My Poulan 13.5 hp runs until cluch is released

Sounds like the clutch plates may be stuck together. Happened to me after a long trip in the rain and bike sat for a few weeks after that. Had to take the cluch discs out and clean them

Check to see if the clutch cable is broken. Watch the long clutch release lever under the oil tank as you squeeze the clutch lever. If it doesn't move when you squeeze the lever, your cable is broken. If it does, you've got problems with the release mechanism inside the right side of your transmission most likely.

I have same ride same problem put your ear down by the cluch lever and you will hear a click when you let the cluch out the same time the radio quits if you take the switch off and hold it closed the radio will work all the time

the only adjustment is on the clutch lever, it has 4 positions with numbers 1 is most contact less travel and 4 is less travel to release

The chuck may just be sticking. Remove the front housing with the large screw, tap the chuck with a hammer & pin, and lube.

sounds like belt is to tight or the electric clutch isn't disengaging

Mate I had this problem, it was the compression, had to get new piston and rings. good luck.

There is a seat safety switch located beneath most seats, and on some models one on the PTO lever. Depending on the model, there will also be one on the foward reverse tranmission lever if equipped.

you mght check to see if the belt has jumped off

There is an operator presence switch under the seat...it is more than likely faulty and must be replaced in order for the mower to run right.
