How do they cut the lines of grass on a football pitch??

Question

U know those lines that they use to check if the players are offside or not....how do they cut them so that they are different colors??

Answer 1

They're cut by simply running the mower in one particular direction over the course of several cuts when the grass is damp.

And the lines are not used to judge offside - not all football pitches have straight cuts, some are circular and some are diamond / jacquard patterned.  These take more complicated cutting regimes, but it's all in the grass care.

Answer 2

Yes pricely it is use to check offside.

They cut the grass in such a way that between two lines there is alternatively dark green and light green.

It use to check offside, it is in such a way that the places which are more green at that place the grass is cut less so the grass is more greener than the other.
