Belt smell

Howdy all! ..Had my Gator about 3 months now (825i). Haven't had time to enjoy as much as I want yet but got about 35 miles on it and today for the first time I smelled what seems to some belt slip. No smoke just odor and had been driving around a field about at 8 mph for 20 minutes. My question is this normal to smell this during break in?
THANKS in advance...
