What It Is

This is a cogged drive belt (1/2" x 75 3/8") for Toro TimeCutter and Z-Master zero-turn mowers. It transfers power from the engine to the mower deck, driving the blades.

Fitment & Compatibility

Before buying, confirm your mower’s model number matches one of these: 74820, 74822, 74823, 74824, 74830, 74832, 74833, 74912, 74914. Check the deck size—this belt is for 42-inch or 44-inch decks on those models. Measure your existing belt length (75 3/8 inches) and width (1/2 inch) to verify. OEM Toro part; aftermarket equivalents may vary in tension or durability.

Key Things to Know

• Cogged design reduces slipping and heat buildup vs. a smooth belt, improving blade engagement.
• Installation is moderate—you’ll need to remove the deck and route around pulleys; a belt diagram helps.
• Common gotcha: worn pulleys or a misaligned idler can cause premature belt failure. Check them before replacing.
• Expect 2–3 seasons of use with regular mowing, but inspect for cracks or fraying after 100 hours.

Should You Buy It

Buy this if you own a compatible Toro zero-turn and need a reliable OEM replacement. It’s a direct fit, well-rated, and reasonably priced for the quality. Skip it if your mower model isn’t listed or you want a cheaper aftermarket option.
