Drive Belt 1/2" X141.5" for Toro 50 Inch Deck TimeCutter SS5000 SS5060 ZS5000 MX5060 119-8820 120-3892

What It Is

This is a replacement drive belt for Toro TimeCutter and ZS5000 series zero-turn mowers with a 50-inch deck. It transfers power from the engine to the transmission, enabling forward and reverse movement.

Fitment & Compatibility

Before buying, confirm your mower model: SS5000, SS5060, ZS5000, or MX5060 with a 50-inch deck only. This belt is 1/2 inch wide by 141.5 inches long, matching OEM part numbers 119-8820 and 120-3892. It is a direct OEM replacement, not a universal aftermarket belt, so it fits without modification. Check your old belt’s part number or measure its length (end-to-end, not loop) to verify. Avoid using this on 42-inch or 54-inch deck models—it will be the wrong length.

Key Things to Know

• OEM quality: Genuine Toro belt, not a generic substitute. Expect better durability and fit than off-brand belts.
• Installation difficulty: Moderate. Requires removing the deck belt and routing around pulleys and idlers. A belt diagram or service manual helps.
• Common gotcha: The belt is tensioned by a spring-loaded idler. If you don’t release tension properly, you risk damaging the belt or pulley.
• Wear indicator: Replace if you see cracking, glazing, or fraying, or if the mower hesitates or slips during turns.

Should You Buy It

If you own a Toro TimeCutter or ZS5000 with a 50-inch deck and need a reliable, exact-fit replacement, this is the right belt. It’s a solid OEM choice for DIY maintenance, but if your mower is under warranty, check with a dealer first. For other deck sizes, keep looking.
