What It Is

The 105-8783 is a 60-inch deck drive belt for Toro Z Master zero-turn mowers, connecting the engine pulley to the deck spindles to spin the blades. It’s built with aramid cord reinforcement for heavy-duty commercial or residential mowing on 60-inch cutting decks.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This belt fits Toro Z Master models including 74262TE, 74249, 74262CP, 74255, 74251, 74250, 74246, 74246TE, 74245, 74244, 74238, 74238CP, 74272, 74272CP, and Z500/Z555 series with a 60-inch deck. It measures 5/8 inch wide by 242 inches long—measure your old belt’s length and width to verify. This is an aftermarket replacement for OEM part 105-8783; check that your mower uses a single belt for the deck (not a two-belt system). If your model uses a different belt length or width (e.g., 1/2 inch), this won’t fit.

Key Things to Know

• Quality: Aramid cord construction is stronger than standard rubber belts, offering better heat resistance and longer life in heavy-use commercial mowing.
• Installation: Moderate difficulty—requires removing the deck or accessing pulleys. Follow your mower’s belt routing diagram; incorrect routing causes poor blade engagement or belt slip.
• Common gotcha: This belt is for the deck drive only, not the pump/hydro drive. Do not substitute it for a drive belt.
• Fit note: Some users report it runs slightly tight on older machines; check pulley alignment and tension before finalizing installation.

Should You Buy It

Buy this if you own one of the listed Toro Z Master models with a 60-inch deck and need a durable, cost-effective replacement for the OEM belt. It’s ideal for commercial landscapers or heavy residential users who want aramid cord strength over standard belts. Avoid if your mower uses a different belt size or if you’re replacing a pump drive belt.
