Abstract: A lawn trimmer including a cutting disc, a drive shaft; and a flexible drive shaft. The drive shaft is within a straight shaft, connected to the motor and extending to the flexible drive shaft, translating the rotation of the motor to the flexible drive shaft. The flexible drive shaft is within a curved shaft, parallel but not-colinear with the straight shaft, extends to a rotor head connected to the curved shaft, translating drive shaft rotation to a cutting disc comprising a plurality of cutting blades on a cutting plane; an intersection between the cutting plane and the curved shaft axis defines a predetermined oblique angle.

Abstract: The present invention describes a string trimmer support attachment. The device includes a base on which the shaft of a string trimmer can be secured. The present invention further includes a pair of legs that are pivotally attached to the base. The legs can be folded so as to be aligned against the string trimmer shaft when not in use. Alternatively, the legs can be folded outward so that the legs are roughly perpendicular to the string trimmer shaft in order to support the head of a string trimmer in an upright and angled orientation that is convenient for changing the trimmer line. Further, in the unfolded configuration the legs are disposed at an angle relative to one another to provide a stable support for the string trimmer, wherein the string trimmer proximal end acts as a third portion a tripod when the legs are deployed.
