482878 Mower Blades Fit for 36" 52" Deck Lawn Mowers, Mulching Blades 481711 Compatible with A riens Zoom 2252, Gravely Promaster 152Z, Replace Scag 481707 48185 48108 A48108 (3 Pack)

What It Is

This is a 3-pack of aftermarket mulching blades designed to replace OEM blades on 36- and 52-inch zero-turn mower decks, primarily for Ariens Zoom 2252 and Gravely Promaster 152Z models. The mulching design recuts clippings for finer discharge, reducing bagging frequency.

Fitment & Compatibility

• Deck size: Fits 36" and 52" decks only; verify your deck width before ordering.
• OEM cross-reference: Replaces Scag 481707, 48185, 48108, and A48108. Also compatible with Ariens 481711.
• Measure your blade: Center hole diameter must be 5/8". Overall length should be roughly 20.5" – measure your current blade end-to-end to confirm.
• Model check: Confirmed fit for Ariens Zoom 2252 and Gravely Promaster 152Z. Not guaranteed for other brands/decks without cross-referencing OEM part numbers.
• Deck spindle pattern: These are 3-hole blades; ensure your spindles use a 3-bolt pattern (common on these models).

Key Things to Know

• Mulching vs. standard: These blades have a curved, wing-like shape for fine cutting. They will not discharge clippings as far as standard lift blades.
• Installation: Straightforward – remove old blades, note washer order, torque bolts to 70–90 ft-lbs. Use a blade removal tool for safety.
• Quality notes: Aftermarket steel; some users report slightly less balance than OEM. Check balance before installing, and sharpen if needed.
• Common gotcha: Do not use on decks with a dedicated mulching kit that requires a different blade offset. Verify your deck’s blade retention system.

Should You Buy It

Buy if you own an Ariens Zoom 2252 or Gravely Promaster 152Z with a 36" or 52" deck, want a budget-friendly mulching upgrade over standard blades, and are comfortable checking balance and torque specs. Skip if you need a high-lift blade for bagging or have a non-compatible spindle pattern.
