119-8820 Lawn Mower Belt for Toro Timecutter SS5000 MX5000 5000 MX5060 75750 Exmark Quest Zero Turn Mowers, 119-8820-SL Belt with 50 Inch Decks (1/2 x 141-1/2 Inch)

What It Is

This is a replacement drive belt (1/2 x 141-1/2 inches) for 50-inch deck zero-turn mowers, specifically designed to transfer power from the engine to the mower blades on Toro Timecutter and Exmark Quest models.

Fitment & Compatibility

Before buying, confirm:

• Deck size: Must be 50 inches (this belt does not fit 42” or 54” decks).
• Model numbers: Toro Timecutter SS5000, MX5000, 5000, MX5060, 75750; Exmark Quest (check your owner’s manual for exact model number).
• OEM vs aftermarket: This is a direct replacement for OEM part #119-8820. The “-SL” suffix indicates a non-OEM aftermarket belt—same dimensions and function, but not sold in Toro packaging.
• Measure your old belt: Lay it flat and measure length (141.5 inches) and width (0.5 inches). If yours is stretched or worn, match these numbers exactly.

Key Things to Know

• Quality: Aftermarket belt, but reviews are strong (4.5/5). Expect similar lifespan to OEM if deck pulleys are aligned and clean.
• Installation difficulty: Moderate. You’ll need to release belt tension (usually via a spring-loaded idler pulley), route around three spindles, and re-tension. A diagram is helpful—take a photo before removing the old belt.
• Common gotcha: If your deck has a separate “pump drive” belt (for hydrostatic transmission), this is the blade drive belt only. Don’t confuse the two.
• Check pulleys: A worn or seized idler pulley will kill this belt quickly. Spin all pulleys by hand—replace any that are rough or wobbly.

Should You Buy It

Yes, if you need a reliable, budget-friendly replacement for a 50-inch Toro Timecutter or Exmark Quest deck and you’re comfortable with basic belt routing. It’s a solid value at $15—just verify your model and pulley condition first.
