42" Deck Mower Blades Fit for EGO Power+ ZT4204L E6 Z42 Z6 Zero Turn Riding Mower Replaces OEM AB4200D 2 Pack

What It Is

This is a 2-pack of 42-inch replacement blades for EGO Power+ zero-turn mowers, specifically the ZT4204L, E6, Z42, and Z6 models. They are designed to cut grass efficiently on residential or commercial zero-turn decks, offering a direct replacement for OEM part AB4200D.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 42 inches (measure from blade tip to blade tip if unsure). These blades are listed for EGO models ZT4204L, E6, Z42, and Z6—check your owner’s manual or deck sticker for the exact model number. They replace OEM AB4200D, but aftermarket blades can vary slightly in hole pattern, thickness, or offset. Measure the center hole diameter (typically 1 inch) and the distance between mounting holes (usually 3 inches) to confirm. If your mower uses a different blade length or bolt pattern, these won’t fit.

Key Things to Know

• Quality: At 4.3 stars from 226 reviews, these blades are generally well-regarded for sharpness and durability, but some users report they dull faster than OEM. Expect a 1-2 season lifespan with regular use.
• Installation: Easy to swap with basic tools (socket wrench, torque wrench). Use a blade-stopping tool or block the deck to prevent rotation. Torque bolts to 40-50 ft-lbs—over-tightening can strip the spindle.
• Common Gotchas: Check blade balance after installation—unbalanced blades cause vibration and uneven cut. Also, ensure the blades are oriented correctly (air-lift side up). If your deck has mulching plugs, these are standard lift blades, not mulching-specific.
• Sharpening: You can sharpen them, but the coating may wear off quickly. For best results, replace after noticeable dulling.

Should You Buy It

Buy these if you need a budget-friendly, direct-fit replacement for your EGO 42-inch zero-turn and don’t mind slightly shorter blade life than OEM. They’re a solid choice for homeowners with light to moderate mowing—just verify fitment and balance before use.
