    I was debating whether or not to change the hydro oil from my ferris stander. Last time I did , it started leaking from the the seals and I had to have both pumps repaired which took about 3 weeks and was under warranty. No warranty this time. So I'm thinking about leaving it in there till it dies . Has 800 hours. What do you think?

    Unless there is contamination or it's burned I don't replace my fluid, only the filter. Fill the filter and then check the level afterwards.

    If it doesn't smell burnt and is clean maybe I change my hydros gear boxes every winter try and syphon it out if you have room to get tube to bottom

    i change mine at 500hrs as recommended. if you remove the filters in a john deere or a scag cheetah all the oil comes out anyways. there's no way around it. :laugh:

    so far i have 1400hrs on the deere hydros and they are still good. only have 800hrs on the cheetah and all is good.

    the only bummer is it costs $100 every time you change the hydro fluid and filters.

    There are exceptions to every rule but I have over 5000 hours on a Exmark lazer. Only changed the filter one time when it started leaking. That was after the 5000. Probably could use some new pumps. Think I got my monies worth:laugh:
