    Is anyone else having problems with the hydro pumps on ZD 18 or 21s? It has happened to me on two machines both on the right side. It has also happened to other mowers in my area (Northern Vermont). Symptems are sluggish controls, skidding, jerky wheel movement getting off a trailer or especially on a hill. One dealer has been replacing pumps-mine is suggesting adjusting the control linkage.
    Please let me know if anyone is experiencing these issues and if so, what is your dealer doing for you?

    At 200 hrs my old zd18 had the whole hydro unit replaced.(same symptoms) .It's a known problem
    with the early kubotas and they replaced mine and extended the warranty to 4 years.
    Your dealer should know this!Don't let him shuck and jive you about it!

    I saw the memo from Kubota with my own eyes when they replaced mine. Never gave me another problem after that.
