Mike Sullivan

Mike Sullivan is the String Trimmer Specialist at YardToolLab, a role he earned through nearly a decade of hands on lawn care. Before reviewing tools, Mike spent nine years running a residential lawn crew, where he learned that a bad line feed system can ruin an entire afternoon. That real world frustration drove him to test over 80 trimmers and edgers in actual yards, not in a sterile lab. He focuses on battery powered models, line feed reliability, and ergonomics because those details determine whether a tool saves time or causes headaches. Readers can trust Mike’s reviews because they come from the same muddy boots and tangled line he dealt with on the job. He doesn’t chase hype. He reports what holds up under a full day’s work.
