483326 5/8" X148 1/2" 522811301 Deck Belt Mower for Husqvarna FD 52M, MZ 52, MZT 52, MZT 52 BF Series Zero-Turns, Scag Freedom Z with 48" and 52" Deck/V-Belt Aramid Cord

What It Is

This is a 5/8" x 148 1/2" V-belt with aramid cord reinforcement, designed to drive the mower deck blades on Husqvarna FD 52M, MZ 52, MZT 52, and MZT 52 BF series zero-turn mowers, as well as Scag Freedom Z models with 48" and 52" decks. It replaces OEM part numbers 483326 and 522811301.

Fitment & Compatibility

Before buying, verify three things: (1) Your deck measures exactly 48" or 52" – this belt won’t fit smaller or larger decks. (2) Your mower model is listed above (Husqvarna FD 52M, MZ 52, MZT 52, MZT 52 BF series, or Scag Freedom Z with 48"/52" deck). (3) Measure your old belt’s length (148.5 inches) and width (5/8 inch) to confirm match. This is an aftermarket belt, not OEM Husqvarna, so check that the aramid cord construction is acceptable for your use (it’s stronger than standard rubber but may wear differently on some pulleys).

Key Things to Know

• Quality: Aramid cord offers higher tensile strength and heat resistance than standard rubber belts, reducing stretch and breakage under heavy use, but it can be slightly stiffer during initial installation.
• Installation: Moderate difficulty – requires removing the deck or accessing the belt routing under the deck. Follow your mower’s manual for tensioning; overtightening can damage pulleys.
• Common gotcha: This belt is 148.5 inches long – some aftermarket belts may be listed as 148" or 149". If yours is an exact match, it’s fine. If not, return it to avoid slipping or poor engagement.
• Lifespan: Expect 200–400 hours depending on mowing conditions (thick grass, debris, or frequent engagement cycles reduce life). Inspect for cracks or fraying every season.

Should You Buy It

Buy this belt if you own a compatible Husqvarna or Scag zero-turn with a 48" or 52" deck and want a budget-friendly, durable replacement that outperforms standard rubber belts. It’s ideal for homeowners or light commercial users who don’t require OEM branding but need reliable deck drive performance. Avoid if you need exact OEM fitment for warranty purposes or have a deck size outside the specified range.
