While changing my two hydraulic filters the oil seemed milky while ( seems like water from previous posts). 200 hrs on a 1999 unit that did some snow removal. I only have 10 minutes or so on the new filters to check for leaks with the old hydraulic oil. So my plan is new hydraulic oil and to just drain and re-use the newly installed filters. I have two questions, first on this tc-29 hydro unit do I drain two or three drain plugs and is it ok to reuse the two filters I just installed after draining them, My manual is for a gear driven unit, are the number of drain plugs the same ? Not sure about pulling the far rear plug. Thanks again looking forward to working the unit after all the maintenance..... Larry
