How do I install a drive belt on my 42" Craftsman lawn tractor. The belt is for the mower blades to turn. I have instruction on how to install it but I'm having difficulties getting the belt on the last pully. What the secret?

Here is my generic answer for replacing a belt on any brand deck. https://www.askmehelpdesk.com/tools-...lt-252705.html Try it, hope it helps and write back with any other question. The last pulley really requires the spring tensioned idler pulley to be retracted all the way.
