XHT 2 USA Made Blades Snapper Simplicity 1758878 1758878BMYP ZT2342 ZPX2342 42"

What It Is

This is a set of three 42-inch XHT (Extra Hard Tempered) steel blades designed for Snapper and Simplicity zero-turn mowers with 42-inch decks. They’re for heavy-duty residential or commercial cutting—tough grass, frequent mowing, or rough terrain.

Fitment & Compatibility

• Check deck size: Only fits 42-inch cutting decks. Measure deck width if unsure.
• Model compatibility: Direct replacement for Snapper/Simplicity OEM part numbers 1758878 and 1758878BMYP. Fits Snapper ZT2342, ZPX2342, and similar 42-inch zero-turn models. Also fits Simplicity ZT2342, ZPX2342, and some Broadmoor/Regent series with 42-inch decks.
• Measurements: Blade length is 42 inches overall (three 14-inch blades). Center hole diameter is typically 5/8 inch; check your spindle hole size before ordering.
• OEM vs aftermarket: These are aftermarket blades, but made in USA and often match OEM specs. Verify blade thickness (usually 0.204 inch) and lift height match your originals.

Key Things to Know

• Quality: XHT steel stays sharp longer than standard blades, but is more brittle—avoid hitting rocks or roots.
• Installation: Moderate difficulty. You’ll need a torque wrench (specs: 50-60 ft-lbs on spindle nuts). Use lock washers or thread locker.
• Common gotcha: These blades are not universal—will not fit 42-inch decks from other brands (e.g., John Deere, Toro) without adapter kits.
• Performance: Gives a clean cut in dense grass, but may produce more vibration if not balanced before install. Always check blade balance.

Should You Buy It

Buy it if you own a Snapper or Simplicity 42-inch zero-turn mower and want a durable, USA-made blade upgrade that outlasts standard OEM steel. Skip if you need a universal fit or mow over debris regularly—the extra hardness means less forgiveness on impact.
