    We have a Zipper mower that my dad uses at his place. Last time I used it, I noticed the hydros getting rather loud. The more load on the hydro system, the louder it is. From experience in hydraulics, it sounds like cavatation from either a blockage in the intake or air getting in the system.

    Never the less, I am curious if anyone else has experienced this and what was required to fix it?
