After drawing 3 free body diagrams, but not actually testing, I am thinking that the normal force against the wheels will stop the machine from turning.

This is because of the actions acting against the wheels, vs the wheels acting against the disk.

Good puzzle.

EDIT: Is this a frictionless table?
