Hydraulic hoses associated with an implement attachment assembly may be removably coupled to a lift arm when in a non-operating configuration, and removably coupled to the attachment assembly when in an operating configuration. ## Claims ### Claim 1 A lift arm comprising: an implement attachment interface rotatable with respect to the lift arm; a first hydraulic hose having a first end and a second end, wherein the first end is in fluid connection with a first hydraulic fitting in a fixed relation to the lift arm, and wherein the second end includes a quick connect hydraulic fitting and is coupled to a first mounting plate; a first bracket affixed to the lift arm; and a second bracket affixed to the implement attachment interface, wherein the first mounting plate is moveable between the first bracket and the second bracket, and wherein the first mounting plate is removably securable to the first bracket and the second bracket. ### Claim 2 (depends on 1) The lift arm of claim 1, wherein the first bracket is in a static relationship to the lift arm during rotation of the attachment assembly, and wherein the second bracket is in a rotational relationship to the lift arm during rotation of the attachment assembly. ### Claim 3 (depends on 1) The lift arm of claim 1, wherein the first mounting plate is slidably receivable by the first bracket and the second bracket without decoupling the first hydraulic hose from the first mounting plate. ### Claim 4 (depends on 1) The lift arm of claim 1, wherein the lift arm further comprises a second hydraulic hose having a third and fourth end, wherein the third end is in fluid connection with a second hydraulic fitting in a fixed relation to the lift arm, and wherein the fourth end includes a quick connect hydraulic fitting and is coupled to the first mounting plate. ### Claim 5 (depends on 4) The lift arm of claim 4, wherein the quick connect fitting of the first hydraulic hose is a hydraulic fluid supply fitting, and wherein the quick connect fitting of the second hydraulic hose is a hydraulic fluid return fitting. ### Claim 6 (depends on 4) The lift arm of claim 4, wherein the lift arm further comprises: a third hydraulic hose having a fifth end and a sixth end, wherein the fifth end is in fluid connection with a third hydraulic fitting in a fixed relation to the liftarm, and wherein the sixth end includes a quick connect hydraulic fitting and is coupled to a second mounting plate; a third bracket affixed to the lift arm; and a fourth bracket affixed to the implement attachment interface, wherein the second mounting plate is moveable between the third bracket and the fourth bracket, and wherein the second mounting plate is removably securable to the third bracket and the fourth bracket. ### Claim 7 (depends on 6) The lift arm of claim 6, wherein the second mounting plate is slidably receivable by the third bracket and the fourth bracket without decoupling the third hydraulic hose from the second mounting plate. ### Claim 8 (depends on 6) The lift arm of claim 6, wherein the third hydraulic hose is a case drain hose. ### Claim 9 A method of selectively securing hydraulic hoses of a vehicle during operation comprising the steps of: providing a vehicle having a lift arm, the lift arm having an implement attachment interface rotatable with respect to the lift arm; providing a first bracket on the lift arm, the first bracket configured to receive a mounting plate coupled to a first flexible hydraulic hose; providing a second bracket on the implement attachment interface, the second bracket configured to receive the mounting plate coupled to the first flexible hydraulic hose; and selectively securing the mounting plate and first hydraulic hose to the first bracket when a non-hydraulic implement is coupled to the implement attachment interface, and selectively securing the mounting plate and first hydraulic hose to the second bracket when a hydraulic implement is coupled to the implement attachment interface, and further coupling the first hydraulic hose to the hydraulic implement. ### Claim 10 (depends on 9) The method of claim 9, further comprising providing two J-shaped recesses on each of the first bracket and the second bracket, each two J-shaped recesses defining a protrusion therebetween. ### Claim 11 A kit for providing a multi-position coupling arrangement for a lift arm, wherein the lift arm includes a rotatable attachment assembly, the kit comprising: a first bracket and a second bracket, each bracket having a generally flat profile and two recesses defining a protrusion therebetween, each protrusion having a protrusion securement pin opening thereupon; and a mounting plate selectively securable to the first bracket and second bracket, wherein the mounting plate includes an annular opening having a diameter between 0.25 inches and 1.25 inches, and further includes a plate securement pin, wherein the plate securement pin opening and the protrusion securement pin opening are coaxially aligned when the mounting plate is secured to the first bracket or the second bracket. ### Claim 12 (depends on 11) The kit of claim 11, further including a securement pin. ### Claim 13 (depends on 11) The kit of claim 11, wherein the recesses are opposed J-shaped recesses. ### Claim 14 (depends on 11) The kit of claim 11, further including: a third bracket and a fourth bracket; and a second mounting plate selectively securable to the third bracket and fourth bracket, wherein the second mounting plate includes an annular hose opening, and further includes a plate opening for a securement pin, wherein the plate securement pin opening and the protrusion securement pin opening are coaxially aligned when the second mounting plate is secured to the third bracket or the fourth bracket. ### Claim 15 (depends on 14) The kit of claim 14, wherein the recesses are opposed J-shaped recesses. ### Claim 16 (depends on 11) The kit of claim 11, further including two hydraulic hoses. ### Claim 17 (depends on 11) The kit of claim 11, wherein the annular opening has a diameter between about 0.25 inches and about 1.25 inches.
