Abstract

A combination blade and cord weed cutter-trimmer head apparatus that incorporates a mounting head, having a base plate, that mounts an electric or gas motor, its motor shaft extending downwardly, and through an adapter connects with generally through the cutter blade, with the shaft extending further downwardly for connecting with the string trimmer head of the device. Thus, the device can cut thicker weeds and brush through the application of its cutter blade, and can cut the shortened weeds down to an acceptable level through the usage of the string trimmer. Slip clutches may be incorporated within the device, to allow the motor shaft to continue rotating, in the event that the cutter blade encounters an unmovable obstacle, that prevents its rotation. In a further embodiment, the lines of the string trimmer may extend radially outwardly from the cutter blades, through integral channels provided therein, to provide simultaneous cutting at the same level by both the cutter blade, and the string trimmer, during usage. In a further embodiment, the string trimmer head may locate above the cutter blade both securing onto the motor shaft and held by the adapter to provide for cutting of both weeds and brush during usage.

Claims (11)

1. A trimmer comprising:

a handle having a first end and a grip end to be gripped by an operator;

a mounting head connected to the first end of the handle, the mounting head further comprising a base plate, a motor on the base plate, the motor having a rotatable shaft extending through the base plate;

a cutting blade provided on the shaft;

a first slip clutch provided on the shaft and engaging a surface of the base plate and a first surface of the cutting blade;

a second slip clutch provided on the shaft and engaging a second surface of the blade opposite the first surface of the blade;

a trimmer head secured to an end of the shaft, the trimmer head having a line cutter, the second slip clutch engaging a surface of the trimmer head;

wherein rotation of the shaft via the motor results in rotation of the cutting blade and the trimmer head; and

when the shaft is rotating via the motor and the cutting blade is in a position where the cutting blade is unable to rotate, the shaft and the trimmer head will continue to rotate via the slip clutches.
