AB4200D Blade Fit for EGO Power+42" Z6 Zero Turn Riding Mower ZT4204L, 21" Mulch Mower Blades (2 Pack)

What It Is

This is a 2-pack of 21-inch mulch mower blades designed for the EGO Power+ 42" Z6 Zero Turn Riding Mower (model ZT4204L). It’s intended to replace worn or damaged blades for improved grass cutting and mulching performance on that specific machine.

Fitment & Compatibility

• Exact fit: Only for EGO Power+ Z6 ZT4204L 42” zero turn mower. Not compatible with other EGO models or brands.
• Deck size: 42-inch deck requires two blades (this pack covers one full set).
• Measurements: Blade length is 21 inches (center hole to tip). Check your existing blade’s length, center hole diameter (likely 5/8” or 7/16”), and thickness (typically ~0.25”). Confirm these match before buying.
• OEM vs aftermarket: This is an OEM EGO part (AB4200D), so no fitment guesswork if your mower is the ZT4204L. Aftermarket blades may not match the exact offset or hole pattern.

Key Things to Know

• Poor reviews: 2.1/5 stars from 8 reviews—common complaints include dullness out of the box, premature wear, and balance issues. Inspect and balance before installation.
• Installation difficulty: Easy—jack up mower, remove center bolt, swap blades. Use a torque wrench (40-50 ft-lbs) and re-check after first mow. No special tools needed.
• Mulching vs bagging: These are mulch blades (curved, with more surface area). They’ll leave finer clippings but may not perform well for bagging or side discharge. If you bag, consider standard lift blades.
• Durability concern: Multiple users report chipping or bending after a few uses on rocky or root-heavy lawns. Not ideal for rough terrain.

Should You Buy It

Buy only if you own an EGO ZT4204L and need OEM replacements for mulching. Given the low rating, try a single pack first—or consider aftermarket alternatives (e.g., Oregon or Rotary) that match the 21” length and hole pattern, which often offer better durability at a similar price. Avoid if you bag or mow debris-heavy lawns.
