Installation of drive belt on older john deere LT 166 with mulching deck

Hi,
There are two Freedom 42 decks that use different belts and route them very differently. You can take the link in my sig to opebycrigby.com or click on crigby and take the website choice in the drop down menu to see multiple views of both decks. There are directions for one deck at JDAnswers.
Checked and I have not posted the update yet so navigation leaves something to be desired. Try this link:

Peace,
