    Okay, I have yet another question about Boss V Plows. The driver's side wing seems to extend a little slower and weaker than the passenger's side wing when moved individually. It retracts fast, but I assume that's because the return spring helps. When moved simultainiously the passenger wing moves out quickly and almost completely while the driver's side barely moves. Once the passenger's side wing is almost out it stops and the driver's side wing moves faster and extends all the way out. Then the passenger's side wing finishes extending about 1 or 2 inches. Is this normal? Like I said even when moving individually the driver's side wing seems a little slower/weaker than the passenger's side.

    Differences in wing extend speeds are totally normal on a vee due to the priority circuitry in the valve manifold. One circuit will always flow a little more fluid volume by design than an another when connected by a common supply (the pump). And on a Boss, the right wing port is the first one in the circuit for the wing functions.

    what B&B said and the return spring tension can make a difference too.

    i had the same thing going on with my plow last year and someone told me to change the fluid i did and it did spead it up alittle bit but one wing is always slower than the other.

    Thanks everybody. Just want to make sure that we are all on the same page here. It's normal for the wings to have different extending speeds even when moved individually? Together I can see why since they are in a sense sharing the pressurized hydraulic oil.

    When run individually the left one is normally still slightly slower...but shouldn't be a great deal slower. Could have some debris on the screen on the left wing extend valve. Easy enough to pull it out and check it.

    Yeah it's not TOO different but noticable. It wouldn't be a bad idea to check out though just in case while I still have time. Where and how do I check this screen? Thanks again.

    The left wing extend valve is the one in the very bottom row on the underside of the manifold (facing down), it will be the furtherest most valve to the driver side.
