  • Grass trimming device
    Patent number: 4894914
    Abstract: A grass trimming device is capable of adopting at least two alternative configurations, in one of which a cutting plane is substantially horizontal for use in grass trimming, and in the other of which the cutting plane is substantially vertical for edge trimming. A parting plane is defined by a housing of the cutting head such that rotation about an axis perpendicular to this plane through 180.degree. results in the required switching. The shaft axis is preferably inclined at 10.degree.-15.degree. with respect to the rotational axis.
