    I have an older 6 1/2 foot plow on my 89 ranger. It has cable operated controls and the frame and motor stay on the truck. It worked fine on Tuesday, now it wont do anything.
    When I pull the lever, I can hear the motor spinning like its trying to pump, but it wont move. I checked the fluid, it was full. I usually put it in a garage overnight, but didn't last night, that's the only thing that changed.

    If it's real cold there may be moisture in your fluid plugging sump screen (fluid pickup). Get it in warm shop for a few hours, drain the fluid into clear container to see water in the fluid. Replace with fresh and try again. Use blue fluid if u can. Not auto trans fluid.

    These old cable plows did have a sticker that says to use ATF and because of the large valve orifices, so I am told, they will run fine; however, when they made these units the blue fluid had not been invented yet. On my Western course they said to use the blue aircraft plow fluid in all plows because it has a stable viscosity at a very wide temperature range. But it's up to you, if you have ATF you can use it. But you will find the plow runs slower when the temp dips very low.

    I jacked up the plow and chained it to bring it in, and noticed something funny. I could angle the plow by hand almost all the way, almost like the angle cylinders have just air in them. When i conneced each cylinder to each other, i could swing the plow all the way by hand as expected. The wierd thing is the lify cylinder is holding at 1/2 way down. I can put it down with the control, then when i lift the lever it will stop. It wont come back up though.
    Ill see how it is in hte morning.

    Sounds like you may have some cable to valve linkage adjustment issues. Maybe the angle valve is staying open allowing fluid to move freely. It is normal for the blade to move if you connect the rams to each other, the fluid just shifts from ram to ram.

    truck warmed up in the garage, and it works fine now. I cant angle the plow by hand anymore eather(unless the 2 cylinders are hooked together)
    It was wierd but at least it was afree fix. Next time it snows ill just put it in the garage the night before.

    If you have water in the valve body where the cables hookup then when it freezes it won't allow the cable to move. Pretty common unless the cable entrance is sealed with silicone.

    That's common then you get mad and push on the stick to much and break the cable clips on the bottom of the box

    ahh yes, good point western1 dude. you can also fill those cavities under the covers with grease so the water has no place to sit in there.

    Thanks for the help...one more question, how tight is the big nut around the lift cylinder supposed to be. mine was only finger tight so i snugged it s little with a channel lock

    That plow uses a packing nut meaning the tighter the nut the tighter the seal pushes on the ram. Too tight and it will bind, too loose and it will leak. Unlike the new ones that r torqued to specific ft/lbs. maybe one of the old timers can tell u a torque spec.

    OK, Snug engough should be good enough then. It doesnt leak like crazy, just a small weep when i park it overnight wiht the plow up. Thanks

    yea, it says 'not more than 1/4 turn after you feel the packing nut contact the packings. over tightening affects cylinder operation and packing life.'
