The pilot's failure to observe the runway environment while operating in the traffic pattern and his subsequent failure to maintain clearance from a lawnmower on the runway during the landing roll. Contributing to the accident was the lawnmower operator's decision to remain on the runway while troubleshooting the mowing equipment without monitoring the airport's common traffic advisory frequency.
