Husqvarna Brush Cutter Head Guide: 5 Expert Tips for Efficiency

This isn’t just about slapping on any old head and hoping for the best. It’s about understanding the nuances of different head types, line selection, and operating techniques to achieve optimal performance.

1. Understanding Brush Cutter Head Types

The first step to efficiency is choosing the right brush cutter head for the job. There’s no one-size-fits-all solution here. The type of vegetation you’re tackling, the size of your property, and your personal preferences all play a role.

String Trimmer Heads: These are the most common type, ideal for light to medium-duty work like trimming grass and weeds around obstacles. They use nylon string as the cutting element, which is relatively inexpensive and easy to replace.
Blade Heads: These heads use metal blades, typically with two, three, or four teeth. Blade heads are designed for heavier vegetation like thick brush, small saplings, and tough weeds.
Hybrid Heads: These heads offer a combination of string and blade capabilities. They often feature a metal blade with nylon string attachments for added versatility.
Brush Cutter Head Materials: Most string trimmer heads are made from durable plastic, but blade heads can be constructed from steel or composite materials. Steel blades are stronger and can handle tougher vegetation, while composite blades are lighter and less likely to damage objects if you accidentally hit them.

String Trimmer Heads: The Versatile Workhorse

String trimmer heads are the workhorses of the brush cutting world. They’re versatile, easy to use, and relatively inexpensive. But not all string trimmer heads are created equal. There are two main types: bump-feed and fixed-line.

Bump-Feed Heads: These heads allow you to advance the string by tapping the head on the ground while the brush cutter is running. This is a convenient feature, but bump-feed heads can be prone to jamming if the string becomes tangled inside.

Fixed-Line Heads: These heads require you to manually advance the string by stopping the brush cutter and pulling the string out. This is less convenient than bump-feed, but fixed-line heads are generally more reliable and less prone to jamming.
