The 18” (455mm) PLUGR is ideal for residential or commercial aeration. No add-on weights are required and reciprocating cam-driven tines propel the unit forward and drive cores up to 2.75” (70mm) deep even in diffucult soil conditions, offering higher quality aeration than traditional drum style units. No-lift turning offers a significant reduction in fatigue while operating and a new ergonomic handle is Iso mounted for reduced vibration. A longer belt span improves belt de-clutching, increasing belt life.
