119-3321 Lawn Mower Drive Belt Fits for Exmark Toro 119-3321 TimeCutter ZS5000 SS5000 SS5060 and MX5060 Riding Mowers (1/2" x 64")

What It Is

This is a replacement drive belt (1/2" x 64") for Exmark and Toro zero-turn mowers, specifically models in the TimeCutter and SS/MX series. It transfers power from the engine to the hydrostatic pumps, enabling forward/reverse movement—not the blades.

Fitment & Compatibility

Check your mower’s model number — this belt is designed for Exmark Lazer Z and Toro TimeCutter ZS5000, SS5000, SS5060, and MX5060 models. It also fits some Toro Z Master and Exmark Radius units. Do not rely on the mower’s deck size alone (e.g., 50" or 60" deck); verify your model number against the OEM part cross-reference (Toro part 119-3321). Measure your existing belt: it must be exactly 1/2" wide and 64" long (outside circumference). OEM vs. aftermarket: this is a genuine Toro belt, so no quality variance. If you have a different model, check your manual or a parts lookup tool before buying.

Key Things to Know

• Quality & lifespan: OEM belt, good for 200–400 hours with normal use. Inspect for cracking or fraying annually.
• Installation difficulty: Moderate. You’ll need to remove the deck or access the belt routing under the mower. A diagram is helpful—take a photo before removing the old belt.
• Common gotcha: This belt drives the wheels, not the blades. If your mower moves but blades don’t spin, you need a different belt. Also, the belt must be routed correctly around idler pulleys—wrong routing causes slippage or premature wear.
• Price point: $18.99 is competitive for OEM; aftermarket belts may be cheaper but often wear faster or have fitment issues.

Should You Buy It

If you own one of the listed Exmark or Toro models and need a reliable, direct-fit replacement for the drive belt, this is a solid choice. It’s a genuine OEM part at a fair price, so you avoid the guesswork of aftermarket belts. Skip it if your mower model isn’t confirmed compatible, or if you’re looking for a deck/blade belt.
