Wire brush for strimmer

Formseal weed brushes are designed for brushcutters with a 25.4 mm (1″) mounting and can also be adapted for machines using a 20 mm mounting with the supplied adapter ring.

However, mounting diameter alone does not guarantee compatibility. You should also check:

• The fixing and flange system

• Maximum permitted accessory diameter

• Maximum operating speed

• Required guards or mounting components

• The brushcutter manufacturer’s instructions

Always confirm that your brushcutter is suitable for this type of attachment before fitting a weed brush.

Formseal weed brushes may be suitable for selected models from several manufacturers, including:

• STIHL

• Husqvarna

• Makita

• Honda

• STIGA

• ECHO

• Shindaiwa

Selected STIHL and Husqvarna brushcutters use 20 mm or 25.4 mm (1″) mounting systems, while some professional Makita brushcutters feature a 25.4 mm mounting.

However, specifications vary between models. Compatibility must always be checked for the individual machine, including its mounting system, permitted accessories and operating requirements.

Check the technical specifications or owner’s manual for your machine.

Manufacturers may describe this specification using terms such as:

• Bore size

• Arbor size

• Mounting diameter

• Mounting hole

• Fitment

• 20 mm

• 25.4 mm

• 1″

This depends mainly on the type of weed growth and the surface.

Twisted steel wire brushes are designed for tougher and more established weed growth where a more aggressive cleaning action is required. They are suitable for demanding applications on robust surfaces such as concrete and stone.

Available in 150 mm and 200 mm diameters.

Synthetic PP brushes are better suited to lighter weed growth and surfaces such as decorative paving where a less aggressive brushing action is preferred.

Available in 170 mm and 200 mm diameters.

Yes. The synthetic versions use PP filament instead of steel wire and are classified as spark-free within the Formseal weed brush range.

This makes them an alternative for applications where sparks caused by contact between steel wire and the surface are undesirable.

The Formseal range currently consists of four configurations:

• Twisted steel wire: 150 mm diameter

• Twisted steel wire: 200 mm diameter

• Synthetic PP: 170 mm diameter

• Synthetic PP: 200 mm diameter

All four configurations have a 25.4 mm (1″) mounting hole, with a supplied adapter ring for 20 mm mounting systems.

The most suitable diameter depends on the brushcutter and the application.

A strimmer weed brush is designed for mechanical weed removal from hard surfaces and difficult-to-reach areas.

Typical applications include:

• Kerbs

• Pavement edges

• Block paving

• Decorative paving

• Paths

• Car parks

• Areas around posts and street furniture

A brushcutter makes it easier to reach edges and obstacles that may be inaccessible to larger weed-removal machines.

The two attachments are intended for different jobs.

Strimmer line is mainly used for cutting grass and softer vegetation.

A weed brush provides a mechanical brushing action designed to remove weeds and vegetation from hard surfaces such as paving, kerbs and car parks.

Consider three main factors:

1. Your brushcutter
Check the mounting size and machine specifications.

2. The type of weed growth
Heavy or established weeds generally require a more aggressive brush.

3. The surface
Decorative or more sensitive paving may benefit from a synthetic brush.

As a simple starting point:

• Heavy weeds: Twisted steel wire

• Lighter weeds / decorative paving: Synthetic PP

If you are still unsure, contact Formseal with your brushcutter brand and model and details of the application.
