The machine consists of two primary parts connected by a flexible shaft and a long main drive pole:The Backpack Power Unit: Features a small gasoline engine (typically a 2-stroke or 4-stroke engine ranging from 35cc to 52cc) mounted on a padded backpack frame. This ergonomic design transfers the engine weight to the operator's back, reducing fatigue during extended field use.The Cultivator/Weeder Attachment: Equipped with rotating metal weeding wheels (or rotary tines). These blades are engineered to cultivate loose soil, remove weeds, break up compacted ground, and aerate soil beds efficiently.
