Felix 145 #1 Posted May 16, 2019 What size drive belt do I need to order for a b80 4 speed. I’ve got the old belt of and it looks like it is about 81 inches. Does this sound about right? I’m in the uk so if anyone knows of a supplier over here that would be a real help. 👍🏻 Share this post Link to post Share on other sites

ET160 30 #3 Posted May 16, 2019 I have the same model and had a difficult time finding a belt that would work. 82" was too short and would grind going into gear; 83" was too long and was jerky reengaging. I found a 82.5" belt for a Scag mower that worked. 1 Share this post Link to post Share on other sites
