The disclosure and prior art relates to harrows and more particularly pertains to a new harrow for smoothing horse pens.
An embodiment of the disclosure meets the needs presented above by generally comprising a vehicle carabiner that is configured to selectively engage with an ATV, a UTV, or a small tractor. A pair of chains is coupled to the vehicle carabiner. Each of the pair of chains has a vehicle end coupled to the vehicle carabiner and a harrow end. A lead harrow bar is coupled to the pair of chains. The lead harrow bar has a first left end, a first right end, a first leading face, a first trailing face, a first bottom face, and a first top face. A pair of first front eyelets is coupled to the first leading face proximal the first top face and a pair of first rear eyelets coupled to the first trailing face proximal the first top face. The pair of first front eyelets is coupled to the harrow end of the pair of chains. There is a second harrow bar having a second left end, a second right end, a second leading face, a second trailing face, a second bottom face, and a second top face. A pair of second front eyelets is coupled to the second leading face proximal the second top face and a pair of second rear eyelets is coupled to the second trailing face proximal the second top face. A pair of linkage systems is coupled between the pair of rear eyelets of the lead harrow bar and the pair of front eyelets of the second harrow bar of the plurality of harrow bars. A plurality of tines is coupled to the first bottom face of the lead harrow bar and the second bottom face of the second harrow bar.
There has thus been outlined, rather broadly, the more important features of the disclosure 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 disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A pair of linkage systems 58 may be coupled to the lead harrow bar 22 and the second harrow bar 40. Each of the pair of linkage systems 58 may comprise a pair of linkage carabiners 60, a pair of D-rings 62, and a linkage bar 64. The pair of D-rings 62 is coupled to a front end 66 and a back end 68 of the linkage bar, the pair of linkage carabiners 60 is coupled to the pair of D-rings 62, and the pair of D-rings 62 is selectively engageable with the pair of first rear eyelets 38 of the lead harrow bar and the pair of second front eyelets 54 of the second harrow bar.
A plurality of tines 70 is coupled to each of the lead harrow bar 22 and the second harrow bar 40. The plurality of tines 70 may comprise a plurality of tine pairs 72, each of the tine pairs being a V-shape and having a vertex 74. Each of the tine pairs 72 may have a long tine 76 and a short tine 78. The vertex 74 is coupled to each of the first bottom face 32 of the lead harrow bar and the second bottom face 50 of the second harrow bar and may be 30° from the pair of first front eyelets 36 and the pair of second front eyelets 54 and 150° from the pair of first rear eyelets 38 and the pair of second rear eyelets 56, respectively. The plurality of tine pairs 72 may be eleven pairs with six tine pairs coupled to the lead harrow bar 22 and five tine pairs coupled to the second harrow bar 40. The plurality of tine pairs 72 is coupled to the lead harrow bar 22 a first end distance 80 from the first left end 24 and the first right end 26 and a gap distance 82 between each adjacent tine pair, and to the second harrow bar 40 a second end distance 84 from the second left end 42 and the second right end 44 and the gap distance between each adjacent tine pair. The second end distance 84 is greater than the first end distance 80 to stagger the tine pairs between the lead harrow bar 22 and the second harrow bar 40. The first end distance 80 may be 7.62 cm, the second end distance 84 may be 20.3 cm, and the gap distance 82 may be 20.3 cm.
In use, the vehicle carabiner 12 is coupled to the ATV 14, UTV, or small tractor to drag the lead harrow bar 22 and, optionally, the second harrow bar 40 with the plurality of tines 70 loosening the dirt of a horse pen 86. The second harrow bar 50 may also be rotated such that the second top face 52 contacts the ground to smooth the dirt. An additional lead harrow bar 22 may be coupled to the pair of second rear eyelets 56 of the second harrow bar with an additional pair of linkage systems 58 for the modular harrow apparatus 10 to be used with three harrow bars.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
