The present application provides a work head for a rotational brush cutter. The work head comprises an upper plate, a lower plate and a blade, the upper plate and the lower plate being fixedly coupled. The lower plate is circular and has a passage therethrough with a gear arranged in the passage. The blade has a body portion and a connection portion with the body portion able to be extended outside of the upper and lower plates. The through passage is designed so that the blade can be replaced without requiring the upper plate and lower plate to be disassembled. As a result, because the blade is not restricted by a narrow space between the upper plate and the main frame, the work head does not need to be removed from the brush cutter to replace the blade thereby saving time and effort. |
