Have sufficient drain pans to hold the fluid you drain. Advanced Auto Parts has a 5 gallon drain pan (yellow plastic with a spout that has a cap on it) that worked for me. I used 2 of them. Removed the front most plug which almost filled one pan, removed the other ones which half filled the second drain pan. I then refilled the system and poured all the used fluid back into the 5 gallon container (I used Amsoil) plus several 1 gallon milk containers, took all of them back to Advanced Auto Parts and poured it all into their oil recycling container. I now use the 5 gallon can to hold oil changes from my other vehicles.
Removing the tool box makes it easier to pour hydraulic fluid back in from a 5 gallon can.
If you live in a cold climate, replace the standard hyd fluid with the NH F200 fluid (I think this is the number) or use a synthetic like Amsoil. Makes the hydrualics much quieter in freezing temps.
<font color="blue">I see the part nos. have changed for other models, is this the case with the 29. Does anyone have the proper nos. handy?</font>
I just visit the dealer and ask for the filters for my tractor (TC25D). /forums/images/graemlins/cool.gif
<font color="blue">Should I fill the filters (hyd, fuel) before putting back on? </font>
Yes, particularly the fuel filter. Fill it to overflowing that way you shouldn't have to bleed the fuel system when you are done.
