While performing an ILS approach to the hayden airport on an IFR flight plan, after reporting procedure turn inbound to den center and hayden (yampa valley) unicom, upon breaking out of the low overcast at approximately 400' and 1/2 mi visibility. I observed and had to fly over a snow plow truck on the runway at the T/D end of the active. There was no NOTAM. After inquiry, I was told that the trucks are not equipped to monitor unicom. Fortunately the truck was not moving in my same direction. A missed approach was not desirable.
