Powerflo: help with belt routing

[snpower]

I've inherited a powerflo system from my father's GT275; the manual is nowhere to be found and I can't get the belt tight enough to use with the tractor. I was hoping someone could share the belt routing diagram if possible? It's the 48 and 54 mow system, bought around 1998. TIA.

Should be correct if it is twisted such that the power flow blower turns in the right direction.

Or, post a pic.
