摘要： A compact, lightweight and easy-to-use wheeled lawn care unit comprising a two-wheeled carriage, a power source, plurality of tools which may be alternatively connected to the power source, a handle and a boom connecting the selected tool to the power source. The power source is pivotally connected to the carriage at a location within its footprint. The unit has a low center of gravity by placing the power source pivot and center of gravity within a cylinder defined by the wheels. The boom extends horizontally from the power source and is of a split boom configuration which allows selective rotation for the boom portions relative to one another. An edger can be selected for the unit, which includes a spring-loaded wheel. The edger may be rotated from a non-working position where the edger blade does not contact the ground to a working position by rocking a handle behind the carriage forward against the bias of the spring. A second more compact version has the shield positioned on the boom.
