Description
The turf on the football pitch of the Germany Bundesliga presents very clear and unified stripes: dark green and light green staggers line to line on the turf. They are actually manufactured by the mower. Mowing worker drives the mower,rolling the turf from one end of the pitch to the other along the direction that parallel to the pitch midline, then at the end, it returns back to trim and roll the adjacent turf along the opposite direction. As the grass dumps in different directions, their reflection of light is different as well,thus the light and dark interphase stripes appears,which are hard to see at close range. - from Amzon
