Narrative:

Just after starting my takeoff roll; I passed a snow plow on my right side at about a high taxi speed. I throttled back until I was by him then continued. He was on the edge of the runway. I announced my intentions several times on the CTAF to later find out myself that I was on another transmitter. Just prior to arriving at the airport I called the FSS and asked for NOTAMS at the airport. Nothing was said about snow removal operations. I taxied more than halfway down the runway to make sure it was all clear. I did a 180 and taxied back to the beginning of the runway and started my takeoff roll and within seconds saw the plow. There wasn't any danger of a collision but it surprised us both. I messed up by not ensuring that I was using the correct transmitter when announcing my intentions.

Original NASA ASRS Text

Title: BE55 PLT INITIATED TKOF ROLL AND DISCOVERED A SNOW PLOW OPERATING ALONG THE SIDE OF THE RWY.

Narrative: JUST AFTER STARTING MY TAKEOFF ROLL; I PASSED A SNOW PLOW ON MY R SIDE AT ABOUT A HIGH TAXI SPEED. I THROTTLED BACK UNTIL I WAS BY HIM THEN CONTINUED. HE WAS ON THE EDGE OF THE RWY. I ANNOUNCED MY INTENTIONS SEVERAL TIMES ON THE CTAF TO LATER FIND OUT MYSELF THAT I WAS ON ANOTHER TRANSMITTER. JUST PRIOR TO ARRIVING AT THE ARPT I CALLED THE FSS AND ASKED FOR NOTAMS AT THE ARPT. NOTHING WAS SAID ABOUT SNOW REMOVAL OPS. I TAXIED MORE THAN HALFWAY DOWN THE RWY TO MAKE SURE IT WAS ALL CLR. I DID A 180 AND TAXIED BACK TO THE BEGINNING OF THE RWY AND STARTED MY TAKEOFF ROLL AND WITHIN SECONDS SAW THE PLOW. THERE WASN'T ANY DANGER OF A COLLISION BUT IT SURPRISED US BOTH. I MESSED UP BY NOT ENSURING THAT I WAS USING THE CORRECT TRANSMITTER WHEN ANNOUNCING MY INTENTIONS.
