mower dies when i release the clutch

[chevydog]

I have 13.5 hp craftsman model #917270412 . My son was using the mower and the drive belt broke. I replaced the drive belt, it is on as diagram shows. When the clutch is pushed in ; the belt is loose... when the clutch is let out the belt is tight. The mower will start but dies when I release clutch whether in gear or in neutral. The seat switch is disconnected. If you have any ideas, I would appreciate your input; my grass is growing quickly.

Can you push the mower in neutral with the engine off?
You may have the wrong belt. An inch can make a big difference!

yes, the mower moves freely in neutral.

checked the belt and it is the correct size also

if the mower is engaged the seat switch needs plugged in.
