Abstract
Abstract Handle means provides a frame on which a cutter head may be supported spaced from a hand grip whereby, when the user is standing, the cutter head may be positioned adjacent the ground. The cutter head is a rotatable head including attachment means for attaching at least one flexible flail which extends outward when rotated. The drive means may be electrical or other motor means preferably mounted proximate to the cutter head, but including versions mounted remotely but having an extended flexible shaft enabling drive of the cutter head attached to the rotatable shaft. A circular shield is rotatably supported on the shaft, so that it is independent of the shaft's rotation, preferably outboard of the cutter head. The cutter head provides attachment means which may simply be a hole associated with and opposed to a post or hook, whereby a loop or bight of filamentary material may be placed over the hook or post and the filamentary material extended through the hole which is radially outboard of the motor shaft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
An apparatus for cutting vegetation and the like comprising: a rotatable cutting head including attachment means for attaching at least one flexible flail which extends outward in a plane essentially perpendicular to the axis during rotation; handle means providing hand grip means and supporting the rotatable cutting head spaced from the handle means to enable a user, while standing, to support the cutting head near the ground in selected attitudes including with its axis of rotation generally perpendicular to the ground, a motor supported on the handle means remote from the hand grip so that its rotatable shaft and the cutting head which it supports and drives may be positioned selectively either generally parallel or perpendicular to the ground while held by the handle when the user is standing, and; a shield formed so as to alternatively function as a wheel that is rotatably supported on the drive shaft outboard from the cutting head, spaced from and parallel to the plane of rotation of the flail, so that the shield is independent of the rotation of the shaft and is functionable in supporting and positioning the cutting head when its axis of rotation is horizontal to the ground.
Claim 2
Independent Claim
198 words
An apparatus for cutting vegetation and the like comprising: a rotatable cutting head including attachment means for attaching at least one flexible flail which extends outward in a plane essentially perpendicular to the axis during rotation; handle means providing hand grip means and supporting the rotatable cutting head spaced from the handle means to enable a user, while standing, to support the cutting head near the ground in selected attitudes including with its axis of rotation generally perpendicular to the ground, a motor supported on the handle means remote from the hand grip so that its rotatable shaft and the cutting head which it supports and drives may be positioned selectively either generally parallel or perpendicular to the ground while held by the handle when the user is standing, and; a shield formed so as to alternatively function as a wheel that is rotatably supported on the drive shaft outboard from the cutting head, spaced from and parallel to the plane of rotation of the flail, so that the shield is independent of the rotation of the shaft and is functionable in supporting and positioning the cutting head when its axis of rotation is horizontal to the ground.
Claim 3
Independent Claim
173 words
An apparatus for cutting vegetation and the like comprising: a rotatable cutting head including attachment means for attaching at least one flexible flail which extends outward in a plane essentially perpendicular to the axis during rotation; handle means providing hand grip means and supporting the rotatable cutting head spaced from the handle means to enable a user, while standing, to support the cutting head near the ground in selected attitudes including with its axis of rotation generally perpendicular to the ground; adjustment means whereby the attitude of the cutting head may be adjusted by releasable positioning means permitting adjustment of the cutting head relative to the handle means; a drive means supported by the handle means and providing a rotatable drive shaft connected to and driving the rotatable driving head, and; a shield generally circular in shape and rotatably supported on the drive shaft outboard from the cutting head, spaced from and parallel to the plane of rotation of the flail, so that the shield is independent of the rotation of the shaft.
Claim 4
Independent Claim
173 words
An apparatus for cutting vegetation and the like comprising: a rotatable cutting head including attachment means for attaching at least one flexible flail which extends outward in a plane essentially perpendicular to the axis during rotation; handle means providing hand grip means and supporting the rotatable cutting head spaced from the handle means to enable a user, while standing, to support the cutting head near the ground in selected attitudes including with its axis of rotation generally perpendicular to the ground; adjustment means whereby the attitude of the cutting head may be adjusted by releasable positioning means permitting adjustment of the cutting head relative to the handle means; a drive means supported by the handle means and providing a rotatable drive shaft connected to and driving the rotatable driving head, and; a shield generally circular in shape and rotatably supported on the drive shaft outboard from the cutting head, spaced from and parallel to the plane of rotation of the flail, so that the shield is independent of the rotation of the shaft.
Claim 5
Dependent Claim
47 words
The apparatus of claim 2 in which the releasable positioning means permits holding the cutting head generally parallel to the ground with the axis of rotation vertical or with the axis of rotation generally horizontal so that the shield may be used as a guide for edging.
Claim 6
Dependent Claim
14 words
The apparatus of claim 2 in which the driving means is an electric motor.
Claim 7
Independent Claim
122 words
An apparatus for cutting vegetation and the like comprising: a drive means having a stator portion and a rotatable drive shaft; handle means supporting the stator portion of the drive means arranged so that the drive shaft is located at one end of the handle means and providing a hand grip means at a position to enable a user while standing to support the drive shaft near the ground; attachment means on the shaft including means providing an associated hole and a hook, and; a continuous length of flexible monofilament material looped in a manner to double back upon itself forming a looped end and where said looped end is extended through said hole of said means and secured to said hook.
Claim 8
Independent Claim
122 words
An apparatus for cutting vegetation and the like comprising: a drive means having a stator portion and a rotatable drive shaft; handle means supporting the stator portion of the drive means arranged so that the drive shaft is located at one end of the handle means and providing a hand grip means at a position to enable a user while standing to support the drive shaft near the ground; attachment means on the shaft including means providing an associated hole and a hook, and; a continuous length of flexible monofilament material looped in a manner to double back upon itself forming a looped end and where said looped end is extended through said hole of said means and secured to said hook.
Claim 9
Dependent Claim
35 words
The apparatus of claim 5 in which the attachment means is a plate having at least one flange extending perpendicular to said plate and having the hole therein for receiving said continuous length of monofilament.
Claim 10
Dependent Claim
33 words
The apparatus of claim 5 in which the hook is a tang formed in a configuration so as to provide a wedging action upon the monofilament as it is pulled in one direction.
