A lawn roller gives you a neat and even lawn. A lawn roller is any heavy cylinder with handles that is rolled over grass to even it out. Two basic materials used in their making are metal or concrete. The most common lawn rollers are made out of a metal cylinder and filled with water. The cylinder can be drained for easy transport then filled, whenever rolling needs to be done. It is also common to fill lawn rollers with sand - however this will make it even heavier. Lawn rollers are heavy and so they can be challenging to use, however tow-behind lawn rollers can be attached to your tractor. Lawn rollers are necessary if you have planted a new lawn or recently re-sodded. Commercially made lawn rollers are available for approximately $150 online.
