MowerPartsGroup (3) Mulching Blades for Snapper & Simplicity 48" Decks 038-4827-00, 1520843

What It Is

This is a set of three mulching blades designed for Snapper and Simplicity 48-inch commercial or residential zero-turn mowers. They replace OEM part numbers 038-4827-00 and 1520843, and are intended for use on decks that require a triple-blade mulching setup.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: These blades fit 48-inch decks only. Measure your deck width if unsure.
• Model/brand: Designed for Snapper and Simplicity zero-turn mowers with 48" fabricated decks. Common models include Snapper 150Z, 250Z, and Simplicity ZT series. Check your owner’s manual for OEM part number 038-4827-00 or 1520843.
• Blade dimensions: Each blade is 16.5 inches long, with a 1-inch center hole and 0.25-inch thickness. Measure your current blade length, hole size, and thickness to verify fit.
• Aftermarket note: This is an aftermarket replacement, not OEM. Quality is generally good, but check that the blade shape matches your deck’s mulching baffles (some aftermarket blades have slightly different curvature).

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque to 70-80 ft-lbs.
• Mulching performance: These blades have a higher lift and sharper cutting edge than standard blades, producing finer clippings for better mulching. They are not designed for bagging or side discharge.
• Durability: Made from heat-treated steel. Expect similar lifespan to OEM blades (25-50 hours depending on debris). Sharpen or replace when edges dull.
• Gotcha: Some users report the blades are slightly thinner than OEM, which can cause vibration if not balanced. Always balance after installation.

Should You Buy It

If you have a Snapper or Simplicity 48-inch zero-turn with a triple-blade deck and primarily mulch, this is a solid, cost-effective replacement. It’s not for bagging or discharge use, and you’ll need to balance them yourself. For the price, it’s a good value over OEM, but double-check your deck type and blade dimensions first.
