hydraulic cylendar

    My old lift cylendar was siezed up this year so I bought another one. However it acts different than the old one. There is a short delay when raising the plow. Once the engine is turned off and the plow is resting on the ground, I can easily push the ram in the rest of the way. A couple inches down, it feels like it hits something but continues to go down easily. I can also pull it back out with one hand. With my old cylendar, I had to put my whole weight on it to make it go down. This is only the first cylendar after the original, so I don't know which one of them is normal. Just wondering if I should take the new one back before I use it. Any ideas?

    Air in the cylinder? I'm just taking a stab in the dark.

    Sounds a little strange. Yes, could be trapped air... I assume you have cycled the plow in all directions since this has happened.

    My Hiniker has a packing nut on the lift cylinder. (threaded end of cylinder) In order to dismount the plow you have to manually step on the lift cylinder foot pedal to compress when the blade is in the float position. Here is an excerpt from the manual:

    NOTE: The plow control box must be in the "float" mode to move the cylinder rod. If the cylinder rod does not retract with power on and the controller in float, loosen the packing nut on the lift cylinder up to 1 1/2 turns to reduce friction.

    Something you could try.

    Sounds like air, cycle the piston a few times and see what happens.
