This research article assesses the efficacy of autonomous mowers on St. Augustinegrass lawns compared to conventional mowers. The study found that autonomous mowers, despite using a lower cutting height, resulted in superior turfgrass quality, particularly during winter months, and better uniformity. While autonomous mowers showed increased efficiency in some aspects, the study also notes potential drawbacks such as wear patterns and the need for preventative pest control near charging stations. Further research is suggested to explore the impact on weed control, fertilizer needs, and other turf management practices. The findings highlight the potential of autonomous mowers for sustainable lawn care, but also point to areas needing further investigation
