Abstract
A lawn grooming device is described and which includes a tow bar coupled to an overland vehicle; a drawbar support frame mounted on the tow bar; a first weighted earth engaging roller assembly affixed to the drawbar support frame; a drawbar mounted on the drawbar support frame; a flexible coupling mounted on the drawbar and which is resiliently moveable in either the horizontal or vertical directions; and a second weighted earth engaging roller assembly mounted on the coupling and disposed in trailing relation relative to the first weighted earth engaging roller assembly.
Claims20
A lawn grooming device, comprising:
- a tow bar releasably coupled to a self-propelled overland vehicle;
- a drawbar support frame mounted on the tow bar;
- a first weighted earth engaging roller assembly affixed to the drawbar support frame;
- a drawbar mounted on the drawbar support frame, and which further is adjustable as to length, and the first weighted earth engaging roller assembly is mounted between the drawbar support frame and the drawbar;
- a coupling mounted on the drawbar and which is resiliently moveable in either the horizontal or vertical directions;
- and
- a second weighted earth engaging roller assembly mounted on the coupling and disposed in trailing relation relative to the first weighted earth engaging roller assembly.
A lawn grooming device, comprising:
- a tow bar having a first end which releasably engages a rear hitch mounted on a rear end of a lawn tractor, and an opposite second end, and wherein a handle is mounted on the first end of the tow bar, and further has laterally disposed portions which operate to engage the rear end of the lawn tractor to limit the angular orientation that the tow bar may be moved relative to the rear end of the lawn tractor;
- a drawbar support frame mounted on the second end of the tow bar and which has two spaced arms, each having a distal end, and wherein the distal ends are spaced a given distance apart, and wherein the respective arms are oriented in predetermined substantially parallel spaced relation laterally outwardly relative to the tow bar;
- a frame supporting member mounted on the distal end of each of the arms of the drawbar support frame;
- a first weighted earth engaging roller assembly mounted on the second end of the tow bar, and wherein the first weighted earth engaging roller assembly includes a frame having a leading and a trailing edge, and wherein the leading edge is mounted on the second end of the tow bar, and the frame further defines opposite ends, and a transversely disposed cavity located between the leading and trailing edges, and wherein an earth engaging roller is rotatably mounted in the transversely disposed cavity, and the frame support members are individually releasably affixed to the opposite ends of the frame;
- a drawbar which is releasably mounted on the distal ends of the arms of the drawbar support frame, and wherein the drawbar has opposite ends and an internal cavity, and wherein a first and second adjustment member is received, at least in part, within the internal cavity of the drawbar, and individually extends longitudinally outwardly relative to the opposite ends of the drawbar, and wherein the first and second adjustment members each have a distal end which can be located at variable distances longitudinally outwardly relative to the opposite ends of the drawbar;
- a resilient coupler mounted on the distal end of the respective first and second adjustment members, and which can be rendered simultaneously resiliently moveable in both vertical and horizontal directions upon the application of force;
- and
- a second pair of earth engaging roller assemblies which are individually mounted on the respective resilient couplers, and which are further disposed laterally outwardly, and in trailing relationship relative to the first earth engaging roller assembly, and wherein the respective second pair of earth engaging roller assemblies are independently moveable in both the horizontal and vertical directions.
A lawn grooming device as claimed in 18, and wherein the overlapping rolling relationship of the first and second earth engaging rollers has a width dimension of about 38 to about 52 inches.
A lawn grooming device as claimed in 18, and wherein the handle is longitudinally moveable along the tow bar so as to adjust the range of the angular orientation of tow bar relative to the rear end of the lawn tractor.
