Check under the deck and make sure the blades can spin freely, there will be resistance but mostly check to see if they are stuck. If they are not and can move, you can try to remove the belt from the pto, engage and see if it spins then. If it does not than there is probably an issue with pto clutch

you've routed the belt incorrectly.

look at the fuses there maybe a blown one

check for power at the clutch if no power check the safety switches and the switch itself

Hi,

The safety switch beneath the seat is only one part of the several interconnecting safety features of the modern riding mower. If the system works properly, you must be seated for the mower deck to operate. The tractor will continue running with the Power Take Off disengaged if the parking brake is set before the operator leaves the seat.The seat switch consists of two electrical contacts normally separated by an air gap. A spring creates an open space between the two contacts. Mounted between two plates, the switch's spring compresses under the weight of the person sitting in the operator seat and completes an electrical circuit. With the switch closed the tractor's ignition system can be switched on with the ignition key. If the operator stands, the spring forces the gap open and interrupts the electrical ignition circuit. The safety circuit allows the riding mower motor to continue running if the PTO is not engaged. When the parking brake is set a second switch in electrical parallel with the OPS closes. This bypasses the safety switch under the seat. If the operator stands, the parking brake switch still completes the ignition circuit.The mower blade turns only when the PTO engages. If the operator should leave the seat with the blade turning and under power, injuries could result. The mower blade would even continue spinning at full power if the machine overturned. To prevent this type of accident, engaging the PTO deactivates a connection in the original circuit and completes a second circuit in series with the OPS switch.

If the operator leaves the seat with the PTO engaged, the ignition interrupts and the machine stops. Until the PTO is off, no combination of settings will restart the mower.

Using a test light or volt meter, check to see if you are getting a full 12 volts at the connector where the PTO plugs in. If no voltage present, locate the fuse for the PTO and check it, also check the PTO switch to see if it is working. You can turn on the ignition switch to the run position, don't start the engine, and turn the PTO switch on and off several times listening for a clicking sound. If you hear it clicking, have someone sit in the seat and start up the engine, while it is running, observe the PTO clutch and see if it spins when turned on and if the belt turns with it. If none of this works, post a follow up and include your Craftsman Model number. I will look it up and see if I can find anything else we might be missing

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.

Hello janec37415:

>>From your Description it Sounds like the Seat Safety Switch is Bad, has a Bad Connection or the Stator/Charging Coils are Not Charging Enough for the PTO to be Engaged.
>>When the Blade is Engaged, the Seat Switch is Showing No One is on the Seat so the Engine is Shut Off by the Safety System or
>>When the PTO is Engaged and the Stator/Charging Coils are Not Charging Correctly, the Carburetor Solenoid Does Not get enough Voltage to Stay Open and the Engine Quits.
>>If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy.
>>Thanks.
