I get what you are asking. May be termed different -- Seamless mowing - is how I know it. I will admit that there are times when the turf is 'fluffed up' looks real nice. I have done that in small areas, mostly by cutting forward, then backing up over it, but I still have the tire marks showing. Short of raking out the whole yard or using a blower, neither of which I see as practicle on large turf, I don't know how accomplish this. What many do is 1/2 of yard in 1 direction and next half in other, either by working outside in or starting in middle and working out... but although is isn't striped, it's not seamless either. ... I have received a few comments, not from when the lines were straight, rather from when it was "curvy-swurvy" and "wow, looks great... looks like you had fun" . Oh, well. I mean it looked OK, but I didn't think it was that great, just different for that week.
