Kubota ZG help!

[parrithead]

I have a ZG222. It is about 3 1/2 years old with around 120 hours on the meter. Problem is that it seems like only the left control arm is working. The right arm will control, but i would guess it to be at maybe 10% of what it used to be. I know that this unit only uses 1 hydro, but do not truly understand how it works. I checked all of the fluids and they are fine. I had changed the hydro fluid at 50 hrs as a precaution. The unit is greased very 4-5 hours. I have not had any issues at all with the mower. Has anyone else has a similar problem? Or maybe can shed some light on my issue or a least point me in the right direction.

Thanks

Maybe the linkage has come loose or something. What kind of warranty do you have, it should be covered if you are still in warranty.

I have a zg222 bought new in 2009 now has 500+ hours. It's working great! Is either if the sticks more limp/looser than the other?

Not sure about the warranty? Its almost 4 years old. The sticks are tight, both about the same. Just seems that the right one doesnt control?

Is the control arm on the transmission retained by the means of a roll pin? If so, you may have a broken roll pin.

Just a shot in the dark from looking at one of the ZG222's on Kubota's website.
