    In my research of hydro system problems,I've seen "hydro pressure spikes" mentioned as the most common cause for failures,,so how do you get a "spike", what causes them, and most important what does Exmark recomend to avoid the spikes?

    You may want to take a look at the following thread.


    Pressure spikes are going to occur in any hydro drive system. The real trick to keeping them manageable is managing the operator input to the controls. To a degree it's a little like an automobile. If very time you move forward you stomp on the accelerator you try to push it through the floor your probably going to wear driveline components. If you also then stop the automobile in the same manner youÂ’re probably going to wear the brakes faster.

    You can add transmission coolers, larger brakes use different materials etc. to reduce the wear and increase the life but the key is really the operator.
