Small Engines (Lawn Mowers, etc.): model 68 belt, john deere model, pulley


Question
i am almost finished working on a john deere model 68.  arrived in pieces and i don't know the the proper way to route the deck belt.  can you help me with this please?

Answer
I can't find a picture any where.

Here is the rule on belts in general.  These are the rules that I use to install belts when I don't have a diagram.

Flats on backs, v's on v's.

What that means is if the idler or pulley is flat it engages against the flat side, or back, of the belt.  If its a V shaped pulley it will have the v of the belt running against it.

Using this principle the "68" will be easy.  Flip the deck lever while looking under the mower.  Watch which way the "flat" idler moves.  Then use the "flats on backs, v's on v's rule.  It will be common sense.
