SIUC3 9 #1 Posted March 27, 2018 I have done some research and I just want to double check I will be getting the correct belt sizes for my 856. I need to replace all the belts (Trans Belt) (1st Mower Drive Belt) (2nd Mower Deck Drive belt pair) 1st Mower Drive Belt is - Toro 7430 Replaces 1577 (4L x 28") 1/2" x 28" 2nd Mower Drive Belt (pair) - Toro 1578 (3L x 37") 3/8" x 37" Trans belt - I couldn't find this one, but from the original parts list it is listed as 1576? Any info or help is greatly appreciated! Thanks, Scott Share this post Link to post Share on other sites
