How to Remove the Blades on a Poulan 42-inch Lawn Tractor

The mowing blades on a 42-inch Poulan lawn tractor require frequent inspection, sharpening and replacement. Blades will dull and dent as they hit rocks, pebbles and other hard objects. Replace all bent and heavily damaged blades because they will cut poorly or not at all. Poulan doesn't recommend self-sharpening the blades; however, if you do, make sure the blades are balanced and sharpened evenly. Wear all necessary safety clothing whenever working near the blades of the lawn tractor.
