For Deck Size: 52 inches/36 inchesBlade Type: Mulching Blade Features:?The lawn tractor blade fits 52 inch deck discharge mower accurately and are notably more durable than older ones, resulting in a great-looking yard and an even, finely chopped cut. ?Ease of installation: People are able to perform the blade replacement independently.
