ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for mowing and/or trimming grass and weeds away from the base of a fence or around the foundation of a building (or exterior wall). More particularly, the invention relates to a string line fence mowers adapted for movement about stationary objects in the path of the mower.
2. Description of the Prior Art
As anyone who has ever cut a lawn will attest, trimmming around trees, fences and other obstacles is one of the most time consuming tasks associated with properly cutting a lawn. With this in mind, a wide variety of trimming apparatuses have been developed for trimming about trees, fences and other obstacles.
Probably the most common device currently employed is a line trimmer. Line trimmers are highly effective, but generally require that an individual carry the trimmer as he or she moves about the obstacle. While this is not a major problem when one attempts to trim small to moderate sized yards, it becomes very time consuming when traditional string trimmers are used to trim a large lot.
A need, therefore, exists for a mowing and/or trimming device which may be moved about a lot to trim around obstacles by a motorized vehicle.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a mowing apparatus. The mowing apparatus includes a frame supported by a plurality of wheels enabling ready movement of the frame over a support surface. The apparatus further includes a cutting assembly secured to the frame, wherein the cutting assembly includes a laterally extending housing rotatably supporting a cutting implement and a motor coupled to the cutting implement for rapidly rotating the cutting implement. The cutting assembly is pivotally secured to the frame for movement about a first axis and a second axis substantially perpendicular to the first axis.
It is also an object of the present invention to provide a mowing apparatus wherein the cutting implement includes a freely rotating support member which supports a string line adapted for mowing. The rotating member includes a first loop, a second loop and a hook about which the string line is wrapped to conveniently secure the string line to the support member.
It is another object of the present invention to provide a mowing apparatus wherein the support member also includes first and second stabilizers for maintaining tension in the string line.
It is a further object of the present invention to provide a mowing apparatus wherein the cutting assembly further includes an end roller positioned at a far end of the laterally extending housing to protect the housing as the mowing apparatus moves past various objects.
It is also an object of the present invention to provide a mowing apparatus wherein the cutting assembly is adapted to be mounted on the frame in a first orientation and a second orientation 180° from the first orientation.
It is another object of the present invention to provide a mowing apparatus wherein the cutting assembly further includes a support roller coupled to the laterally extending housing for maintaining the cutting implement off the ground.
It is a further object of the present invention to provide a mowing apparatus wherein the support roller is adjustably coupled to the cutting assembly.
It is also an object of the present invention to provide a mowing apparatus wherein a mounting bracket adjustably couples the support roller to the cutting assembly, and the mounting bracket includes a plurality of aligned openings in which the roller is selectively positioned.
It is another object of the present invention to provide a mowing apparatus including means for limiting pivotal movement about the first axis.
It is a further object of the present invention to provide a mowing apparatus wherein the means for limiting includes a line coupled between the cutting assembly and the frame for limiting movement about the first axis.
It is also an object of the present invention to provide a mowing apparatus wherein the means for limiting includes a projecting arm limiting movement about the first axis.
It is another object of the present invention to provide a mowing apparatus including a frame supported by a plurality of wheels enabling ready movement of the frame over a support surface and a cutting assembly including a support roller coupled to the laterally extending housing for maintaining the cutting implement off the ground.
It is a further object of the present invention to provide a mowing apparatus including a frame supporting a cutting implement coupled to a motor which drives the cutting implement. The cutting implement includes a freely rotating support member which supports a string line adapted for mowing. The support member includes a first loop, a second loop and a hook about which the string line is wrapped to conveniently secure the string line to the support member.
It is also an object of the present invention to provide a mowing apparatus wherein the support member also includes first and second stabilizers for maintaining tension in the string line.
It is another object of the present invention to provide a mowing apparatus wherein the first stabilizers is positioned between the first loop and the hook and the second stabilizer is positioned between the second loop and the hook.
It is a further object of the present invention to provide a mowing apparatus wherein the stabilizers are projecting posts about which the string line is wrapped.
It is also an object of the present invention to provide a mowing apparatus wherein the first loop and the second loop are positioned on opposite sides of the support member.
Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.
