Striping kits: (This is long but worth it... please read!) While striping kits make the grass look awesome, you may not know that you are doing more harm to the yard then good (even though this may be ok to please the customer). I used to use striping kits until I took a class this past summer and realized the damage that they can do to grass. We, lawn care professionals are hired by our customers to take care of their yard in a professional manner, and to also keep the grass looking as healthy as possible. Our lawnmowers that we spend thousands of dollars to buy shouldnt need another attachment added to them to make the yard look better. The way that our lawnmowers are designed is they are supposed to pull the grass up so it stands straight and then cut it. By pulling the grass up straight, this allows the grass to get an even cut. When we use striping kits, it then tries to force the grass to lie back down, so it will create a striping pattern when looking at it. One may think: whats wrong with that, but in fact there is a lot wrong with it when we are dragging something back over the grass other then the plastic piece that is made on the lawnmower to create its own stripe. Here is the way that my teacher told me if we were to take a nail and drag it across a green leaf on a tree, and then look at it a couple of days later it would be black where we dragged the nail across it. This is very similar to what we are doing to the grass when we use chains or these other types of striping kits. We are dragging things over the lawn putting little scratches on the blades of grass that we cannot even see until it is too late, and then we dont even realize what is causing the problem. Cutting the blades of grass can increase the chance of disease in the grass, can increase the amount of nutrients it needs to be healthy, amount of water needed and many more things. If you take two yards in the heat of summer under the same conditions (same amount of water, fertilizer, sun, etc..) I would be willing to bet that the yard without the professional using a striping kit will withstand brown patch etc. easier then the yard where the professional lawn company using the striping kits. I think that these striping kits are the new lawn fad and are also just another way for exmark, toro, scag, etc.. to make more money. I just wanted to share what I learned and hear your opinions and whether it makes since or not!! Please dont come screaming at me if you disagree, just post why. I am also not telling everyone that they should go take off their striping kits because if customers like stripes on their yard and are happy then why change (customers dont realize what I said anyway). If I need to explain anymore please let me know!
