    Hey guys I've got an issue with my plow and I don't know whats going on with it.

    It is a new plow-about a year and a half old only a few storms on it

    While out during the last storm my plow kept going into a 'seizure mode'

    Usually it would happen mid-way through cleaning out a driveway or parking lot.
    The motor would sound like it became locked on. The hydraulics would tense up and the noise would persist until I angled the plow up/down/left/right. When moving the blade the noise would stop. Sometimes I would joggle the blade around and I could get the noise to stop. Other times it wouldn't stop and I would have to unplug it. One of the tips on the plug was getting hot.

    I'm not new to plowing though I am new to this issue. I don't know what to do or what is going on or what to do about it.

    Any help would be greatly appreciated!
    Thank you,

    Start with cleaning and checking all your electrical connections.

    Well it sounds like the motor is getting stuck on, so first step is to replace the solenoid
  4. Agree...sounds like a bad solenoid.
