Does anyone know how I could tell if the transmission belt is slipping on a small commercial mower?

Question

The instruction manual says to check it once a year and to tighten or replace it.

how is a simple way to tell if the transmission belt is slipping or not.

dont want to waste my time with meaningless things, but I dont want to damage my mower either.

Thanks for your answers!
