Honestly, tried it a number of times, but just don't see the point. My yard is nearly 2 acres in size, but in four sections of different sizes, one of which is 1.25 acres.
Even on the largest piece, where I can mow length wise for a long distance, the cruise doesn't make sense to me. I never mow the same direction twice, and never in a circle, so the distances are not long enough to require cruise.
Even when I tried, the cruise, while not canceling itself always set at a lower speed than what I set it at....hmmmm
