Abstract
A grooming device for use on a walk behind mower which has an operator's handle. The lawn grooming device includes an adjustable tow bar mounted on an operators handle of the walk behind lawn mower; a hitch member mounted on the adjustable tow bar; and a weighted earth engaging roller assembly releasably coupled to the hitch member, and oriented in trailing relation relative to the walk behind lawn mower, and wherein the weighted roller assembly is pivotally moveable in both a horizontal and vertical plane relative to the tow bar.
Claims33
A lawn grooming device for use on a walk behind lawn mower having a rearwardly extending operator's control handle, comprising:
- an adjustable tow bar mounted on an operator's handle of a walk behind lawn mower, the tow bar being adjustable as to width and length;
- a hitch member mounted on the adjustable tow bar;
- and
- an earth engaging roller assembly releasably coupled to the hitch member, and oriented in trailing relation relative to the walk behind lawn mower, and wherein the roller assembly is pivotally moveable in both a horizontal and vertical plane relative to the tow bar.
(canceled)
A lawn grooming device for use on a walk behind lawn mower, comprising:
- a releasably adjustable tow bar depending downwardly relative to an operator's handle which is mounted on a rear end of the walk behind lawn mower, and wherein the releasably adjustable tow bar is adjustable as to length, width and angular orientation relative to the operator's handle;
- the releasably adjustable tow bar comprising:
- first and second generally vertically oriented support members mounted on the operator's handle and depending downwardly therefrom, and wherein the first and second vertically oriented support members are individually adjustable as to length;
- and
- a substantially horizontally oriented connector member mounted on, and extending between the respective first and second generally vertically oriented support members, and wherein the horizontally oriented connector member is adjustable as to length, and wherein the hitch member is mounted about midway along the length of the substantially horizontally oriented connector member
- a hitch member mounted on the adjustable tow bar;
- a frame having a leading and a trailing edge, and wherein the leading edge is releasably engaged by the hitch member, and wherein the frame further defines a transversely disposed cavity located between the leading and trailing edges, and wherein the frame is moveable in both horizontal and vertical planes relative to the walk behind lawn mower;
- an earth engaging roller rotatably mounted in the cavity which is defined by the frame, and wherein the roller further has an internal cavity;
- and
- a flowable substance received within the internal cavity of the earth engaging roller and which increases the weight of the earth engaging roller to a degree which allows it to effectively bend blades of grass to produce an aesthetically appealing appearance on a grass surface over which the earth engaging roller travels.

A lawn grooming device for use on a walk behind lawn mower having a rearwardly extending operator's handle, comprising:
- a first portion of an attachment assembly having a main body defined by an outside facing surface, and an inside facing surface, and wherein the inside facing surface defines a channel which is dimensioned to conformably receive and mate with a portion of the operator's handle;
- a second portion of an attachment assembly which has a main body defined by an outside facing surface, and an inside facing surface, and wherein the inside facing surface defines a channel which is dimensioned to conformably receive and mate with a portion of the operator's handle and matingly fit together with the first portion, and wherein the first and second portions are fastened together so as to securely capture the operator's handle therebetween, and wherein the outside facing surface further defines a plurality of spaced orientation teeth, and a region for receiving a distal end of a depending substantially vertically oriented support member;
- a third portion of an attachment assembly having a main body defined by an outside facing surface, and an inside facing surface, and wherein the inside facing surface defines a channel which is dimensioned to conformably receive and mate with a portion of the distal end of the depending substantially vertically oriented support member and secure the distal end therebetween the second and third portions, and wherein the third portion includes a plurality of spaced orientation teeth which matingly cooperate with the plurality of spaced orientation teeth made integral with the second portion so as to permit the third portion to orient the depending substantially vertically oriented support member in a plurality of predetermined angular orientations;
- a substantially horizontally oriented connector member mounted on the substantially vertically oriented support member;
- a hitch member mounted on the substantially horizontally oriented connector member;
- a frame having a leading and a trailing edge, and wherein the leading edge is releasably engaged by the hitch member, and wherein the frame further defines a transversely disposed cavity located between the leading and trailing edges, and wherein the frame is moveable in both horizontal and vertical planes relative to the walk behind lawn mower;
- an earth engaging roller rotatably mounted in the cavity which is defined by the frame, and wherein the roller further has an internal cavity;
- and
- a flowable substance received within the internal cavity of the earth engaging roller and which increases the weight of the earth engaging roller to a degree which allows it to effectively bend blades of grass to produce an aesthetically appealing appearance on a grass surface over which the earth engaging roller travels.
A lawn grooming device comprising:
- a tow bar;
- a weighted roller;
- a frame connecting the weighted roller to the tow bar;
- and
- an angularly adjustable attachment device configured to attach the tow bar to an operator's handle of a walk-behind mower, the angularly adjustable tow bar having an inner portion, a center portion having spaced orientation teeth, and an outer portion having spaced orientation teeth, the spaced orientation teeth of the center portion being positioned to matingly cooperate with the spaced orientation teeth of the outer portion such that the angularly adjustable attachment device is adjustable so as to change the angle of the tow bar relative to the operator's handle;
- and
- wherein the tow bar extends downwardly relative to the operator's handle and is disposed in spaced relation relative to a surface of the earth, the walk-behind mower having a grass catching bag which is releasably mounted on the walk-behind mower and which extends rearwardly thereof, positioned between the operator's handle and the surface of the earth such that the tow bar does not interfere with the operation of the grass catching bag.
A lawn grooming device as claimed in claim 30, and wherein the vertical and horizontal dimensions of the tow bar are adjustable.
