How to Replace Mower Deck Blades on Model # 917273770
The Craftsman 917.273770 is a lawn tractor designed for residential use. The mower has a 22-horsepower motor, an electric-start ignition and a six-speed transaxle. To cut grass, the mower has a single blade, located below the mower deck. After regular usage, the blade will begin to wear. Eventually you'll need to either replace it with a new blade or sharpen it. Replacing the blade is a relatively simple task that a competent do-it-yourselfer can accomplish without taking the tractor in for service. Does this Spark an idea?
