Striped lawns are a trick of the light
How to mow lawn stripes
To get the perfect striped lawn on a ride-on mower, you take lessons from ice hockey. The machines used to smooth ice use a set pattern that translates well to lawns. 1 Mow around the outside edge of the lawn, creating a ‘ frame’. 2 Mow down the middle of the area, then turn to either of the outside edges and mow back down that side. 3 Go back to the middle and mow beside your first pass on the opposite side of the outside edge you mowed in Step 2. 4 Repeat the pattern until you finish.
This should leave your lawn looking half dark-green, half light-green. In the lighterlooking stripe, the grass is bending away from you; where it’s darker, it has been bent towards you.
The effect won’t be strong, unless you use a roller behind your mower to ‘bend’ the cut grass. You can buy these, or some keen people make their own (search Google or Youtube for examples). On sports fields, the patterns in grass are far more effective, achieved using large reel mowers and heavy rollers.
