    8' MM2 with a fish-stick control

    I have used the joystick mount control before with a electric MM2 & never experienced this before.

    I hit the button for angle & release it & the damn blade keeps on going, long after I release the angle button.

    I am talking it adds about 15-20 degrees more into my angle. To get around that I just bump start it. But it sure is a pain in the Butt.

    Is this normal? I have this same problem with two of the trucks I have used, so I take it, this is normal.

    Any good advice or info on this would be appreciated.

    i notice when im plowing if i angle the blade in the middle of a push the blade will go to full angle. im thinking that with all the pressure on the blade if its a good amount of snow or heavy snow, when you open that solenoid to angle its going to keep pushing under the pressure. ive never had the plow continue to angle with no load on it. i also have a fish-stik. not sure if its in the electronics to do that or not, but i agree i dont like it when it happens. if i want full angle ill hold the button down!

    Yeah, & I am talking while the blade is up without pushing snow. It is worse when pushing snow.

    Thanks for your reply!

    It's totally normal...

    What your experiencing is the "smooth stop" feature that's built into the hand help controllers.. many of the plow manufactures added this feature to them now... it allows the blade to come to a smooth stop rather than banging and jerking when you let off the button..

    Many guys that have used a joy stick style control for years and then switch over to a hand held with the smooth stop feature find them a bit hard to get used too...

    That is madd annoying ! My older Meyer E-60 with the touch pad would do that. I couldn't deal with it... I need positive blade movement.

    I Thank-You for your response, I was feeling that it was something with the hand held, but now I know for sure. Although, I did find out that I had a leaky angle line on top of that when I ran out of fluid near the end of the day.

    I rather like the joy stick style better, a more positive feel is more my style. But it isn't my truck or plow, I am just a sub for the company. So, I'll get more familiar with it as time goes on.

    i guess another thing you might look at is your relief valves? possible they are stuck or not functioning properly. i think thats the problem with mine as it continues to angle only when there is moderate pressure on the board and i angle it. yours maybe a little further along than that? not sure but its an idea. i get the whole "smooth stop" feature but a smooth stop is one thing. going to full angle is another. mine adds approx. 5 degrees - MAYBE 10 at the max when i release the button and the plow is raised and not pushing anything.

    Based on what you said, I'd bet you lunch your selenoid is sticking. Go get yourself a new one... I think they cost $22

    Do you mean the under hood motor solenoid?

    That can't cause a MM2 to continue to move (not on a straight blade anyway) as the pump can run all it wants after you let go of the button and it still wouldn't move the blade...It needs a valve open to move..
    If a valve isn't open, the blade can't move... motor running or not...



    Because the controller is controlling the valves on the pump also... and it's the open valve after you let go of the button that makes them continue to move because the smooth stop in the controller holds the valve open for a sec or 2...

    Now on the V's if you have a sticking motor solenoid, it will retract the right wing since it uses no valve for that function...just the motor running.
