Woniu Replacement Lawn Mower 54 inch Deck Belt for Toro 130-0843, 130-0843-SL; Toro TimeCutter 74740,74741,74768,74778 Mower

What It Is

This is a 54-inch deck drive belt for Toro TimeCutter zero-turn mowers. It transfers power from the engine pulley to the deck spindles, spinning the blades for cutting grass. Designed to replace OEM part numbers 130-0843 and 130-0843-SL.

Fitment & Compatibility

• Exact fit for: Toro TimeCutter models 74740, 74741, 74768, 74778 (all with 54-inch decks).
• Check your model number: Look on the mower’s frame or under the seat—not the engine. The belt will not fit 50-inch or 60-inch decks.
• OEM vs aftermarket: This is a non-OEM replacement. Length and width match OEM specs (roughly 130.5 inches long, 1/2 inch wide), but material and construction may differ.
• Measure your old belt: Confirm it’s a 5/8-inch width belt (common for Toro 54-inch decks) to avoid mismatch. If your belt is a different width, this won’t fit.
• Deck type: Works only with stamped steel 54-inch decks on these specific TimeCutter models—not fabricated decks or other Toro series.

Key Things to Know

• Quality variance: At $22, this is a budget option. Some users report shorter lifespan (1-2 seasons) compared to OEM belts (3-5 seasons). Inspect for fraying or cracking annually.
• Installation difficulty: Moderate. You’ll need to remove the deck or use a spring tool to release tension. Follow a Toro TimeCutter deck belt diagram (available online) to route correctly—wrong routing causes slipping or blade disengagement.
• Common gotcha: The belt may be slightly tighter or looser than OEM. If you hear squealing or the deck blades stop under heavy grass, re-check routing and tensioner position. A loose belt can cause premature wear.
• Deck removal helpful: For first-time installers, removing the deck makes routing much easier. Expect 30-45 minutes total.

Should You Buy It

If you’re on a tight budget and comfortable with occasional belt replacements, this is a functional stopgap. It works for light-to-medium mowing (1-2 acres per week) and saves about $15-20 over OEM. However, if you mow heavy, wet, or frequent acreage, invest in a genuine Toro 130-0843 belt for better durability and fewer adjustments.
