    I like my plow, my customers, and knowing that my plow works properly, so yes, I change it yearly. It's a small price to pay for piece of mind!

    Get the fluid changed or the wood you will be knocking on will be the handle to a snow shovel.

    Systems should be flushed and filled every fall, and doing it in the spring after the season doesnt count. Condensation builds up in the system with the tempature changes of the sesaons and thats why you get frozen pumps.

    This thread is a good reminder. I'm guilty of not changing mine in atleast 3 yrs..maybe more:gunsfiring: For how inexpensive it is to do verses big repairs.

    I'm doing mine tomorrow.

    Preventitive maintenance is the only way to go. I'd rather change the fluid in my nice warm garage once a year, then be messing with the pump when its 10 degrees and 8' of snow on the ground trying to figure out why my pump won't work and I'm losing customers by the minute.

    I didn't the first 3 seasons I owned mine because I didn't know better. It always worked fine--but once I got wise I started doing it every fall. I generally flush out all the old stuff and add fresh, plus put a new filter on the return line. Takes all of 30 minutes.

    I think I'd be sitting at home if there was 8 feet of snow. Or I'd be looking for a helicopter to rent so I could clear my driveway and get out.

    in one word NO

    the reason is because there is nothin wrong with it (the fluid),

    we have some older heavy equipment that i have never changed the hyro fluid in and i have owned the machines for at least 10yrs

    and other than that i just never think about it.

    I bet on that older equipment there is not a sticker or a manual saying to change your hydraulic fluid annually (that means yearly;)) on it is there?

    I never change mine. Meyer E60 , 15 years old never changed and works perfect. Other plows are 10,4, and new, never changed.

    Same here. Why open up a system to a world of hurt. If you open a hydraulic system to change you fluids you must flush the system out. All the toys I have only been opened up for servicing the system. Once your hydraulic system has been compromise. You should flush the system clean, replace filter, and bleed your system out. Then don't open it up until the next repair. Hydraulic systems are very reliable if your maintenance habits are A+.

    Your system is compromised every time you use it.
    It is not sealed

    Your reservoir has a vent.
    Every time you move your plow the fluid level changes.
    Air is ether drawn in or pushed out.
    When this happens the hydraulic fluid has a chance to absorb moisture.

    Storing your plow in a heated garage between plowing leads to condensation = more weater in your fluid

    I just had some problems with my back-up truck which is a 1988 GMC with a Western Pro blade on it. Conventional style from 87/88.

    It was the original filter and fluid.

    Well bottom fluid. I had never done it and neither did the school district that owned the truck before I did. You could tell it was the 1st time the motor was off as the spray painted gasket edges told me. There was some sludge in it but not as much as i would have thought at the 20 year mark.

    It has had a connection failure and hose burst on it so I have added fluid to it. But I am the believer of if it ain't broke, don't fix it. As far as pumps go.

    I take care of the truck with good maintenance otherwise but for whatever reason i just never messed with the pump. It still worked and the problem turned out to be only a cable adjustment. I could have left the old filter and fluid in and still have a working plow.

    Never froze up and lifts at the same speed it always has. I don't recommend this for anybody and I have serviced my Boss plow which is my main truck.

    For some reason though on that old western it just sits and if I drive it 300 miles a year it is a lot. As long as it worked when I got in it I didn't much think about it.

    Pic of inside after it's 1st lifetime flush.


    Old gasket on left. Original. You can see the filter in the background was still usable.
