I think you are right about one belt. Ours must have been changed to a series of V-belts before we got it. It seems to work fine, and that's the way I thought it was supposed to be, but it looks like it's supposed to have one belt. I had to look it up in a parts breakdown and it is one only, here is a link to a parts diagram for it. http://pdf.germanbliss.com/HL2600SkidSteerLoaderpartsManual.pdf Page 12 parts 16,17,18 show the belt and sheaves (pulleys). I have no idea what that belt may cost but if it's cheaper to go with v-belts, I can assure the will work. At least they have for us, for about 10 years on the same set. The funny thing is about you only doing your own driveway now is now those same folks who never thanked you will probably be complaining your not coming to their house any more. Ha-Ha.
