    Hello all,
    first off this is a neat site that I never thought i would find. keep up the good work guys. Ok a buddy of mine had an old western plow (1980) sitting out behind his garage that he no longer had any use for. It was just the plow and nothing else, no angle cylinders or mount. So what I did was since I have a bobcat with a quick-tach system for my attachments we made a mounting bracket out of some 3/8 steel and it works like a charm. My question is, since there are no hydraulics on it presently, and my bobcat has front aux. hydraulics, what cylinders and what kind of valve do I need to get? I think if I get replacement cylinders they are single acting? How about one double acting cylinder? What type of valve do I need- one spool ,2 way detent??? I dont really understand that type of lingo? Any help would be greatly appreciated. Thanks in advance.

    Since the Bobcat has Aux Hyd on the front you should be able to just plug hoses into the fittings and go.
    As for a cylinder, you could go either way with western replacement cylinders on each side or a dual acting cylinder on just one side.

    How about some pics.

    I will post some pics as soon as it done with the hydraulic end on things. As for the aux, its an older bobcat- i.e. its either on or off with a foot pedal- no control. That is why i need to put a control valve, i just dont understand what type. Thanks

    On/off huh, that kind of makes more work, might have to run a line to return to tank. Going to need to find out if its power in on one line and back to tank on the other, power on both lines, or will the one line be pressure with the other to tank and then flip when you go the other way. Depending on what it does you might not need any valving, just some flow restrictors to slow it down a bit.

    The aux run a backhoe, log splitter, which i believe one line is power and the other is a return. hope this helps

    That helps, since it will have constant pressure you will need to find a valve block that has a bypass in it. If you dont bypass, the machine will be deadheading pressure at the valve block and will burn out the hyd pump.

    Might want to look through Norhtern Tools site, otherwise someone will come along this evening and will know exactly where the valve that youneed is.

    I have a hydraulic block from a full hydraulic plow that was on my old Jeep. It was run off a belt driven pump but something like that would probably be ideal for you, even though you don't need the up and down function.

    Like Crash said, look in Northern and they'll probably have something that would be ideal, I assume you need a valve that can open pressure to one side and release it from the other, and then close both when there is no input on the control.

    also just a thought- my bobcat loader runs atf for fluid, is this okay for new cylinders?

    Ooohh! good idea!
    Doesn't that detent work on a spring loaded ball or something, couldn't you just remove that from the mechanism or is in internal?

    not sure the technical term. our bobcat has 2 way switches on the steering sticks. One way sends the fluid one way, the other sends it the other way.

    If yours is just one way, you need a valve to reverse flow.

    my loader is too old for that-just forward and reverse on the sticks

    yes, the hydraulic detent valve will work assuming you can mount it inside the cab easily and retain your heat.

    There is a diagram on there showing how log splitters work, click the button and it animates the valve.
