Hi all: I have a 48" Ransomes Bobcat walk behind and the "PTO" belt comes off the blade idler pulley and then shreds to pieces. I've attached 3 pics to show what I believe is the issue. 1st pic shows pulley and belt layout. 2nd pic shows what happens to the belt after disengaging the blades. When I reengage the belt gets caught under the blade idler pulley and it's toast. 3rd pic shows how the belt lays from the engine shaft PTO pulley to the blade idler pulley. The PTO pulley on the engine shaft seems to be quite a bit lower. The only possible adjustment I can see is what might be a spacer above the PTO pulley...between it and the pulley for the trans/wheels. Does anyone have any idea how to remedy? Thanks!
