Hey Steve, found this thread and it has a parts breakdown of the Didier. It's a manual for a JD, but it may help you out some. Half way down the page is a few pages of the manual and from what I could see there are 2 v-belts, #36---v-belt A-82, #39---v-belt A-100. Don't know if those #'s will help, good luck buddy http://www.weekendfreedommachines.co...335/85922.html
