Stens 265-546 Belt Replaces Toro 6738 86-1/8-Inch by-1/2-inch

What It Is

This is a replacement drive belt for Toro TimeCutter and other zero-turn mowers, specifically designed to transfer power from the engine to the cutting deck. It measures 86-1/8 inches in length by 1/2-inch width, fitting decks in the 42- to 54-inch range.

Fitment & Compatibility

Before buying, check your mower’s deck size and model number. This Stens 265-546 belt replaces OEM Toro part 6738 and is compatible with Toro TimeCutter SS4225, SS5000, Z4200, Z5000, Z5400, and Z5500 (and some Exmark models). Verify your deck’s belt routing diagram (often printed on deck or in manual) to confirm length—86-1/8 inches. It’s an aftermarket alternative to Toro’s OEM belt, so expect similar performance at a lower price.

Key Things to Know

• Quality: Stens belts are known for good durability in residential use, but may wear slightly faster than OEM under heavy commercial cutting.
• Installation: Moderate difficulty—requires removing deck and belt tensioner. Have a diagram or video handy; routing mistakes cause poor cutting or belt damage.
• Common gotcha: Check your old belt’s length—if it’s stretched or broken, measure a straight section. A 1/2-inch difference can cause slipping or damage.
• Lubrication: No belt dressing needed. Keep pulleys clean and free of debris for longest life.

Should You Buy It

If you own a compatible Toro TimeCutter or similar zero-turn and want a reliable, budget-friendly replacement for the OEM belt (often $10–$15 more), this is a solid choice. It’s best for homeowners or light commercial users who don’t need a heavy-duty commercial belt. If you mow daily in tough conditions, consider a premium brand like OEM or Gates.
