Make sure the engine is off, and then look under the tractor at the electric PTO clutch. You should see a pigtail going to it that supplies power. Make sure that pigtail is plugged into the tractor harness. This will be on the right side of the tractor. If that plug is not secure the clutch may not be getting power to it.
If you sit on the seat with the clutch/brake pushed down and turn the key on (do not start engine), you can pull out on the PTO switch and you should hear the PTO clutch engage and make a "clank" sound. If you do not hear that it may be due to a problem with power coming from the switch.
If the machine is new you may want to contact
Sears Home Services
and have a tech come out to take care of this.
