I have a CASE 117 that I have had for 10 years or so. About ten years ago I took the mower deck off & I told myself that I would remember how the belts came off. Today I put the deck back on & looked in the 117 owners manual & it only talks about the tractor. I think I have the deck belt right. It goes from both blade pulleys to a idler & a spring loaded tightner up to a drive pulley on the front of the tractor. But I think there is supposed to be another belt from the drive pulley to a idler back to a pulley off of the crank. Does anyone have a 107-118 that they could look & see or a manual that they could post pics of how these belts go. Thanks in advance. Gerald
