20 Best 4 Cycle String Trimmer (2022 Updated)

A 4 cycle string trimmer is a type of lawn care tool that uses a four stroke engine to power a cutting line. This type of trimmer is typically more powerful and efficient than a 2 cycle model, and is often used by professional landscapers and gardeners.

While they may be more expensive upfront, 4 cycle trimmers typically require less maintenance and are more durable, making them a good investment for those who use them frequently.
