I need a belt diagram for a 170 john deere 38" deck

Remember the belt rule, V of the belt goes in V pulleys.Flat pulleys that are stationary or move get the back of the belt. You can figure it out. Its not rocket science. Remember at some point there has to be a tensioner,usually gets the back of the belt if its a flat pulley. U may have to remove the spring and then reattach the spring after the belt is routed.

Ok Simple Rule
V BELTS go in V pulleys
Flat pulleys get the back of the belt. You must take the deck off the tractor to do this properly. Look inside the hood I have seen belt diagrams there or on top of the deck.
When all else fails Go to the JD Dealer they will gladly help.
