Liberty work shop 9 #1 Posted June 5, 2022 Hi all . I'm Liberty Work Shop and I've been rebuilding and restoring garden tractors for many years . Have a question .I just watched a video on you tube where the guy installed a toro single stage snow thrower on a 520H and my question is this , does that blower have a reversing gearbox on it , or how does it turn the right way ? The engine turns CCW looking at the PTO and the thrower shaft has to turn CW , looking at it from the same side . Or am I just missing something ? Any help would be welcome ... Thanks 1 Share this post Link to post Share on other sites

Liberty work shop 9 #4 Posted June 5, 2022 Ok . Cool , it's all clear to me now , L O L . I figured the direction change was done with the drive belt somehow . I am getting ready to reconfigure a Bolens single stage for my 520H ...Now I know what I need to do to effect the rotation change . Thanks very much . 1 Share this post Link to post Share on other sites

This is one of the cleverer bits of engineering I've seen and wondered what inspired it. I've since seen an early chain drive for a "motor car" that used three chains continuously engaged -- two for forward speeds and one with idlers that gave them reverse. No gearbox. A slider on the "drive" shaft engaged one drive sprocket at a time. I'm thinking it was bicycle mechanics that dreamed it up! Share this post Link to post Share on other sites
Liberty work shop 9 #6 Posted June 6, 2022 Yes ... Someone certainly had their thinking cap on when they came up with this ... So simple yet .......... 1 Share this post Link to post Share on other sites
