    That can't be normal.

    I now notice that my machine is pulling to the left, I’m wondering about the final drive motor may be going. Tried the water separator bypass and still dogging up grades.
    Any other suggestions before it goes to the dealer?

    Want to make sure I’ve installed the inline filter properly! Is the fuel “IN” the seperator on the left and “OUT” on the right? Thanks, I’m having a brain fart.

    So when I plunge into dirt, it bogs down under load, takes a second to lift up, then pulls the load. Hmm, I’ve gone direct with the filter, bypassing the water separator. Any ideas?

    Do you get a lot of black smoke when it struggles? Have you removed the oil fill cap to check for blowby? You changed air filters?

    I have changed every filter and all fluids on the machine. How do I check for blowby? There is zero black smoke and the engine runs strong. Thanks for answering!

    just remove the oil cap with the engine running. You shouldn't see a lot of 'air' coming out. You say it runs strong but it bogs down going uphill? Contradiction there

    The rpms stay up, but the machine just slows down. I'll check for blowby. Should it be heavy rpm?

    Its basically losing power, doesnt sputter or anything.

    There is no blowby.

    So the rpms don't drop going uphill?
    What type of hydraulic fluid did you put in?

    Kubota hydraulic oil ISO 46. It just keeps making motor noise, but no power. Almost stops on a 10 degree slope, full throttle.

    if it was fuel related, wouldn't it sputter? It's good clean fuel.

    Ok. It sounds to me like you have a hydraulic issue. Either worn pumps or drive motors. Maybe that's why the machine got sent to auction.

    I'd think the next step is to test the hydraulic pump pressure. Not sure how many pumps your machine has. Maybe it has a dedicated pump for the drives. If you don't have gauges, then you'll have to take machine to dealer or someone.

    6F5D12A9-BF1D-41FE-A884-4F77194B122F.jpeg That white plug under the black box was unplugged for some reason, not sure what it does or why it was unplugged. I ran it after and no change. Took a video of what the machine is doing. How do you post a video? Thanks
