I built a loader for a 4110 which is a size larger than the 317 - 318 series and has four wheel drive. No plans, just built as I went off photos of like machines. With four rams, lines, hoses, steel, and pins it was less than $800 including the 53" quick tach bucket. The internal hydraulic pump is more than adequate. Fun project. Also made a PTO vacuum for grass and pine needles. Total cost $75.00 with scrap steel and free blower housing.
