<p>The portable ground-cultivation tool is moved forwards by hand and has a frame on which a power unit and transmission mechanism are mounted, together with tools and handle-bars. It has two or more oblong tool holders (4,5) coupled to the transmission mechanism (11-17) and with mountings in which cultivating tools (6,7) are gripped, the tool holders performing reciprocating movements in opposite directions. The tool holders can be secured to an arm of the frame, allowing one at least of them to slide in the axial direction.</p> |
