    No hose clamps. No inspection or changes.

    Running out of aces...
    If the hydrolever is tight to the pump shaft ...
    Could be a defective pump...They are assembled by people...
    Sticking relief valve...????

    On the small hose coming out the side of the pump it has a plastic yellow band that I can move around a little and can actually turn the hose on the fitting. Is this normal?

    I would remove the band and put hose clamps on all the bypass hose connections..

    Your mower is giving you an education you couldnt get in a classroom or reading a manual..
    Hang in there...

    How would I check the relief valve?

    Re read the whole thread...
    Its sounding like you have a collapsed hose...maybe separated inside..
    Might be a piece of metal stuck inside one of the hoses or fittings...
    Maybe a plugged tank..something doesn't add...
    You have changed the pump and wheelmotor and the problem remains...

    I agree. I have a new high pressure hose coming in for the one I didn't replace as it all brittle on the outside and since I already changed one figure I'll do the other too. I will go through everything first chance I get. Probably won't be till the weekend, have about 50 lawns to do to finish this week.

    I'll update once I have some news.

    Thanks again.

    Greg...check all the low pressure hoses and fittings for obstructions..
    These supply fluid to the pumps...
    On Dixie Choppers...they use the same pumps...when a pump starts shredding parts..the small hose going to the wheelmotor usually gets clogged with pieces of metal..
    If you still have the old pump..take it apart and see what's missing..
