orangejr 0 Posted July 13, 2014 Wondering if anyone can point me to the correct belt to drive the 42" mower deck on a Baron-S 3414S (circa 1974). It's one of my dad's old toys...same deck fit on his 716 from the same era. I've been through the 3414S tractor manual, and if the belt spec is in there I missed it. I haven't found documentation for the deck itself yet...any advice appreciated. Share this post Link to post Share on other sites
MikeES 484 Posted July 14, 2014 The PTO to deck belt is a 4L740 and the deck arbor belt is a 4L820. Share this post Link to post Share on other sites
