First of, I wanted to say that I just picked up the echo pb603. What in the heck would you need more power for? That thing is awesome. Anyway I have a couple questions: What would be the best way to remove the dead grass and break up the ground underneath so I can lay down new topsoil, seed and fert? (It is a 3500sf sqaure of flat land) My 48" scag (newly bought, but used) isnt striping that well, I checked the blades and the were dull as $#%&. They are at my dealer getting sharpened now. Is that the problem? I will be soon purchasing the proslide, and I know that will help with the striping, but will newly sharpened blades make my scag stripe better?
