Lawn Mower Tractor Cogged Pump Drive Belt Fits Toro 110-6774 Timecutter Z4200 Z4220 Z4235 Z5000 Z5020 (1/2" x62 1/2")

What It Is

This is a cogged (toothed) pump drive belt for Toro Timecutter zero-turn mowers. It transfers power from the engine to the hydraulic pump, enabling forward/reverse motion. Designed specifically for Z4200, Z4220, Z4235, Z5000, and Z5020 models.

Fitment & Compatibility

Before buying, confirm your mower’s exact model number (stamped under seat or on frame). This belt fits Toro OEM part 110-6774. It measures 1/2” wide x 62 1/2” long (end-to-end). The “cogged” design is critical – a smooth belt will slip. Does NOT fit Z4000, Z4500, or Z5300 series. Deck size (44”, 50”, 60”) doesn’t matter for this belt – it’s pump-only.

Key Things to Know

• Quality variance: Aftermarket belts may wear faster than OEM. Check reviews for premature cracking. This one is rated 4.2 stars – acceptable for the price.
• Installation difficulty: Moderate. You’ll need to remove the deck and possibly the right-side fender panel. A belt tensioner tool (or a long wrench) is required.
• Common gotcha: The belt routing must match the diagram exactly – wrong wrap around the pump pulley will cause slipping or noise. Take a photo before removal.
• Length tolerance: 62.5” is exact – a belt 1” longer won’t tension properly. Measure your old belt if possible.

Should You Buy It

Buy this if you need a quick, budget-friendly replacement for a worn or broken pump drive belt on a compatible Toro Timecutter. It’s not OEM quality, but for $12.99 it’s a solid temporary fix or spare. Skip it if you want maximum durability for heavy commercial use – stick with the genuine Toro belt (about $30).
