Two reasons 1) to protect you from injury 2) to stop the belt jumping off the pulley The latter is more important with manual PTO's than electric clutches.
They really only help keep the belt on if the belt keepers are part of the cover.
Most people remove the covers.
1) for heat
2) because debris collect under the cover and pop the belt off.
Around here the sweet gun balls from sweet gum trees get under the cover and get between the belt and cover.
