I've got a 117 that I've owned for ten years or so. I took the mower deck off tens years ago & I remember telling myself OH I"LL REMEMBER HOW THE BELTS GO BACK ON. Well guess what. I looked in my tractor owners manual & it only talks about the tractor & not the deck belt routing. I think I have the deck belt on correctly It goes from the two blade pulleys to a idler & a tightner then up to a drive on the front of the tractor. But I think there is another belt that goes from that drive to another idler & then to a pulley on the crankshaft. Does anyone have a 107-118 that could look for me or have a manual that could post a pic. for me. I would really appreciate it. Thanks in advance. Gerald
