Idk if if this is an issue or not, but on some lawns/many lawns, i get these 2 lines down the center of my stripes.
Mower is a 2010 Super Z (xr7 of course)
also have a 2006 Super Z (also xr7) that i have seen it do this also.
blades are the fusion oem ome ones. fresh and sharp.
there seems to be no uncut grass on the lines, just a visual thing.
Whats the deal? What causes this?
