    Weak pump maybe. Pressure test it.

    Looks at the simple stuff first... how long has it been sinced you changed your fluid? what type of fluid did you replace it with? did you clean your screen at the same fluid change? Check your "quill" screw I know it will dictate how fast your plow falls but not sure if it effects how it raises?....all your electrical connections corrosion free and dielectric grease used? if all checks out, as stated above your pump might be going bad (if your angle rams are slow also but more likely then not you might have a syld/relay going bad)
