Husqvarna CZ4817 zero turn mower..
The right side hydro pump is whining and weak.. too weak to use!
Are these tubes on the pics the fill valves to top off HYDRO FLUID to the pumps?

Those are the vent tubes for the hydro. There is no way of telling how much oil is in the unit without dumping it out and measuring it. the correct amount is no way near the top of the hydro unit.

A loud whining noise could be a hydro that is toast or maybe just a stuck parking brake. A loud growling noise is almost always a toasted hydro

Well that confirms my suspicion, I figured it was a toasted Hydro pump on the right side.. Its just like you said "growling noises" coming from the unit (especially when its in full throttle).


The hydro is almost completely useless, its nearly impossible to operate the mower. I was hoping that when i bought it yesterday that the guy was right about "just needing tracking adjustments" but I guess I got Goosed!

-Thanks for the input, i'll see what I can get for the unit as-is! Maybe I can atleast recoop my $400 for it!:thumbdown:
