Hi... I just purchased a used 24 ton Super High Output Commercial Duerr log splitter... serial #99-300-2785... I can not find a model # on the splitter anywhere... I need a manual - so that I can order parts that are needed... if anyone can help me with this I would greatly appreciate it... thank you

Try this company for a download. The manual in the picture is not yours but you should be able to use this site to get the correct one.

Hi, Duerr was bought years ago by MTD so you try ManualsOnline at:
Free MTD Log Splitter User Manuals | ManualsOnline.com (http://lawnandgarden.manualsonline.com/manuals/mfg/mtd/mtd_log_splitter_product_list.html)
Or eReplacementParts at:

Peace,
