E60 won't lower -----

    What would cause an E60 to get "stuck" in the Full Upward position?

    Everything works properly. It's just that sometimes (only when the blade is ALL THE WAY UP) it won't lower. It will eventually lower, but only after power cycling the controller, and just waiting.

    When it does get "stuck", and you try to lower it, the controller seems to think everything's ok - even thinking it's in Float.

    It doesn't happen all the time, AND, it NEVER happens if the blade is only part-way up.

    (it's a Classic Mount on an 02 F250/diesel)

    Likely a mechanical issue. Bent ram, worn ram guide or worn lift arm/pivots causing incorrect (over center) geometry. Second possibility would be a weak A coil or sticking A valve when there's max pressure in the lift ram.

    Next time it gets stuck remove the A coil and SLOWLY loosen the A valve a few turns until fluid begins to leak out around the valve base. Does the plow now lower as it does? If so, then it's an A valve issue. If it still doesn't, then it's a mechanical (binding) issue.

    BB, thanks for your help.

    Will it help to ID the problem if I tell you that I ran this E60 on my previous set-up last year.
    I was finishing up a driveway one night --- when I went to raise the blade, the motor fired, and the blade started to raise, only it would not hold. It just fell as soon as I let go of the button. I got it home and found (I think) a bad a ground to the coil. Cleaned the grounding surface and was up and running....
    Could the problems be related? Would a coil or valve replacement remedy the problem?
    (I've been up and down the manual, front and back....)

    A bad ground to the A coil? There is no ground on the coils, they're grounded through the valve they set on. But regardless a poor ground wouldn't cause it to drop on it own anyway, thats a stuck A valve...which definitely could be related to your current condition (hint hint :D).

    If you do change the A valve and or coil be sure to get the round coil not the square one (if that's what you currently have) as the square ones had and created all sorts of issues.

    In your case it's likely a plugged A valve. Even though the valves have a scree on them the fine stuff still gets through and after enough time can restrict the internal valve spool.

    I just found one online for like $34. I think I'm gonna replace it - seems cheap enough.
