Because of their benefits, 4-cycle engines tend to be the more praised of the two.  4-cycle engines are fuel-efficient, quiet, environmentally friendly, and pack more of a punch as they generate power through torque instead of RPMs.  They’re so eco-friendly that some states even require landscapers to use only 4-stroke trimmers for their limited impact on the environment.  2-stroke engines, however, are cheaper, more lightweight, and are easier to store and maintain. These engines work on fewer parts and offer less vibration, which can help lower fatigue.  Most of the brush cutters on our list run on a 2-cycle engine, and for small residential properties, staying within your budget and saving on storage may be more appealing.
