AB4200D Lawn Mower Blades Compatible with ZT4204L 42" Z6 Zero Turn Riding Mower 2 Packs

What It Is

The AB4200D is a set of two replacement lawn mower blades designed for 42-inch cutting decks, specifically compatible with ZT4204L and Z6 Zero Turn riding mowers. They are intended for residential mowing use.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 42 inches. These blades are aftermarket replacements for OEM parts on models like the ZT4204L and Z6 Zero Turn mowers. Measure your existing blade’s length (typically 20.5 inches for this deck size), center hole diameter (usually 5/8 or 7/8 inch), and thickness (around 0.25 inches). Also check the blade’s shape—these are likely standard straight or medium-lift blades. Verify your mower’s brand and model number against the listing; many zero-turn mowers use specific spindle patterns, so measure the distance between mounting holes if applicable.

Key Things to Know

• Quality: At $32.99 for two blades, expect decent steel but not premium hardened edge performance. They may dull faster than OEM or high-end aftermarket blades on tough grass or debris.
• Installation: Easy for DIYers if you have a socket wrench and jack stands; always disconnect the spark plug and remove the spark plug wire before lifting or rotating blades.
• Balance: Aftermarket blades sometimes come slightly out of balance. Before installing, check balance with a simple blade balancer—unbalanced blades cause vibration and spindle wear.
• Reviews: Only 2 reviews so far, so long-term durability is unproven. Consider this a budget option; if you mow wet, thick grass or hit rocks often, these may chip or bend.

Should You Buy It

Buy these if you need a quick, low-cost replacement for a 42-inch ZT4204L or Z6 zero-turn mower and you mow a small, clean lawn without heavy debris. If you mow frequently or on rough terrain, invest in a higher-rated aftermarket or OEM blade set with better steel and more reviews.
