I'm new to the industry and I was wondering how I can stripe my lawns as well as my competition. All I mow with is two walk behind Honda HRX's and a John Deere walk behind when I have to. The lawns I mow look pretty good for one day then the stripes fade away...my competitors stripes last for a week or more, I assume I need to buy some kind of attachable roller for my mowers...Does anyone out there know what I need to get to make those perfect stripes??? please help me!!!
