Narrative:
We were flying the ILS runway 31 ZZZ; I was PNF and as part of my duties I was making position reports over CTAF (123.0 MHZ). The airport facility personnel were plowing the runway at the time of the first position report. I gave several more position reports. When we were about 600-700 ft AGL; a snow plow reported that he was on the runway. The first officer said 'that's our runway' and called; executed the missed. I communicated our go around and intentions over CTAF and to center (124.2 MHZ). I also asked for vectors to start the approach again. I asked ZZZ facilities to make sure that the runway was clear for our second attempt. The flight continued and terminated without further interruption. After talking with one of the airport facility personnel it turned out that the offending snow plow driver had a malfunctioning radio. ZZZ facility personnel may want to check their radios before commencing operation of their equipment!
