    Worked fine for 1st week of heavy plowing this year. Now all of the sudden it's "whining" kind of loud as it moves, and moves way slower. Topped off the fluid thinking it may have been low..which it was. That didn't do much.
    Could the lines possibly have air in them?? Any advice is good advice!

    Thanks

    Check the poppet assembly in the side of the valve block. Occasionally they get stuck, or cocked in the adjoining passage causing reduced hydraulic pressure.

    See assembly "D" on page 1 here:

    not sure what pump you have, but it is likely your filter needs to be cleaned. pull the motor, then the pump, then clean the filter. if you haven't changed your fluid in the past year, its probably a good idea to do it now.

    Sounds like a bearing noise??

    do you have a "uni ,mount" or a "uttra mount"?

    If the loud sound is from the motor, one would seem you need another motor. Before you make a decision to replace the motor, bench test the motor. Take the motor off the pump. (use your battery for this test), with jumper cables, connect the pos n neg to the battery. connect the positive cable to the positive terminal on the motor. then ground the motor. If you hear that low noise, replace the motor. If not, the pump is causing the problem.

    Here the setup for the "untra mount"

    Setup for "Uni Mount"
