Equipment buying scam

I am selling a windrow compost turner on my little salesmen site. I received a text on a person interested and agreed on price. He took my information so that he could send a cashiers check and the amount was 5k over price when planning trucking for pickup the buyer wanted us to wire the 5k back to him to set up trucking. All conversations were through text only already red flags person did not want to talk in person. Once check arrived, he asks if we deposited it yet when i said yes, he was pushy on returning the 5 k to pay for trucking a week later check came back as fraudulent a day before we got notified by bank i told him were not sending anything until we speak on phone never heard from him again.
