I just took it to the shop and the guy told me he looked everywhere for a belt and couldn't find one. I might need to go pick up a belt gauge and try and see what the measurements are for it.
Otherwise I am having trouble even finding belts for the black rock and landscaper supply mowers. Those brands do sound familiar though when I looked awhile back so i think that is the right track. Its a good mower but I wish it was easier to find a belt for it!
