    We have a MM1 V plow that we just changed the fluid on. Driving down the road with it straight the right side goes back to the v position by itself. The plow was fine before we changed the fluid. Any ideas?

    it could just have air in it if you haven't cycled through all the functions yet. if you've done that, then it's probably a piece of something holding a valve cartridge or cushion valve open.

    If possible... Try to hang the plow over an edge of something... So you can have the lift piston all the way down and be able to operate the V left and right etc.... This gets all the air out of the system. I was fighting with trapped air until someone suggested this and it worked within 5 or so cycles back n forth. I then had a solid plow. In the picture here the blade is not on the ground but the lift ram is bottomed out. Hope this helps.
