Narrative:

When 12 miles out I began announcing my intentions to land and 5 miles out the same and while on 3 mile final still announcing my intentions and asked if there were any aircraft in pattern. There were other aircraft using the frequency but I got no specific responses to my request for any aircraft in the pattern (possibly radios transmissions were stepped on). I then noticed a tow plane taking off on the parallel grass runway. It was towing a glider.I then made several calls asking the tow plane's intention after takeoff to assure he would not turn over the paved runway I was on final for. I got no response each time (transmissions could have been stepped on). While on final I was using checklist; put down gear and flaps to land; I then landed; the gear was up. During the final I was not looking a gear lights as they are behind the yoke on the A-36; so I did not notice they were not down. As I was distracted watching and calling the glider tow plane I missed seeing the lights were not down; also the gear warning horn did not activate! This was the first flight after the annual. So when my gear warning horn did not sound I had no idea my gear was still up.after the incident and my plane was towed to the hangar; I hired a mechanic to check the gear warning system horn by placing the plane on jacks and following the beechcraft check list for the annual. The horn did not come on as required when the throttle was reduced and the gear was up. So when I heard no horn I believed my gear was down.preventions could have been to have looked at mirror to verify gear down; or lights were green; but in the events of trying to verify the tow planes intentions it was not done.
