XHT 3 REPL HD Blades Simplicity & Snapper 52" Zero Turn 1737252 1737252YP

What It Is

This is the XHT 3 REPL HD (Extra High Tensile 3 Replacement Heavy Duty) blade set for Simplicity and Snapper 52-inch zero-turn mowers. It’s designed for commercial-grade cutting on large properties, handling thick grass and rough terrain without bending or dulling quickly.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Fits only 52-inch cutting decks. Measure your deck width (blade tip to blade tip) to be sure.
• Model compatibility: OEM part number 1737252 or 1737252YP. Fits Simplicity ZT series and Snapper 52" zero-turn models (e.g., ZT2150, ZT2450, ZT2650). Check your owner’s manual or current blade part number.
• Blade dimensions: Each blade is 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch oval drive hole. Measure your old blade’s length, width, and hole pattern to match.
• OEM vs aftermarket: These are genuine OEM Snapper/Simplicity blades. Aftermarket alternatives may have different hole patterns or thinner steel—stick to OEM for guaranteed fit.

Key Things to Know

• Quality: Heat-treated, high-tensile steel with a hardened edge for longer life. Resists warping in high-debris areas. Expect 25–40 hours of cut time before needing replacement.
• Installation difficulty: Moderate. You’ll need a torque wrench (specs: 70–90 ft-lbs), a blade removal tool or block of wood to prevent spinning, and jack stands if lifting the deck. Always disconnect the spark plug first.
• Common gotchas: These blades are not for standard residential zero-turns (e.g., 42" or 48" decks). They’re also not compatible with Snapper rear-engine riders or walk-behinds. If your deck has a spindle guard, check clearance—some aftermarket blades are thicker and may rub.
• Set includes: Three blades (center and two outer) plus washers and bolts. Verify all hardware is present before starting.

Should You Buy It

If you own a compatible Simplicity or Snapper 52" zero-turn and need durable, OEM-spec blades for heavy residential or light commercial use, this set is a solid buy. The high-tensile steel justifies the price for users who mow tough grass or rough ground. Skip it if you need blades for a different deck size or brand—fitment is strict.
