According to the search results, Radar left MAS*H during season 8 because Gary Burghoff, the actor who played Radar, was burned out by the shows schedule and being away from his family for long periods. In the series itself, Radars exit was explained as being given a hardship discharge so he could go back to his family farm and help his mother following his uncles death. Fellow cast member Mike Farrell tried to persuade Burghoff to stay on the show, but he decided to leave. Burghoff returned the following year to record a special two-part goodbye episode called "Goodbye Radar". The characters exit was emotional and well-received by fans, and the show continued without him. Burghoffs brief appearances on the failed sitcom "AfterMASH" showed that Radar still lived on his family farm, but the spinoff was not successful.
