Reddit reviews Browning AX42 Gripnotch Belt, AX Belt Section, 43.3 Pitch Length

If you're trying to save money (or you don't like the whine of a link belt) I'd recommend a cogged v-belt instead. The length you need may vary based on your motor and setup. Some others recommended just using a regular v-belt and just removing the tension when not using the saw, but the cogged belt is quite inexpensive, doesn't whine (like the link belt), improves power transmission efficiency a little bit vs. the regular v-belt, and solves the vibration problem without needing tension removed the way a normal v-belt would.
