There are multiple options of 3M work tunes, one that is just AM/FM, one that is just bluetooth capable and one that has both. I have seen prices for these from around $50-100 depending on which features you want. Another option is to simply use a bluetooth speaker strapped to your mower. You can stream from your phone or you could even find one with radio. The battery life on these speakers is quite good these days with upwards of 24 hours of playback on a charge.
