I ordered cruise when I bought my tractor. I took delivery of the tractor and even had to haul it back for the cruise install. But I have to confess to virtually never using it. My field is so bumpy that the cruise was just herky jerky and entirely unnatural the few times that I tried it. I've never really got around to trying it on a flatter surface. I sort of forgot that I even had it. I shudder to admit that I may have wasted a little money on it.
But the cool part of this forum is that here I am, at a computer, three days and three inches of rain into November, chomping at the bit to take it out and play with it. (now that all the serious mowing is done, it's time to play.) I too wonder if the switch lights up?
