Not familiar with that particular mower, but if it’s like any other drum mower I’ve worked on, the first place to look would be the gears in the top, above the drums.

Take the guards off and all the bolts holding the gearbox cover and you should see what’s going on, if you do need to take a drum shaft out, you’ll need this off anyway.

Probably the gear on the shaft stripped its teeth or sheared the key, on either the horizontal or the vertical
As above, remove cover, open the trough & have a look, pretty simple machines.

As @balerman replied, yes.
Depending on which one has stripped/sheared.
All will be revealed when you take the lid off the trough/oil bath
There is a horizontal shaft with angled gears meshed to the vertical shafts in an oil bath ( the trough) - all fairly straight forward.
FWIW I have seen them where the teeth have worn & engagement has been sporadic resulting in 1 drum spinning at full speed while the other intermittently loses drive & momentum - the resultant cut looking like a bad haircut.
Be aware there are various shims involved in the set up - photograph everything as you go.
