An older Kees 48" Beltdrive with a 14hp Kawi. I picked it up cheap for my brother to mow his property. I have been able to use other brands for many parts, blades, belts, a spindle as there are no dealers and I think the line was bought out. I am looking for the COMPRESSION springs that are used to keep tension on the drivebelts and the levers. They have weakened and no longer provide tension to keep the belts from slipping. Can anyone help me out with these?
