Lawn Mower Parts 119-8820 Deck Belt for Toro TimeCutter SS5000 MX5000 5000 MX5060 75750 Exmark Quest Zero Turn Mowers

What It Is

This is a replacement deck drive belt (OEM part 119-8820) for select Toro TimeCutter and Exmark Quest zero-turn mowers. It connects the engine pulley to the mower deck spindles to spin the blades.

Fitment & Compatibility

Before buying, verify your mower model and deck size. This belt fits:

• Toro TimeCutter SS5000 (model 75750)
• Toro TimeCutter MX5000 (model 75750)
• Toro TimeCutter 5000 (model 75750)
• Toro TimeCutter MX5060
• Exmark Quest (select models with 50" or 60" decks)

Check these specifics:

• Deck size must be 50" or 60" – will not fit 42" or 48" decks.
• OEM part number 119-8820; aftermarket equivalents may vary slightly in length (measure old belt if replacing with non-OEM).
• Belt dimensions: 1/2" wide, roughly 140" long (measure end-to-end if unsure).
• Verify your mower’s serial number range if possible – some early TimeCutter models use a different belt.

Key Things to Know

• Quality: OEM Toro belt is durable and matches original specs; aftermarket belts may wear faster or slip on pulleys.
• Installation difficulty: Moderate – requires removing the deck or using a belt tensioner tool. Expect 30-60 minutes for first-timers.
• Common gotchas:
  • Belt routing is critical – check the diagram under the deck or in your manual before installing.
  • Tensioner spring can snap if over-stretched; support the pulley when releasing tension.
  • A worn belt may look fine but cause uneven cutting or blade slip – replace if cracked, glazed, or frayed.
• Lifespan: Typically 1-2 seasons with normal use; replace sooner if mowing in dusty or wet conditions.

Should You Buy It

If you own a Toro TimeCutter SS5000, MX5000, or Exmark Quest with a 50" or 60" deck and need a direct OEM replacement, this belt is a reliable choice. It’s a straightforward fix for uneven cutting or belt failure, and the price is fair for a genuine part. Skip it if you have a different deck size, non-compatible model, or prefer a cheaper aftermarket option (but expect shorter life).
