    Howdy all!
    I'll just cut right to the chase....
    I've got a 44" Zturn (mdl# LHP4420KC) with a Kohler engine that is spitting hydro fluid from the vented cap on the reservoir.
    The operator says it starts leaking after about 10 minutes of use. the reservoir is not overfull, and I don't think there's any air in the system (not foamy)
    any ideas what else it could be? :dizzy:

    I swapped on a new filter, and ran it up on blocks with the controls full forward for about 20 minutes, and it seems fine! I'll send it back to him tomorrow.
    the funny thing is...he called and said that the spare I sent (44" exmark with a Kawasucky) was doing the same thing. only this time, there's no power getting to the right wheel, as well as the leak from the reservoir. :laugh:
