Narrative:

Landing was made with snow removal equipment in the arrival area of runway. Unable to communicate to snow removal personnel due to the pilot not putting the correct CTAF frequency in his radio.there were no notams obtained indicating that there was going to be snow removal equipment working at the time of arrival.the incorrect frequency of 122.8 was put in the number 2 radio; the correct frequency was 122.7. A contributing actor was the stress of a long work day due to weather.there was an airline flight inbound and made me feel rushed to get on the ground and cancel IFR so they could start the approach. After cleared for the approach I made multiple radio calls on the incorrect frequency inbound to the airport.upon breaking out of the clouds the approach lights appeared to be on high setting and the approach was continued on visual from about a 1.25 miles out. About 0.5 miles from the runway I saw yellow vehicle beacons and headlights near the arrival end of the runway. I continued the approach to landing even though the vehicles looked like they where closer than the hold short line. I did decide to land long not knowing the how close the vehicles where to the runway and not seeing any other vehicle lights the rest of the length of runway. There was confrontation with a worker claiming that I had almost landed on them. Upon the discussion it was found that I had put the incorrect frequency in the radio.in my review of the events I am trying to make sure that CTAF frequencies are briefed properly. Also a discussion over the length of day has occurred and discussed ways to reduce the stress of a long work day due to weather.
