ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to trimming systems and more particularly pertains to a new yard trimming system for attaching to an undercarriage of a vehicle such as a lawn tractor.
2. Description of the Prior Art
The use of trimming systems is known in the prior art. More specifically, trimming systems heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,560,189; U.S. Pat. No. 4,949,536; U.S. Pat. No. 5,226,284; U.S. Patent No. 5,167,108; U.S. Pat. No. Des. 334,200; and U.S. Pat. No. Des. 311,009.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new yard trimming system. The inventive device includes a cutting assembly for cutting plants growing from a ground surface. The cutting assembly preferably comprises a sleeve member and a disk member rotatably mounted to a second end of the sleeve member. A pair of cutting members is mounted on a perimeter edge of the disk for cutting the plants. A mounting assembly is provided for pivotally mounting the cutting assembly to the undercarriage of the vehicle. The mounting assembly preferably comprises a support member with the sleeve member being mounted on a first end of the support member. A pulley assembly is mounted on the support member for selectively providing power from a motor of the vehicle to the cutting assembly.
In these respects, the yard trimming system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of attaching to an undercarriage of a vehicle such as a lawn tractor.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of trimming systems now present in the prior art, the present invention provides a new yard trimming system construction wherein the same can be utilized for attaching to an undercarriage of a vehicle such as a lawn tractor.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new yard trimming system apparatus and method which has many of the advantages of the trimming systems mentioned heretofore and many novel features that result in a new yard trimming system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art trimming systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises a cutting assembly for cutting plants growing from a ground surface. The cutting assembly preferably comprises a sleeve member and a disk member rotatably mounted to a second end of the sleeve member. A pair of cutting members is mounted on a perimeter edge of the disk for cutting the plants. A mounting assembly is provided for pivotally mounting the cutting assembly to the undercarriage of the vehicle. The mounting assembly preferably comprises a support member with the sleeve member being mounted on a first end of the support member. A pulley assembly is mounted on the support member for selectively providing power from a motor of the vehicle to the cutting assembly.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new yard trimming system apparatus and method which has many of the advantages of the trimming systems mentioned heretofore and many novel features that result in a new yard trimming system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art trimming systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new yard trimming system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new yard trimming system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new yard trimming system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such yard trimming system economically available to the buying public.
Still yet another object of the present invention is to provide a new yard trimming system which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new yard trimming system for attaching to an undercarriage of a vehicle such as a lawn tractor.
Yet another object of the present invention is to provide a new yard trimming system which includes a cutting assembly for cutting plants growing from a ground surface. The cutting assembly preferably comprises a sleeve member and a disk member rotatably mounted to a second end of the sleeve member. A pair of cutting members is mounted on a perimeter edge of the disk for cutting the plants. A mounting assembly is provided for pivotally mounting the cutting assembly to the undercarriage of the vehicle. The mounting assembly preferably comprises a support member with the sleeve member being mounted on a first end of the support member. A pulley assembly is mounted on the support member for selectively providing power from a motor of the vehicle to the cutting assembly.
Still yet another object of the present invention is to provide a new yard trimming system that saves a user time and energy by allowing a user to mow their lawn and trim their weeds with a single device. The present invention does not require a user to carrying around a separate device to trim their weeds.
Even still another object of the present invention is
