FIG. 5 shows the relationship between: the tine standoff 124 and the buck rail 126; and the alignment apertures 146, of the constraint structure 110, with the confinement pin 134.

FIG. 6 shows a flow chart 200, of a method of making a skid loader attachment, such as 100. The method steps begin with start step 202 and continue with process step 204, where a universal mounting structure, such as 102, is provided. At process step 206, a pair of slide shaft support flanges, such as 104, are secured to the universal mounting structure, preferably at a proximal end 106 of the universal mounting structure, while at process step 208, a slide shaft such as 108 is attached to the pair of slide shaft support flanges.

The process continues at process step 210, with the securement of a tine adjustment structure, such as 110, to the distal end 112 of the universal mounting structure. Preferably, the tine adjustment structure protrudes horizontally from the universal mounting structure. At process step 212, at least one tine, such as 114, is constrained in sliding communication with the slide shaft. Preferably, a pair of constraint structures, such as 116 (which preferably cooperate with the tine adjustment structures and support a pair of tine standoffs, such as 124) are fastened to the at least one tine at process step 214. Preferably, the tine standoffs are in sliding, contact adjacency with a buck rail, such as 126. At process step 216, a tine support structure, such as 120 (which in a preferred embodiment includes a slide shaft bushing, such as 122, mounting for sliding communication with the slide shaft), is fastened to the at least one tine, and a shaft support structure, such as 118, is secured to the universal mounting structure at process step 218.

Continuing at process step 220, a load restraint, such as 128, is secured to the pair of slide shaft support flanges, and a shackle, such as 130, is secured to the load restraint at process step 222. At process step 224, a fixed slide shaft restraint, such as 142, is secured to a first of the pair of slide shaft support flanges, while a removable slide shaft restraint, such as 144, is secured to the second of the pair of slide shaft flanges at process step 226. At process step 228, a confinement pin frame, such as 132, is secured to the tine. At process step 230, a confinement pin, such as 134, is captured within the confinement pin frame, and a retention flange, such as 136, is attached to the confinement pin at process step 232. At process step 234, a force member, such as 138, is disposed within the confinement pin frame such that it surrounds the confinement pin, and the process concludes at end process step 236.
