turn decks.

Fitment & Compatibility

Check before buying:

• Deck size: Only fits 42-inch cutting decks (not 36" or 48").
• Model number: Confirmed for EGGO Power+ Z6 ZT4204L. Verify your mower’s model plate (under seat or on frame).
• OEM cross-reference: Replaces EGGO part 5653275. Aftermarket, not OEM—expect slight thickness/tolerance differences.
• Measurements: Each blade is 21" long, center hole 5/8" diameter, offset 1/2". Measure your old blade’s length and hole size to confirm.
• Not compatible with EGGO Z6 ZT4200L, ZT4202L, or older ZT models—check your manual.

Key Things to Know

• Mulching vs. bagging: These are mulching blades (curved, with extra surface area). They chop clippings finer but won’t lift as well for bagging or side discharge. If you bag often, consider high-lift blades instead.
• Installation: Medium difficulty—you’ll need a torque wrench (specs: 55-65 ft-lbs) and thread lock. Blades are sharp; wear gloves. Balance-check after install (hang on a nail).
• Durability: Heat-treated steel, but some users report faster dulling than OEM. Expect to sharpen or replace every 20-30 hours of mowing on thick grass.
• Fitment note: Some buyers report needing to grind the center hole slightly for a perfect fit on ZT4204L. Check clearance before tightening.

Should You Buy It

This is a budget-friendly option if you’re okay with aftermarket mulching blades for your EGGO Z6 ZT4204L and primarily mulch grass. Not ideal if you bag often or want OEM-level durability—stick with 5653275. For the price, it’s a solid value if you confirm fitment and don’t mind occasional balancing or minor fitting adjustments.
