Ferris IS 2100Z 61 inch Belt Installation and Belt Routing

The manual isn't great on this belt installation and routing, and I didn't see any other videos that covered the Ferris IS 2100Z 61 inch, so here we are.

It really does help to take the tension off the big tensioner spring when doing this by yourself.
No need to remove any pulleys or tensioners. Just begin on the left side (opposite of discharge) and feed the belt in between the pulleys. One half will be routed around the middle and discharge pulleys, and the other half will around the left pulley, tensioner and idlers back towards the engine.

I find better prices on Ebay than Amazon or other places. Search for "Belt 5103616"
** Stens part number 266-157 **
Keep a spare on hand and you're only down an hour or so replacing the belt.
