As a long standing grounds person i can offer you this in advice in reply.
The stripped effect seen on lawns can be obtained in various ways, but please keep this in mind , just rolling or dragging a brush in alternative directions will give you the stripped effect as it flattens the grass blades down in a given direction of travel and the the effect of daylight on the blades results in the stripped pattern.
The down side is the grass will soon return itself to an upright position, maybe within a few hours at worse case , but you will probably get a day or so if lucky, if the weather is warm and sunny its going to to stand up again quickly.
If however you use a good cylinder mower with a heavy rear roller on a regular basis the grass blades will start to get used to being rolled and cut in that direction and the stripes will last for some time .
rotary mowers will work but due to the nature of the cutting device the grass blades after being cut are allmost twisted around under the cutting deck in a circular motion before being either sucked out the back or side or just left behind the deck as guttings, you will not get any stripes this way unless you have a roller of some description behind the cutting device.
A reel mower or cylinder mower has the advantage here as the cutting cylinder works in the same way as a pair of scissors by cutting the grass blades between to blades and then the roller follows and leaves you the stripe, but the cutting action of this method combined with the rolling does make for a better lawn cut and of course stripe effect.
I cut a lot of grass here (3-4 acres of formal lawns) every 4 dyas with a prof cylinder mower and it is very , very heavy , it leaves an outstanding cut and finish with stripes that last well into the next mowing session.
the downside is that to keep the grass looking at its best the direction of travel/cut has to be changed regulary to prevent wear on at the turning points etc and to keep the blades of grass in good shape, cutting in the same direction for to long will give you nice stripes that last, but the grass needs to be cut from differing directions to ensure a continued quality of cut .
At the end of the day the stripe effect is a just that, an effect , its a by product of lawn mowing with a roller or just rolling/brushing.
hope that helps a bit, just my input from 35 years experiance.
