    I am going to be buying a Fisher MMII 8'HD plow hopefully this weekend. It is used, 2005 model plow. My question is- how hard is it to change the hydraulic fluid in the plow? Is it something I can do myself before the season, or should I have the dealer do it while they're mounting it to my truck? Also- how hard is it to get to the fluid filter and how often does it need to be cleaned?

    It's not real hard to do. Get on the INTERNET site for the plow manufacturer.They should have a down loadable manual for the plow. With what they will charge you to mount the plow they would change the fluid. But, I have seen installers not even fix bad wire connectors. Do a search using the function on the gray line above. It's been asked many times before I am sure.

    Yes this is something you can do on your own. Very simple.

    1/2" Wrench and 1/4" hex. First take the 1/2" square nut out of the side of the tank. To let air in. Then take the bottom hex bolt out. Takes a whooping 10 mins to change the fluid.
