     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to  FIGS. 1 through 5  thereof, a new cutting device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
     As best illustrated in  FIGS. 1 through 5 , the remotely powered cutting assembly  10  generally comprises a power unit  12  that may be worn. The power unit  12  comprises a box  14  that has an outer wall  16  and a top side  18 . The top side  18  is open to access an interior of the box  14 . A lid  20  is provided and the lid  20  is removably positioned on the top side  18 . The outer wall  16  has a first lateral side  22 . 
     A pair of straps  24  is provided and each of the straps  24  is coupled to the outer wall  16 . Thus, each of the straps  24  may be extended over an associated one of a pair of shoulders thereby facilitating the box  14  to be worn. Each of the straps  24  is matable to themselves such that each of the straps  24  forms a closed loop. Moreover, each of the straps  24  may have an adjustable length. 
     In an alternative embodiment  26  as shown in  FIG. 2 , a sleeve  28  may be coupled to the outer wall  16  of the box  14 . A first belt  30  may be provided and the first belt  30  may have a first end  32  and a second end  34 . The first belt  30  may be extended through the sleeve  28  and the first belt  30  may be worn around a waist. The first end  30  is matable to the second end  34 . Thus, the box  14  may be worn. 
     Continuing in the alternative embodiment  26 , the first belt  30  may include a pair of auxiliary straps  36 . The auxiliary straps  36  are matable to each other. Thus, the auxiliary straps  36  may facilitate additional security when the box  14  is worn. Each of the auxiliary straps  36  may comprise complementary hook and loop fasteners or the like. 
     The alternative embodiment  26  may include a second belt  38  that may be attached to the outer wall  38  of the box  14 . The second belt  38  may have a primary end  40  and a secondary end  42 . The second belt  38  may be worn around a leg. The primary end  40  is matable to the second end  42 . Thus, the box  14  may be worn. 
     A motor  44  is provided and the motor  44  is positioned within the box  14 . The motor  44  may comprise an internal combustion motor or the like. A drive shaft  46  is mechanically coupled to the motor  44 . Thus, the motor  44  rotates the drive shaft  46  when the motor  44  is turned on. 
     The drive shaft  46  extends outwardly from the outer wall  38  of the box  14 . Moreover, the drive shaft  46  has a distal end  48  with respect to the box  14 . The drive shaft  46  is comprised of a flexible material. The drive shaft  46  may comprise a flexible central member rotatably extending through an outer sheath or the like. The drive shaft  46  may extend outwardly from the first lateral side  22  of the box  14 . Thus, the drive shaft  46  may extend laterally away from a user when the box  14  is worn. 
     A cutting unit  50  is provided. The cutting unit  50  may be manipulated thereby facilitating the cutting unit  50  to cut objects  52 . The objects  52  may be tree trunks, tree branches and other forms of vegetative brush. The cutting unit  50  is in mechanical communication with the power unit  12 . Thus, the cutting unit  50  inhibits hands from being exposed to vibration associated with the power unit  12  thereby inhibiting development of carpal tunnel syndrome. Moreover, the remote positioning of the power unit  12  with respect to the cutting unit  50  inhibits the hands from supporting the weight of the power unit  12 . Thus, the cutting unit  50  reduces muscular fatigue associated with carrying the power unit  12  with hands. 
     The cutting unit  50  comprises a chainsaw  54  that may be manipulated. The chain saw  54  has a drive  56  and a blade  58  is that mechanically coupled to the drive  56 . Thus, the drive  56  rotates the blade  58  when the drive  56  rotates. The drive  56  may comprise a mechanical drive or the like and the blade  58  may comprise a chain saw blade or the like. 
     The distal end  48  of the drive shaft  46  is mechanically coupled to the drive  56 . The drive shaft  46  rotates the drive  56  when the motor  44  is turned on. Thus, the chainsaw  54  may cut the objects  52 . The chainsaw  54  may include a handle, a chain guard, a trigger and other conventional, mechanical elements of a motorized chainsaw. 
     A switch  60  is coupled to the chainsaw  54  and the switch  60  may be manipulated. The switch  60  is electrically coupled to the drive  56 . The switch  60  selectively disengages and engages the drive  56  with respect to the drive shaft  46 . Thus, the switch  60  selectively inhibits and facilitates the drive shaft  46  to rotate the blade  58 . The switch  60  may be in mechanical communication with the drive  56  through any conventional means such as an electronic clutch or the like. 
     A grip  62  is provided. The grip  62  has a central member  64  extending between a pair of lateral members  66 . The lateral members  66  are spaced apart from each other such that the grip  62  has a U-shape. Each of the lateral members  66  has a distal end  68  with respect to the central member  64 . The distal end  68  corresponding to each of the lateral members  66  is coupled to the chainsaw  54 . The central member  64  is spaced from the chainsaw  54  and the central member  64  may be gripped. The grip  62  is comprised of an electrically conductive material. The grip  62  is between the blade  58  and the drive  56 . 
     A touch sensor  70  is provided and the touch sensor  70  is coupled to the chainsaw  54 . The touch sensor  70  is electrically coupled to the grip  62 . Thus, the touch sensor  70  senses when the grip  62  is touched. The touch sensor  70  is electrically coupled to the drive  56 . The touch sensor  70  turns the drive  56  on when the touch sensor  70  senses the grip  62  is touched. Moreover, the touch sensor  70  turns the drive  56  off when the touch sensor  70  does not sense the grip  62  is touched. Thus, the blade  58  does not move when the grip  62  is not gripped thereby enhancing safety of the chainsaw  54 . 
     In use, the box  14  is worn in the previously described manner. The motor  44  is started and the chainsaw  54  is held. The remote location of the motor  44  with respect to the chainsaw  54  inhibits the user&#39;s hands from being exposed to vibration from the motor  44 . Thus, the user&#39;s hands are inhibited from developing symptoms of carpal tunnel syndrome related to the vibration from the motor  44 . The switch  60  is manipulated and the grip  62  is gripped to selectively actuate and de-actuate the blade  58 . The chainsaw  54  is manipulated to cut the objects  52 . 
     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.
