DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(6) Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed a system for a hydraulic tree branch shear 10 that basically includes a shear assembly 20 and a skid-steer loader 40.

(7) Shear assembly 20 includes a base 22 and an elongated body 23. Base 22 may be rectangular in shape and comprise of a suitable metal material. In a preferred embodiment base 22 is of a shape that cooperates with that of skid-steer loader 40. Elongated body 23 comprises an elongated cubic shape made of a suitable metal material. The elongated shape of elongated body 23 allows a user to reach hard to reach areas containing tree branches. Elongated body 23 is welded thereon a center portion of base 22. Elongated body 23 further includes an elongated body base 23 disposed near the end of elongated body 23. Elongated body base 23 comprises may comprise a square shape and is made of a suitable metal material. Shear assembly 20 further includes support members 24 mounted thereon base 22 and elongated body base 23A. In the present embodiment, support members 24 are welded thereon base 22 and elongated body base 23A. Support members 24 are made of a suitable metal material and provide shear assembly 20 the necessary support needed to lift elongated body 23. Shear assembly 20 further comprises a head 25 disposed on elongated body 23. Head 25 is disposed on the end opposite to the end attached to base 22. Head 25 is further made of a suitable metallic material and may comprises of a rectangular shape including an open portion 26. Open portion 26 is open space disposed on the top end of head 25. Head 25 further includes a jaw 27 disposed on the bottom end of head 25. Jaw 27 is made of a suitable metallic material and further comprises teeth 27A thereon. Jaw 27 is of a suitable size to receive a tree branch therein. Furthermore, teeth 27A should be sharp in nature to aid a user in cutting through tree branches. It should be understood that any number of teeth 27A may be included on jaw 27 and is not limited to the number of teeth 27A depicted in the drawings. Jaw 27 is mounted thereon head 25 using a pivoting member 28 disposed on head 25. Pivoting member 28 allows jaw 27 to open and close thereby providing a snapping means for cutting tree branches. Shear assembly 20 further includes a hydraulic attachment 29 attached to jaw 27. Hydraulic attachment 29 as known in the art provides the necessary closing force to jaw 27 for cutting down tree branches. Hydraulic attachment 29 further comprises hydraulic lines 29A to communicably mount hydraulic attachment 29 to skid-steer loader 40.

(8) Shear assembly 20 is mounted unto skid-steer loader 40. Skid-steer loader 40 includes bucket couplers 42 thereon. Base 22 of shear assembly 20 is mounted onto skid-steer loader 40 using bucket couplers 42. In the present embodiment, bucket couplers 42 are existing bucket couplers located on skid-steer loader 40. Skid-steer loader 44 further includes controls 44 thereon. In the present embodiment, controls 44 are existing controls located on skid-steer loader 40. In system for a hydraulic tree branch shear 10 shear assembly 20 is mounted onto skid-steer loader 40 thereon. A user mounts base 22 to skid-steer loader 40 using bucket couplers 42. Once safely secured, a user may then attach hydraulic lines 29A to existing controls 44 of a skid-steer loader 40. Afterwards, a user may then utilize skid-steer loader 40 to operate shear assembly 20. A user can operate skid-steer loader 40 to position head 25 into a tree branch a user desires to cut off. Once head 25 is properly positioned on a tree branch, a user may then use controls 44 to actuate jaw 27. Once actuated jaw 27 clamps down on head 25 using the hydraulic power supplied by skid-steer loader 40. The resulting force coupled with the sharp edges of teeth 27A allows a user to efficiently and effortlessly cut down a tree branch. A user may continue to operate skid-steer loader 40 having shear assembly 20 thereon to cut down any number of desired tree branches.

(9) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
