No, they only work if the hill is steep enough,. It has built in angle sensors so they will only allow the hydraulic brakes to work when on a very steep hill.
Of course they will work on flat ground, they can be applied at any time in any condition and still stop the mower on a dime. As Ted said, they are no different then auto brakes or even motorcycle brakes.
