What It Is

This is a set of six (6) aftermarket “Reaper” blades designed for zero-turn mowers with 36” to 52” cutting decks. They are meant for high-volume commercial or residential mowing where sharp, efficient cutting is needed.

Fitment & Compatibility

Before buying, verify these four things:

1. Deck size: Fits 36”, 48”, 52” decks (confirm your exact deck width).
2. Brand/model: Compatible with Exmark, Ferris, Ariens, Gravely, Husqvarna, John Deere, Scag, and Toro zero-turn mowers. Check your mower’s model number against the OEM part numbers listed: 103-6580-S, 5021227S, 03253800, 539100341, AM104490, 481707.
3. OEM vs aftermarket: This is an aftermarket set, not OEM. Quality is high, but fitment may vary slightly on older decks.
4. Measurements: Each blade is likely 15.5–16.5” long with a 5-point star center hole. Measure your existing blade’s length and center hole shape (star vs. oval) to confirm.

Key Things to Know

• Installation: Moderate difficulty – you’ll need a torque wrench (spec 70–90 ft-lbs) and a blade removal tool. Use thread locker on bolts.
• Quality: Heat-treated steel with a hardened edge. Rated 5.0/5 from 14 reviews – users report they stay sharp longer than OEM for the price.
• Gotcha: These are “Reaper” style (slight lift, aggressive cut). They may produce more clumping in wet grass compared to standard lift blades.
• Set of six: Good for triple-blade decks (e.g., 52” Toro Grandstand). Verify your deck uses six blades total.

Should You Buy It

Buy this if you have a zero-turn mower from one of the listed brands with a 36–52” deck, and you want a durable, sharp aftermarket blade set at a lower cost than OEM. It’s ideal for commercial operators who need consistent cutting and don’t mind a slightly more aggressive blade profile. Skip it if you prefer OEM-only parts or need standard lift blades for wet conditions.
