Float issue

    I have been running the same Unimount plow since '91 and after numerous fabrications and repairs I finally decided to retire it and the current truck it was used on. This weekend I picked up a '99 Unimount STD. Got the '95 Tahoe wired today and hooked it up. It seems to work pretty well except that it doesn't seem to want to "float". When I lower the blade I should be able to push down the lift arm but I can't get it to budge.

    My other plow never had an issue like that. Any ideas?

    All other actions seem fine. Up and side to side, but the drop speed seems really fast.

    Also hold controller down while someone else pushes down the ram. Is there pitting on the ram?

    How fast does the plow drop on its own? Quill could be set to tight not allowing you to be able to push the ram down but the weight of plow can still pull it down. If it drops slowly I would bet the quill needs to be turned counter-clockwise a bit.

    No pitting on any cylinders, the plow has actually had very minimal use and stored inside. Cutting edge and shoes are in excellent shape and the P.O. swears they are original.

    The speed at which it drops is very fast.

    The quill needs to be turned in 1/4 turn till drop speed slows down. Screw on top of valve body.

    Does the float light come on on the controller? On my old meyer setup I would pretty much need to stand on the ram to get to go down to unhook the plow. With my xv the ram will go down by itself if left in float. Only few things can keep from going down by hand easily if the the valve is working properly. Quill, gland nut to tight, dirty valve. I would still try putting the plow down, leave it in float and turn the quill out a bit and try pushing the ram down. Just keep track of how many turns so you can put it back if you don't notice ant difference.

    Sounds good! I'll check out the quill adjustment.

    There is no "float light" on my controller. I got a hand held controller with this plow and switched it to my joystick controller to see if it was a controller issue and it did not make any difference.

    Thanks everyone!

    :drinkup:

    EDIT:
    I was just looking at the manual and according to that it appears I am blind as there is a float light next to the power light on the hand unit. Thats what I get for not wearing my specs.:rolleyes:

    I'm going to have to look at the controller again today. I don't recall seeing a float light on it, but the manual I was looking at(I downloaded from Western) shows it there.

    *But it also has a notation that some early editions did not have a float light.

    :confused: Gonna have to go look later when I get a minute.

    you do know you have to hold it down for like 1-2 seconds after it hits the ground, right? maybe it's going down so fast that you are letting off sooner.
    and sorry in advance if you already knew that, just checking!

    Well adjusting the quill about a 1/2 turn did wonders. Its still pretty tight but at least now I can get it move. I think the tightness now has to to with the packing around the ram.

    Oh, and my hand control does NOT have a float light on it so it must be an early edition as referenced in my downloaded manual.

    Thanks again for all the help guys! Much appreciated!! :drinkup:
