Boss Plow won't go on and off truck hydraulically

    Does anyone have this problem or have a fix for my Boss Plow? The plow will not go on and off hydraulically. I have to use a 2x4 to put it on and off my truck. The remote does seem to enter the program and it allows me to put the plow on using the 2x4.

    All other plow operations work fine.

    Any advice?

    Thank you,

    Jeff

    we had this once, was the wire harness, some of the couplers corroded and broke.
    not sure if thats the only thing that can cause that, but sounds like it.
    i would check that - its pretty common on most plows

    Sounds like your cutting edge is getting worn out.

    cuuting edge

    What would the cutting edge have to do with the going on abd off hydrolically?

    When the cutting edge is worn and you try and take it off by using the switch the hooks on the plow will get hung up. Because you are saying you are using a 2x 4 to get it off and on.

    When I am removing the plow it is set on snowmobile dollys so it is off the ground an inch and a half.So it is not sitting on the ground.Is there a spec for the wear bar? The pow is 8 years old but it looks like new yet.If I block the blade up higher it could possible come off hydrolically

    make sure its in float
    check your plug for broken posts
    all wires conected right (should be a wire diagram on fluid tank)
    might be a bad smart hitch switch

    What exactly do you mean by the remote is switching?Are you talking about your tower on/off toggle switch making the pump run but yet it won't raise the tower?

    Yes I know that. I have had the plow foe eight years. Just took plow off,tried something new,pushed up on plow to release lock pinsand it will hydrolically will come off.Problem is I can heaer the pump working to go up to release the lock pins but it does not move.so, the pump is rinning but not pushing fluif in the right direction.Pump sounds like the valve is closed so the pump can notmove the cylinder up to release the lock pins.

    u might have a bad coil take the down coil off stick a screwdriver in the hole and have someone hit the down button, see if its magnitized if not then bad coil if it is then check the valve take that out put coil on the valve post (disconnect main power and ground wires so pump wont run) theres little holes for the valve whatch in there to see if they open u can also hear them move hope this helps let us know!

    the light switches from green to red,so its in float position,that is when the switch on the plow works for putting plow on and off. jeff
