    My Lazer HP 23/52" has 245hrs on it. The hydro system is making a loud "thunking"?? noise and has a pronounced "shudder" when you make turns .
    I had the hydro system serviced but the problems persist. I've also noticed that the grabby shudder gets worse with use.

    Please give any suggestions you have.

    If I had to gues I'd say belt.

    I would recommend taking it to the dealer. Depending upon your s/n there may be an updated pump drive belt/spring.

    Look under the back of the mower at the hydro belt. You will probably see notches eaten out of it.
