8TEN LawnRAZOR Blade for Murray Snapper ZTS 6000 7500 ZT2142 SC21420 42" Deck 1731898 1731898BZYP (High Lift) 2 Pack

What It Is

The 8TEN LawnRAZOR Blade is a high-lift replacement blade set (2-pack) designed for Murray and Snapper zero-turn mowers with a 42-inch cutting deck. It’s built for heavy lifting and discharge performance, ideal for thick or wet grass where standard blades leave clumps.

Fitment & Compatibility

• Deck size: Fits 42-inch decks only—not 46” or 48”. Measure your deck width before ordering.
• Models: Direct fit for Snapper ZTS 6000, ZTS 7500, ZT2142, SC21420, and Murray equivalents using OEM part numbers 1731898 or 1731898BZYP.
• OEM vs aftermarket: 8TEN is a direct replacement; no adapters needed. Check your current blade’s center hole (typically 1” round) and overall length (approx. 20.5”) to confirm.
• Mounting hardware: Blades come with bolts and washers—use them. Torque to 70–90 ft-lbs per manufacturer spec.

Key Things to Know

• High lift = more power draw: These blades create strong suction, which can bog down a low-horsepower engine. Works best on engines 18 HP or higher.
• Installation difficulty: Easy—just lift deck, remove old blade, install new one with included hardware. Use a blade stop or block to prevent rotation.
• Sharpness: Out of the box, they’re sharp but not razor-edge. Expect a clean cut after a light honing if you want absolute precision.
• Durability: Steel is thicker than many budget blades, but high-lift designs wear faster on the tips in sandy or rocky soil. Check and sharpen every 10 hours of use.

Should You Buy It

If you own a Snapper or Murray 42-inch ZTR with a 1731898 blade and need aggressive discharge for tall or damp grass, this 2-pack is a solid value. It’s not for mulching or bagging—stick to standard lift if you want a finer cut or quieter operation.
