Deck Belt 1/2" X 112" Compatible with Toro 42 Inch Z4235 Z4200 Z4202 TimeCutter RZT420H Zero Turn Mowers 110-6871

What It Is

This is a replacement deck drive belt (1/2" wide, 112" long) for Toro Z4235, Z4200, Z4202, and TimeCutter RZT420H zero-turn mowers with 42-inch decks. It transfers power from the engine pulley to the blade spindles.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 42 inches and the belt length measures 112 inches (measure your old belt end-to-end, not around pulleys). This belt replaces OEM Toro part 110-6871. It is not compatible with 44-inch or 50-inch decks, or with standard push mowers. Check your mower’s model number (e.g., Z4235, Z4200) on the frame or under the seat—this belt fits those specific TimeCutter and RZT models only.

Key Things to Know

• Quality: Aftermarket belt; most users report good durability, but OEM belts may last slightly longer under heavy use.
• Installation: Moderate difficulty. You’ll need to remove the deck, release tension from the spring-loaded idler pulley, and route the belt per the deck diagram (take a photo before removal).
• Common gotcha: The belt must be seated correctly in all pulley grooves—mis-routing causes blade slipping or belt snapping on startup.
• Check pulleys: Inspect for debris, rust, or worn bearings before installing a new belt; a seized pulley will shred the belt quickly.

Should You Buy It

If you own a Toro 42-inch Z4235, Z4200, Z4202, or TimeCutter RZT420H and need a reliable, budget-friendly replacement for routine belt wear, this is a solid choice. It’s not for heavy commercial use or non-Toro decks, but for homeowners and light-duty mowing, it delivers good value at half the OEM price.
