CROSS REFERENCE TO RELATED APPLICATION [0001]This patent application is related to and claims benefit of priority from U.S. Provisional Patent Application Ser. No. 60/761,836 filed Jan. 25, 2006. FIELD OF THE INVENTION [0002]The present invention relates, in general, to lawn and garden type equipment and, more particularly, this invention relates to a combination turbo garden tiller and a grass trimmer for trimming the grass around the head of a lawn water sprinkler. BACKGROUND OF THE INVENTION [0003]Prior to the conception and development of the present invention, as is generally well known in the prior art, garden tillers and grass trimmers have been sold commercially and are generally in widespread use. [0004]The numerous prior art type garden tillers, which are known to Applicant, are normally rather large and are, therefore, usually not used for small jobs such as tending a small flower garden. Additionally, the prior art type grass trimmers are not specifically designed to trim a circle as is needed around the head of a lawn water sprinkler. Furthermore, to the best of Applicant's knowledge, there is not a single implement presently available on the market which can be readily adapted to do each of these jobs in an efficient manner. SUMMARY OF THE INVENTION [0005]The present invention provides, in a first aspect, a grass trimmer for trimming the grass from around the head of a lawn water sprinkler system. The grass trimmer includes an elongated generally hollow tubular member closed at a first end thereof. Such elongated tubular member having each of a predetermined length and a predetermined diameter. There is a plurality of serrations formed on a second axially opposed end of the elongated generally hollow tubular member for cutting grass disposed around such head portion of such lawn water sprinkler. Additionally, a means engageable with the first closed end of such elongated generally hollow tubular member is provided for manipulating such apparatus for trimming such grass from around such head portion of such lawn water sprinkler system. [0006]In a second aspect, the present invention provides a relatively small garden tiller for at least one of tending, tilling and cultivating the ground around a small garden area to remove unwanted vegetation. Such garden tiller includes a first elongated rod like member having each of a predetermined length and a first predetermined cross-sectional shape in a direction transverse to such predetermined length. A predetermined number of tine members are secured to an outer surface of the elongated rod like member adjacent a first end thereof for penetrating a ground surface in order to at least one of till, weed and cultivate a small garden area. A second elongated rod like member engageable at a first end thereof with a second axially opposed end of said first elongated rod like member is provided. A biasing means is disposed over such second elongated rod like member and caged between a pair of plate like members for absorbing shock during use of the apparatus and a means engageable with a second end of such second elongated rod like member is provided for manipulating such apparatus during such at least one of tilling, weeding and cultivating a small garden area. [0007]The instant invention, in a third and final aspect, provides a combination garden tiller and grass trimmer for at least one of trimming around a lawn water sprinkler head and at least one of tilling, weeding and cultivating a small garden area. This combination garden tiller and grass trimmer for trimming around a lawn water sprinkler head includes an elongated generally hollow tubular member closed at a first end thereof. Such elongated tubular member having each of a predetermined length and a predetermined diameter. A plurality of serrations are formed on a second axially opposed end of the elongated generally hollow tubular member for cutting grass disposed around such head portion of such lawn water sprinkler. An elongated generally hollow housing member at least partially disposed for reciprocal movement within such elongated generally hollow tubular member. The elongated generally hollow housing member being open at a first end thereof and having each of a predetermined length and a predetermined cross-sectional shape in a direction transverse to such predetermined length. A plate like means is disposed at a second end of the axially opposed second end of such elongated generally hollow housing member for closing such second end of the elongated generally hollow housing member and having an outer periphery thereof engageable with an inner surface of such elongated generally hollow tubular member for providing a first portion of a guide means during such reciprocal movement. A second portion of the guide means is disposed around an outer periphery of the elongated generally hollow housing member intermediate each end thereof and having an outer periphery engageable with the inner surface of such elongated generally hollow tubular member for providing a first portion of the guide means during such reciprocal movement. A first elongated rod like member having each of a predetermined length and a first predetermined cross-sectional shape in a direction transverse to said predetermined length is provided to receive a predetermined number of tine members secured to an outer surface thereof adjacent a first end for penetrating a ground surface to at least one of till, weed and cultivate a small garden area. A second elongated rod like member engages at a first end thereof with a second axially opposed end of the first elongated rod like member. A biasing means is disposed over such second elongated rod like member and caged between a pair of plate like members for absorbing shock during use of such apparatus. There is a means engageable with one of such first closed end of the elongated generally hollow tubular member and such second end of such elongated rod like member for manipulating such apparatus for at least one of trimming such grass from around such head portion of such lawn sprinkler and at least one of tilling, weeding and cultivating a small garden area. OBJECTS OF THE INVENTION [0008]It is, therefore, one of the primary objects of the present invention to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which is easy to use. [0009]Another object of the present invention is to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which is less expensive to purchase than when these two items are purchased as separate units. [0010]Still another object of the present invention is to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which is relatively lightweight. [0011]Yet another object of the present invention is to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which requires less storage space than presently available equipment. [0012]A further object of the present invention is to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which can be power operated or manually operated. [0013]An additional object of the present invention is to provide a combination garden tiller and grass trimmer for trimming grass from around the head of a lawn water sprinkler system which will reduce the time required to till a relatively small area and to trim around a water sprinkler head. [0014]In addition to the various objects and advantages of the present invention described with some degree of specificity above it should be obvious that additional objects and advantages of the combination garden tiller and grass trimmer will become more readily apparent to those persons who are skilled in the relevant art from the following more detailed description of the invention, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.
