Overview:
The Husqvarna Dense Grass Trimmer Blade 275 4T 20MM (manufacturer part number 578444801) is a genuine steel cutting blade for clearing dense grass and coarse vegetation with a clean finish. Built from durable, hardened steel with a protective painted finish, it is designed to stand up to regular professional and domestic use. The 4-tooth profile delivers strong bite and steady progress through thick growth while maintaining control around edges and obstacles.
