I already took some stiff truck bed mat at fastened it to an aluminum angle. Then, bolted it to the drawbar (to go up and down with the deck). It woks a little, but not like a roller. I will try this weekend to lower it a little to really force the grass to lay over and see. I thought it was the height of the cut grass not being long enough, but my neighbor cuts at about 2 inches, and his looks like Wrigley Field. I'm cutting at 3 to 3-1/2 inches to let it fill in, but not alot of striping going on. I am wondering if it is the "field grass" I have.
