Mike in Mankato MN mower is an 1999 yardman 604 series with the 16 hp Kohlar motor.....and of course it is having transaxle problems. I AM ABOUT READY TO GO BACK TO MY WONDERFUL SNAPPER. LOL I am looking forward to searching this site
Welcome mwilen, good to have you here with us, and sorry to hear of the issues with your Yardman, best wishes in finding a resolution to the problem with the transaxle. If it has the K46 Tuff Torq, there are fixes for it, check the JD forum stickies, been through that myself .
