Does the plow lift cylinder need the weight of plow to lower?

    I am so totally new to pushing snow I have actually never done it. I have recently purchased what I have been told is a Fisher speedcast plow. Before I go spending a lot of money on push plates and truck side stuff, I wanted to know if my pump was any good. I hooked a battery up to the pump and it lifted but seems not to want to go down. Any beginning steps would help. Thanks ahead of time. Also if anyone would like to answer quite a few other questions I have about this plow, pump, and set-up, please feel free to call me. 540-359-1769. Name is Eric. Thanks.

    Thanks. I'm thinking of trying to find a shop that I can trust to set this whole thing up. I'd like to do it myself but am afraid of messing up the pump...

    the control would also need to be in float before you can push it down too.

    I take it float is the middle position? Or hold the joystick down? I found out today that in order to get push plates for my 1990 F250 xlt Lariat and this old speedcast plow, I am going to have to go to a welding shop and get them fabricated. I'm relying on the community here to give me what they think is a fair price. Any suggestions?

    it should go into float when you hold down for more than 1 second. then you can release it to the neutral position and it will still be in float.

    just like everyone said, you must be in float for the cylinder to move up/down freely. It does use the weight of the plow to lower, but not as much as you think. The internal valves within the pump assembly hold/control the fluid and pressure which directly control the plow. When you are in float mode, it allows the fluid within the lift cylinder to move in/out giving you the float mode, meaning the valve is allowing the fluid to move in both directions in/out of the cylinder.

    Thank you for the explanation. I'm sure other newbies will also benefit from it. How about testing the cylinders on the actual plow? Just hook em up and use the joystick?

    the angle cylinders? not too much to test really. all they do is fill with oil and that pushes the ram out. the seals keep the oil from leaking out around the ram. I'd just wait until you have it all together and run it. unless the rams are all rusty or something, then I'd replace the whole cylinder.

    That's what I was thinking. I wonder if he's related to birddseedd.
