I need a manual for a Montgomery Ward Garden Tractor Signature 2000 Elite Model # 3399006 1465845HO88 Looks like a riding mower to me 18.5/ 40 14 speed transaxle Current problem is the belts turning the blades have loosened. I think one of the springs that kept them tight broke. Not sure of what it looked like or where it needs to be properly placed. Any thoughts on how to proceed? thanks
