Pause for a second and consider what usually keeps some part of a tranny stationary. It's usually metal. If the wheels are stalled, the sun is under torque. In fact, you should be able to figure that torque out pretty easily. Work your CIM stall torque forward to the axle, and then backward to the sun. Assuming your power takeoff is on the planet holder, the ratio should be (Outer ring/CIM pinion)*(Sun/Inner Ring) * CIM Stall * 2. I have a feeling the first bit is going to be around 1. Possibly greater than one. So you're looking at twice the CIM stall torque being applied to your ND drive shaft. Plus, even worse, shock loads. I'd actually be very worried about this, really.
