I bought a 2-stage snow blower (think it's a B222, no ID tag) and when it's all hooked up, the hydraulics won't lift it. Granted it's a heavy SOB, but one I had the singe stage it would do it no problem. With the single stage it had 1 lever control valve, and when bought the 2-stage PO lifted it with the 3 point hitch circuit. i'm not sure if it's too much to lift with the control valve or pump or cylinder is worn out. Thought it was low on fluid but it's fine....
