Swisher 20655 50" Blade Belt (2-(Pack))

What It Is

The Swisher 20655 is a genuine OEM replacement V-belt designed for 50-inch Swisher zero-turn and trail mowers. It connects the engine pulley to the blade spindles, powering the cutting deck. This 2-pack provides a spare for quick swaps.

Fitment & Compatibility

• Deck size: Only for 50-inch Swisher mower decks. Do not use on 44-inch, 60-inch, or other widths.
• Model check: Confirmed fit for Swisher ZTR 1250, ZTR 1550, and ZTR 1850 series. Also compatible with Swisher T-50 tow-behind mowers.
• Measurements: Belt is 1/2-inch wide x 175-inch length (approx). Measure your existing belt to confirm—especially if your mower is older or has been modified.
• OEM vs aftermarket: This is genuine Swisher, not a generic. Aftermarket belts (e.g., Stens, Oregon) may cost less but often have shorter life or different tension specs. Stick with OEM if you want exact fit.
• What to check before buying: Verify your deck spindle pulleys are in good condition and aligned. A worn pulley will shred a new belt fast. Also check the belt routing diagram under your deck—Swisher changed routing on some late-model ZTRs.

Key Things to Know

• Quality: Genuine Swisher belts are made of EPDM rubber with aramid cord—decent for residential use but not heavy commercial. Expect 1-2 seasons under normal mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck belt guard, loosen the tensioner pulley, and snake the belt around spindles. A belt tensioner tool helps. Allow 30-45 minutes for a first-timer.
• Common gotcha: The belt is directional. Look for an arrow on the belt surface indicating rotation direction. Install backward and it will slip or wear unevenly.
• Pack of 2: Good for keeping one as a spare, but note that belts degrade in storage (heat, UV). Store the spare in a cool, dark place.

Should You Buy It

Buy this if you own a 50-inch Swisher ZTR or trail mower and want a guaranteed fit with minimal hassle. The 2-pack is a smart value for seasonal users who mow 1-2 acres weekly. Skip it if you’re on a tight budget—aftermarket belts can work for half the cost—or if your mower is a different brand/deck size.
