This riding lawn mower muffler is a replacement part for mowers that have a bad or damaged muffler. The muffler reduces the amount of exhaust noise that comes from the mower. It is also needed to prevent exhaust sparks from igniting dry leaves, grass, or other debris on the ground. Without a muffler, it could also allow cool air to get into the exhaust valve, which could cause the engine to lose compression. This could mean needing a valve replacement. The muffler on a riding mower can become damaged and have other issues after a couple of seasons. A buildup of soot in the muffler can cause it to be less effective. Additionally, the muffler could develop small holes or cracks that will reduce or eliminate its effectiveness entirely. When the muffler is no longer working properly, or if it has been several seasons, it is a good idea for owners to replace the muffler. This is a genuine OEM part sourced from the manufacturer. It can be used with riding mowers from a range of manufacturers including Ryobi, Husqvarna, Poulan, Craftsman, Jonsered, and Ariens.
