WHwest8597 85 #1 Posted July 8, 2018 I'm I right in saying these pulleys are on backwards. Small should be on bottom and big on top. Did I damage anything by having them on wrong? It won't let me post pic says to big. Share this post Link to post Share on other sites
953 nut 51,014 #2 Posted July 8, 2018 You didn't mention what model mower it is but didn't matter, the big pulley will be on top and the small pulley is about the size of the other two blade drive pulleys so the blades will all go the same speed. Share this post Link to post Share on other sites

As long as all three blade drive pulleys are the same size you should be correct. Share this post Link to post Share on other sites
