    I just got a lazer z with 350 hours on it, if you push both levers forward it will go to the left, the right side is faster then the left. seems like an adjustment, the last exmark zero i used did the same thing. from reading people are saying bad motor or pump, this thing has plenty of power and I do not suspect a weak pump.
    any help would be nice.

    My manual has a motion control linkage adjustment but its more to set the lever in neutral.

    Matt....first make sure both your rear tires have the same air pressure..
    To adjust the tracking...adjust the rods from the handles to the pumps..
    Speed up....lengthen...... the rod on the slower side..

    was mowing today and noticed a couple things. the right side, when pulled out from neutral goes forward on its own, the shock pushes it. not sure if this is adjustable. also the left side, witch is slower has an inch of play before any hydraulic movement happens. but the right side has very little play.

    It's fairly common for the pump control arm to develop some loosness/play on the pump shaft--check to see if the pump arms are properly positioned on the flats of the pump shaft and tightened properly. With that aspect checked, follow Slappers instructions to adjust the linkage for proper tracking.

    If the lever goes forward by itself...the valve in the dampner is bad...replace it..
    If you're not getting positive movement when you engage the lever..tighten the arm on the pump...it is loose..

    Thanks for the help. I tightened up the left side, it was loose. Its better, I tried tweaking the rods, got it pretty good but left is still a little slower if i went any more with the left it started creeping in reverse with the brake on, a lot better then it was tho. I have 2 new dampers I am going to install.

    Ill keep you posted, again thanks for the help. This is my first zero turn.
