Robyn, sounds like the belt may have been installed wrong, check your manuals belt routing.

if you dont use kevlar belts,then you are wasting money,they cost more,but,they last ten times longer,use the widest width that it can handle,dont buy from jd,it will cost you 100.00,go to ebay,etc,your tensioner should not be tight enoughto stretch the belt also,here is a jd belt,you can get cheaper just make sure it looks green or red,not rubber black, JOHN DEERE oem Mule Drive Belt TCU13195 737 757 Trak below 030000

check your idler pulleys. ipl indicates there 3 each and one different depending your serial.

Park brake switch is the most likely culprit,any other would cause the tractor to not turn over in the crank position.

check tensioner

Check both belts on deck. Check if the clutch is clicking in. If not it will most likely need a new pto switch.
