Kevvc203 0 #1 Posted January 5, 2018 I have a 257-H with a snow blower attached, i keep throwing the belt and cant seem to be able to tighten it. Does anyone have a proper belt diagram and tension tip? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,440 #2 Posted January 5, 2018 We do not have a manual for this one. The parts list shows 2 idlers at the rear that are adjustable for the belt tension. Looks like one is set for partial tension and the second has a spring loaded bolt to obtain the final tension. Garry Share this post Link to post Share on other sites
