Smart Hitch 2 Problem

    Hey everyone. I've been having a little problem with unmounting my plow, 8' SD probably 4-5 years old. When I try to power down the tower the motor seems to run but it does not power down the tower. If I let it, it will slowly move down by itself or you can manually pull it down, but I usually keep the button pushed as this is what I've read in other threads to keep air out of the system... could it be the switch itself is going bad?

    Also, sometimes when I go to hitch it up I push the button up and the motor will run but it does not move. Pushing the button down for a second and then back up it works just fine. Any thoughts?

    Thanks in advance for your input and help!

    Does the plow work perfectly when it's actually on the truck?

    Yes, no problems at all. Last season when it was really cold out it was extremely sloooow... I changed the fluid and that took care of that. I think the previous owner put tranny fluid in it. But yes, once it is hooked up it works just fine.

    Your tower raising issue is likely the SH toggle dying but that won't affect the action of powering it down. Since for it to power down all it has to do is run the motor with the controller in the float position, which it does. Sounds more like there's too much tension between the truck and plow while you're attempting to detach. A dab of grease on the receiver hooks helps too.

    I also have the same problem with one of mine. I have to toggle the sh switch really fast, sometimes six or seven tries to get the tower to jump forward and unlock then it will power down.

    Your issue may be a bit different in that yours could be a mechanical issue. Dry pins, broken pin retract spring, plow or truck off camber, or a miss adjusted mount.

    it could be different, ill give you the whole story;
    i drive in to the plow float on, make electrical connections, turn levers to on, toggle up and the motor sounds like its stalled out, like when you pick the plow up and keep the up button on, sometimes i get a spark at the coupler bottom between the saddles or the cradle or hook or whatever its called. if i toggle up and down fast with the switch,the motor will start and raise the tower up.

    Pretty sure sparks at the frame means your ground connection is bad.

    Needs either the switch replaced (usually the case) or the connections on it as well as the leads from it to the smart hitch coil cleaned/tightened. Easy fix.

    Sparking at the mount is a poor ground connection between the plow and truck through the power cables as the Dog Napper already mentioned. Needs a good clean and tightening there too.

    i figured id probably need a switch, all the connections/wires to the switch are good ive used dielectric grease on them when i serviced it in oct.

    thanks to all

    Nothing wrong with the hydro's, it's an electrical issue. :waving:
