    The hydros in the walker mower hold a little less than a quart of oil each. They should be filled to the top of the plug on the top. The reservoir should have about 1/8" of oil in the bottom. That is it.

    Interesting point we have here......I have been meaning to email walker about this since the fall (have to before the spring). I bought what I needed (according to the maunual) to change all the fluids in the fall. I drained the hydros and went to fill with the 5w-30 that the manual says to use, and the sticker on the resevoir says to use 15w-50.. Since I already had the 5w-30 I used it. Thanks for the reminder......I am going to email them now. I will post back when I get the results.


    PS LawnPro in NC : I bought mine used and called Walker and they sent me the tractor manual, deck manual, and service manual for free. Give it a shot.

    mobile 1 15W-50 is the newest oil recomended. Go by the stickers, the owners manuals are not updated as often as nobody usually reads them. 5W-30 will not hurt your hydro if you already put it in.

    I don't have the manual with me, but I think it is every 1000 hrs or once per year, whichever comes first. But if you bought it used it is a good idea to change everything to avoid any questions. This way you are starting the season fresh and won't have to deal with it mid-season.

    As I said before....I called Walker and they sent me all the manuals I needed for free.
