Overview
This aftermarket deck drive belt is a direct replacement for Toro OEM part number 119-8819 (also cross-referenced as 147-2924 and 147-2924-SL). It is engineered for 42-inch TimeCutter zero-turn mowers and transfers power from the engine pulley to the mower deck spindles.

Common questions
Q: Will this 1/2-in x 113-in belt fit my Toro 75742 42-in zero-turn, and does it replace part number 119-8819?
Yes, this belt is made to fit Toro 42-inch zero-turn models including 75742, and it is designed as a replacement for OEM belt number 119-8819. It is also listed for models 75747, 75744, 75745, 75740, and 75741, so match your mower model and belt number before installing.
Q: Is this the deck belt or the drive belt for a Toro 75745, and how can I confirm I’m ordering the right one?
This replacement is listed as a deck/drive belt for compatible 42-inch Toro zero-turn models such as the 75745, with a belt size of 1/2 inch by 113 inches. The best way to confirm is to check your mower’s model tag and compare the old belt’s part number or routing diagram to OEM replacement 119-8819.
Q: Do I need any special steps to install this belt on a Toro 75741, and how can I make it last longer?
When installing it on a 75741, make sure the mower is off, the key is removed, and the belt is routed exactly as shown on the mower’s belt diagram so it sits fully in each pulley groove. To extend belt life, keep the pulleys and deck area clean, check idlers for rough bearings or wobble, and make sure the belt tension system moves freely without binding.
