Seems like there's numerous manuals out there. I see these two on Ebay, and both seem to apply to my machine... ser. # 525218*** 2005 model. I'm guessing the numbers after the parts numbers are when the manual came out? One is part number 6902732 (2-06) 933 pages One is part number 6901828 (3-06) 726 pages I can't find any other manuals that aren't above my serial number range, so I'm guessing these two are the ones that apply. Anybody know which one I should get? http://www.ebay.com/itm/Bobcat-S175-S185-Turbo-High-Flow-Skid-Steer-Loader-Service-Manual-6902732-2-06-/330723517472 http://www.ebay.com/itm/Bobcat-S175-S185-Turbo-High-Flow-Skid-Steer-Loader-Service-Manual-6901828-3-06-/330723517461
