Thank you so much for that diagram! I did have the belt on incorrectly and it runs great now! Thank you so much for your help Eugene!
The bypass for the transaxles are set to the correct position for driving.
I double checked the idler pulley and it is spinning, the belt is moving and it is on all the pulleys pretty snug. Everything operates normally otherwise, but it still won't move forward or reverse. Is there a diagram showing the way the drive belt should be ran through the pulleys just incase I ran it incorrectly? All I can ever find is diagrams for the deck belt. If the belt happens to be on correctly and since all the pulleys are working, is there anything else I should check for?
Thanks
