cafoose 3,393 #1 Posted May 21, 2024 (edited) Does anybody know the diameter of the 953 engine drive pulley part number 3594? I'm trying to figure out the correct speed to drive my SMS-50 sickle bar. The driven pulley below the engine is 4 5/8" diameter. The drive pulley on the PTO I was going to use is 3 1/4". @gwest_ca @953 nut Edited May 21, 2024 by cafoose Share this post Link to post Share on other sites
953 nut 58,332 #2 Posted May 21, 2024 Here are some photos of the engine drive pulley with measurements. The smaller "V" pulley takes a 3L belt and probably wouldn't be a good choice for driving the mower. Share this post Link to post Share on other sites
