What It Is

These are high-lift replacement blades for 50-inch cutting decks, designed to improve grass discharge and bagging performance. They fit Simplicity and Snapper zero-turn and lawn tractor models, including the ZT2050, ZT2450, S-Napper LT200, and YT400 series.

Fitment & Compatibility

• Deck size: Must be a 50-inch deck. Measure your deck width before buying.
• OEM cross-references: Replaces 1708229A, 1726453A, 1708229SM, 1716697ASM.
• Blade dimensions: 3-blade set. Each blade is 16.5 inches long, 0.25 inches thick, with a 1-inch center hole and 7/8-inch diameter hub. Check your existing blade’s length and hole size.
• Model compatibility: Verified for Simplicity ZT2050, ZT2450, S-Napper LT200, YT400 series. Not guaranteed for other brands or decks without measuring.
• Aftermarket note: This is a non-OEM (Lift brand) part. It may have slight finish or balance differences from original Simplicity blades.

Key Things to Know

• High lift = more suction: Better for bagging and side-discharge of wet or tall grass. Not ideal for mulching—consider a mulching blade if you prefer leaving clippings.
• Installation: Standard 3-blade swap. Use a torque wrench to tighten bolts to manufacturer spec (typically 70-80 ft-lbs). Check blade balance before installing—unbalanced blades cause vibration and deck wear.
• Common gotcha: These blades may not fit decks with a different spindle pattern or if your deck uses a different center hole size (e.g., 5/8-inch). Verify physical dimensions against your old blade.
• Durability: High-lift blades wear faster than standard blades due to increased air resistance. Inspect monthly for dullness or bending.

Should You Buy It

If you have a 50-inch Simplicity or Snapper deck and want strong bagging or side-discharge performance, this is a solid, affordable replacement. Avoid if you primarily mulch or have a non-compatible deck size/spindle.
