A work machine and work implement for a work machine are disclosed with a hydraulic system enabling greater rotation of the work implement relative to the work machine without providing excess hydraulic line to accommodate such rotation. More specifically, the work machine may include a first hydraulic fluid line extending from a pump of the work machine along a work arm pivotally attached to the work machine, and a second hydraulic fluid line extending from the work implement toward the work arm. The hydraulic swivel coupling may be provided at the a pivot point between the work arm and the work implement where the first and second hydraulic fluid lines can be connected to the hydraulic swivel coupling. 1. A work machine , comprising:a chassis;a work arm pivotally attached to the chassis at a first pivot point;a work implement pivotally attached to the work arm at a second pivot point;a hydraulic fluid pump supported by the chassis;a first hydraulic fluid line extended from the pump to the second pivot point;a second hydraulic fluid line extended from the work implement to the second pivot point; anda hydraulic swivel coupling at the second pivot point, the first and second hydraulic fluid lines being connected to the hydraulic swivel coupling.2. The work machine of claim 1 , wherein the work machine is selected from the group of work machines consisting of loaders claim 1 , excavators claim 1 , compactors claim 1 , track-type tractors claim 1 , skid steers claim 1 , telehandlers claim 1 , and motor graders.3. The work machine of claim 2 , wherein the work implement is selected from the group of implements consisting of augers claim 2 , blades claim 2 , brooms claim 2 , buckets claim 2 , cold planers claim 2 , couplers claim 2 , cutters claim 2 , forks claim 2 , handlers claim 2 , grapplers claim 2 , plows claim 2 , rakes claim 2 , thumbs claim 2 , vibratory compactors claim 2 , shears claim 2 , rippers claim 2 , scoops claim 2 , backhoes claim 2 , brushcutters ...
