My lot is half an acre and the lawn is back yard and front yard split by the driveway. Mowing takes me about an hour going round and round. If I was going to do fancy stuff like diagonals and parallel stripes, I'd have to allow at least 50% more time, if not double. Going clockwise without a mulching plate just piles the clippings towards the centre, making it hard on the mower and leaving a mess. So, the way I would do it is once around the fence line clockwise, then continue counterclockwise, blowing the clippings to the outside. The next time, I'd put on the mulching plate and do it all clockwise. Then, last year, when I thought I'd broken the axle on my 34" JD RER, I bought a used Honda 30" RER. Well, it turned out I could fix the JD (just a broken axle flange weld), so now I have a different system. I mow alternately with the Honda counterclockwise and with the JD clockwise with a mulching plate. The 4" difference in cutting width ensures I'm not driving in te same tire tracks every time.
