Furthermore, it is characterized by further comprising a pressing spring for pressing the gear case against the support.

According to the present invention, it is possible to prevent pebbles, gravel, etc. from scattering when weeds, small trees, etc. are cut using a power mower. Since the protective cover of this invention covers the upper surface and the entire circumference, not only the head, face, torso and legs of the person using the mower, but also workers, buildings, pedestrians and cars around it. It can protect against scattering of stones, gravel, etc.

A retrofitted protective cover unit for a lawn mower of the present invention comprises a protective cover, an extension unit for extending a screw extending from an existing gear case provided at the tip of a rod, and a support for supporting the protective cover. , the extension unit has a joint and an extension screw, the protective cover is inserted through the extension screw, and the retrofitted protective cover is attached to the support, so that the protective cover is firmly fixed to the mower. be done. Therefore, the protective cover does not move even when the power lawn mower vibrates, allowing safe and efficient work.

Further, it is particularly preferable to further include a pressing spring for pressing the gear case against the support, since the protective cover is particularly firmly fixed to the lawn mower.

In addition, since the retrofitted protective cover unit for lawn mowers of the present invention can be retrofitted to commercially available power lawn mowers, a protective cover of any size can be selected. Therefore, the power lawn mower equipped with the retrofitted protective cover unit for the lawn mower of the present invention can be used not only on flat ground, but also on slopes, rough terrain, narrow places, grooves, and places with obstacles. It is particularly effective when used on uneven ground, narrow places, grooves, and places with obstacles.
