    Hello All-
    I am fairly new to this plow..picked it up used last year. it worked very well last season. i went to hook it up this year...filled fluid...tank was low....ran it through its positions and topped off the tank. After a few more cycles of the positions, the left side cylinder stopped working. now the plow is locked in left position...all other functions work..wings..up and down..but i cant get it to move to the right....i can see any evident leaks so was hoping some of you may have some thoughts....i did push the right side against a tree while operating the joystick to the right in the hopes that i could get it to release and stay straight so i could travel with it..but as soon as i backed off the tree, the blade pushed back to the left side.
    Question 1 do these cylinders operate with some type of relief valve?...they appear to only have one hose to the cylinder so i dont understand why it would spring back left when it was straight and i operated the joy stick which i think should have released pressure on the right side cylinder

    Question 2 might there be a test proceedure to follow to narrow it down to the actual issue...

    Any help would be appreciated

    Also check your plow to truck connection I have had some corrosion and it stopped my plow from moving while the pump would run.
