What It Is

This is a 1/2-inch wide by 112-inch long replacement deck belt designed for select Toro TimeCutter and LawnBoy zero-turn mowers. It drives the mower blades via the deck spindle pulleys.

Fitment & Compatibility

Before buying, verify your mower’s model number—not just the series name. This belt fits Toro TimeCutter Z4200 (74360), Z4235, Z4202, Z4220 (74380, 74381, 74363, 74365, 74366) and LawnBoy 81270 and Z3400HLX. Cross-reference with OEM part number 110-6871. Measure your old belt: it must be exactly 112 inches long and 1/2 inch wide. This belt is not for Z4200 models with 50-inch or 60-inch decks—only those with a 42-inch deck. Check your deck size (stamped on the deck or in the manual) before ordering.

Key Things to Know

• Quality: Aftermarket belt; some users report shorter life than OEM, but it’s fine for light-to-moderate residential use.
• Installation: Moderate difficulty. You’ll need to remove the deck or at least the belt cover, and route the belt around all pulleys per the diagram (usually on the deck or in the manual). A belt tensioner tool may be required.
• Gotcha: Double-check the belt routing—if you miss a pulley, the blades won’t engage or the belt will slip off. Also, inspect pulleys for wear; a worn pulley can damage a new belt quickly.
• Price: At $14.99, it’s about half the cost of OEM, making it a budget-friendly option.

Should You Buy It

Buy this if you need a quick, affordable replacement for a 42-inch deck Toro TimeCutter or compatible LawnBoy zero-turn and you’re comfortable with DIY installation. Skip it if you want OEM-grade longevity or have a larger deck size—verify your model and deck size first to avoid returns.
