I got this 30" Craftsman 13.5hp Hydrostatic transmission that needs a new motion drive belt. I've got the new belt and I looked in the owner's guide on to change it and it looks pretty involved. Has anyone here done it and know of any shortcuts that work? It says I got to raise it up take both rear wheels off and loosen the transmission and also remove the entire deck. What kinda time should it take? Is there going to be a lot of playing with adjustments after installing or is it pretty much done when you replace it?
