Lawn Mower Cogged Pump Belt for Exmark Toro 119-3321 V-Belt, for Toro TimeCutter ZS5000, SS5000, SS5060 and MX5060, for Exmark Quest Riding Mowers (1/2 x 64 inch)

What It Is

This is a cogged V-belt (1/2 x 64 inches) that drives the mower deck’s pump or spindle system on select Toro TimeCutter and Exmark Quest riding mowers. It’s designed for machines with a 50-inch or 60-inch deck that use a belt-driven pump for deck lift or blade engagement.

Fitment & Compatibility

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

• Toro TimeCutter ZS5000 (50-inch deck), SS5000, SS5060, and MX5060 (all 60-inch decks)
• Exmark Quest (any deck size, but primarily 50-inch and 60-inch models)

Check these specifics:

• OEM cross-reference: This belt replaces Toro part #119-3321. If your mower uses a different OEM number, it won’t fit.
• Measurements: Belt is 1/2 inch wide and 64 inches long (outside circumference). Measure your old belt or the pulley path to verify.
• Cogged vs. smooth: Cogged belts are more flexible and run cooler than smooth V-belts. Ensure your pulley system accepts cogged design (most do, but check for debris buildup).
• Not universal: Will not fit Toro TimeCutter models with 42-inch or 48-inch decks, or older Exmark Lazer Z or Turf Tracer models.

Key Things to Know

• Quality concerns: With a 3.4-star rating and only 3 reviews, this belt may have fitment or durability issues. One common complaint is premature wear or slipping under heavy use. Expect it to last 1-2 seasons on residential mowers.
• Installation difficulty: Moderate. You’ll need to remove the deck belt cover, release belt tension (usually via a spring-loaded idler pulley), and route the belt correctly. Watch for belt routing diagrams on the deck or in your manual.
• Gotchas: Double-check belt length—64 inches is critical. A 63-inch belt won’t fit, and a 65-inch will slip. Also, ensure the belt is seated fully in all pulley grooves; a misrouted belt can snap quickly.
• Warranty: Aftermarket belt; no OEM warranty. If your mower is under factory warranty, using this belt may void it.

Should You Buy It

Buy this belt only if you need a budget-friendly, quick replacement for a Toro TimeCutter ZS5000, SS5000, SS5060, or MX5060, or an Exmark Quest with a 50- or 60-inch deck, and you’re comfortable with moderate DIY installation. If you demand long durability or have a high-use commercial mower, spend more on an OEM Toro belt (part #119-3321) or a premium aftermarket brand like Gates or Kevlar-reinforced belts.
