daveoman1966 3,839 #2 Posted February 27, 2014 If your model is 1-0370 (1973 8hp manuial trans) your belt should be OEM # 7473. If you don't use the OEM belt, it will soon fail. OEM new is about $30 from Toro dealers. Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,482 #4 Posted February 28, 2014 The 8 on the end is not used but it tells us it is a 1973 model. 8-5=3=1973 The 1-0120 is a 8hp 4-speed The 1-0370 is a 8hp 8-speed Both use the 7473 Toro belt. Garry Share this post Link to post Share on other sites
