(Set of 2) 42 Inch High-Lift Mower Blades for EGO Power+ 42" Z6 Zero-Turn Riding Mower ZT4204L ZT4200, Fits T6 Riding Mower TR4204, Replaces OEM AB4200 AB4200D

What It Is

This is a set of two 42-inch high-lift mower blades designed for EGO Power+ 42" zero-turn and riding mowers. High-lift blades create stronger airflow to lift grass for a cleaner cut and better bagging, ideal for thick or damp grass.

Fitment & Compatibility

• Deck size: Only for 42-inch cutting decks. Do not use on 36" or 52" EGO mowers.
• Models confirmed fit: EGO Z6 ZT4204L, ZT4200 (zero-turn), and T6 TR4204 (riding mower). Check your model number on the frame sticker.
• OEM replacement: Replaces EGO part #AB4200 and AB4200D. Aftermarket set, not OEM.
• Measurements before buying: Blade length must be exactly 21 inches (each blade) with a 5-point star center hole and 0.25-inch diameter. Measure your current blade’s length, center hole shape, and thickness (should be ~0.1875 inches). If your blade has a different hole pattern or length, these won’t fit.

Key Things to Know

• Installation difficulty: Easy – 15-20 minutes with a socket wrench. Lift deck, block securely, remove center bolt, swap blades, torque to 50-60 ft-lbs.
• Common gotcha: High-lift blades increase power draw. If your mower bogs in tall grass, switch to standard-lift blades to reduce load.
• Quality note: Aftermarket steel may be slightly thinner than OEM. Check for balance out of the box – if one side is heavier, file the heavy side until balanced.
• Sharpening: Can be sharpened 2-3 times before replacement. Do not sharpen beyond the hardened edge or you’ll reduce lift.

Should You Buy It

Buy if you need a budget-friendly replacement for your EGO 42" mower’s high-lift blades and are comfortable with aftermarket parts. Avoid if you want OEM fit precision, have a different deck size, or mow very light grass where low-lift blades suffice.
