Abstract: A string trimmer having a head with aerodynamic cutting line with a long beam axis and a pitch angle may be used for both vegetation cutting and as a blower. A gear box may be provided for changing the gear ratio from the engine or motor to the head depending upon the pitch angle. Optimum cutting operation is provided with a pitch angle of about 0-10°, and when used as a blower the optimum pitch angle is between about 15-45° upward. The string trimmer may be mounted on a cart having a bottom frame with at least three wheels, first and second adjustable length arms each rotatably mounted by the substantially vertical axis and having a free end, and a clamp at the first arm free end for clamping the shaft of the string trimmer, and a clamp or flexible band or cord at the end of the second arm, typically also for engaging the string trimmer shaft to provide substantially 360° freedom of movement thereof.

Abstract: A vegetation cutter, a cutting string for use with a vegetation cutter, and a method of cutting vegetation, are provided which utilize a novel cutting string arrangement in which a twist and living hinge are provided in a cutting string having a drag co-efficient of less than 1.0, typically with a first long axis and a second short axis, the second axis less than 85% of the first axis. The twist is provided between the free end of the string and where the string is mounted to the head, or where two twists are provided in the string, the string is mounted to the head at a central portion between the twists. The string may be mounted to the head by grooves or slots and/or clamping mechanisms, or a wide variety of other components. The cutting string may have a wide variety of cross-sectional configurations (both symmetrical, such as elliptical, or non-symmetrical, such as substantially tear drop). The twist is typically between about 30-150°, most desirably about 90°.

Abstract: A vegetation cutting implement includes a rotatable support head which mounts a hub having a plurality of cutter elements comprising self-supporting struts. Each strut is more than 50% non-metallic material (typically more than 90% plastic or rubber), and the hub is readily replaceable in the vegetation cutting implement merely by detaching a fastener. Typically the cutter elements are integral with the hub, although a number of radially extending openings may be provided through which individually replaceable cutter elements pass. The self-supporting struts each preferably comprise a beam-like structure with a first axis which is the strongest axis and has a highest moment of inertia and a second, weaker axis, and the head is rotated so that the first axis of the beam-like structure of each strut is positively maintained and moves in a predetermined cutting plane which is generally transverse to a portion of vegetation to be cut.

Abstract: An elongated flexible cutting string, or substantially self-supporting strut cutting element, is connectable to a rotating device for use in a method of cutting vegetation. The cutting string has numerous advantages over conventional cutting strings, having a drag coefficient which is at least about 5% (e.g. 10-300%) less than the drag coefficient of a string having a substantially round and smooth cross-section. The drag coefficient of aerodynamic line 10 is 1.0 or less, e.g. about 0.35 or less. The cross-sectional configuration preferably simulates a tear drop (with or without an extension nose), and can have a textured (e.g. with golf ball simulating dimples, saw toothed or a wavy configuration) exterior surface. The pitch of the line is positively maintained while it is rotated in a cutting plane, e.g. controlled with an eyelet and/or a compound taper. Other cross-sectional configurations are an ellipse of at least 1.

Abstract: The Cue Putter is unique golf club, far superior in design to existing putters. It is designed to maximize a golfer's putting accuracy and consistency. The Cue Putter consists of a wooden club shaft, a guide block, rubber "O"-rings, and a transparent Plexiglas clubhead. The Cue Putter is designed to be used while kneeling on the green, with the putter's shaft aligned and used parallel to the putting surface. The Cue-Putter is gripped with one hand, and the stroke is executed primarily with the fingers and wrist instead of the arms and shoulders used with traditional putters. This improves the golfer's putting "touch" tremendously, because the innate precision of the hand and fingers cannot be matched by the larger muscle groups of the arms and shoulders. The Cue Putter also provides an ideal, "real time" view of the slope and undulation of the green, instead of a vague, "mental snapshot" taken while the golfer crouches down yards behind the ball prior to assuming his stance.

Abstract: An aerodynamic cutting string for use with such devices as flexible line trimmers and the like. The string incorporates a number of embodiments which eliminates or greatly reduces the drag, fluttering and force imbalances which are created as a result of the pressure differential and wake which are formed behind the flexible line as it moves. This accomplishment is achieved by employing an aerodynamic profile for the line which lowers the coefficient of drag and reduces the forces created by the air foil.
