How to Change the Blade on Kohler Courage XT7 Mower

Walk-behind lawnmowers, with engine power, provide easy operation when cutting a large grassy area. Many lawnmower manufacturers use different engine makers to enhance the overall power of the product. Kohler offers an engine, called the Courage XT7, that is installed on a number of different mowers. The Kohler engine controls the mower's blade motion during operation. However, the mower's blade will become dull over time, requiring a replacement blade assembly.
