JoeB 15 #1 Posted October 2, 2018 I have a 312h the speed lever has to be held because unless it is the tractor quickly stops. Is there so adjustment I can make so I don’t have to hold it Share this post Link to post Share on other sites
cleat 5,996 #2 Posted October 2, 2018 This might help. Follow the instructions as per 520 model. Wheel horse 520H service manual.pdf Cleat Share this post Link to post Share on other sites
520hC-120 136 #3 Posted October 2, 2018 Same thing happened with my 520h. Your setup may look similar to the manual Cleat posted. Just tighten the lower bolt to your liking, but not too tight. It will make the lever stay eventually. Share this post Link to post Share on other sites
