Lag on lift

    I went out last night and was having some intermitant problems with the plow lagging on lift. I'll hit the joystick to raise it, the motor will run for a second, then the plow will lift. It seems like the motor is running with no restriction until it runs for a second and starts to lift. It did it for a bit, so I stopped and checked the fluid, topped it off (wasn't really low), and it worked fine for a few tests then started doing it again. I just put in the new lift ram seals and changed the fluid, but I think it did it before that. I'm not sure becuase it's intermitant and I haven't really used this plow before. Any ideas?

    Recheck your fluid level, might have burped out some air:drinkup:

    I should have mentioned, but I checked it a couple times. I think I repeated this process 3 or 4 times last night, and I was just out on a work-out-the-bugs run.

    if the fluid is ok, then i would look at your cable connections (special attention to the grounds) if you have a bad ground, it will act the way you are describing. if cables check out ok I would assume pump gears are going. JMO

    Are you sure that its not because the lift cylinder is collapsing fully and it just has to take up the slack in the chain before it lifts the blade?

    umm, is this a unimount? or ultra?

    if its an ultra have you checked the filter to see if it fell off...common problem

    Forgot that too: it's a unimount.

    Crash935 - it's like that's what's happening, but that isn't happening. The lift ram isn't going all the way down (because of the slack in the chain), but the pump/motor is acting like it is.
