This genuine Toro OEM 103.50-inch replacement V-belt is manufactured to exact engineering specifications for reliable power transfer in your Toro equipment. At 103.50 inches this is a long-span belt used in larger deck or wide-area drive configurations — the precise length and cross-section profile are critical for correct tension and pulley seating at this span length. Aftermarket alternatives at this length are particularly prone to stretch and incorrect fit. Verify your model and serial number before ordering to confirm this is the correct belt for your equipment.
