FellDen 20" String Trimmer Support Wheel Attachment — Adjustable Height, Fits 0.98–1.34" Shafts, Reinforced Stability

The FellDen 20" String Trimmer Wheel Attachment is a height-adjustable support wheel that reduces fatigue by bearing part of your trimmer’s weight while you edge and clear brush.

This heavy-duty accessory converts a handheld or backpack string trimmer into a steadier, more comfortable tool for long trimming sessions. Built with a widened aluminum U-bracket and reinforced wheels, the support wheel offers improved balance, adjustable height to suit taller operators, and compatibility with most straight-shaft trimmers. Included fasteners and a clear instruction sheet make assembly straightforward, and customer support is available if parts are missing or you need help.

How does the FellDen wheel reduce arm and shoulder strain?

By transferring a portion of the trimmer’s load onto the wheel, you don’t have to carry the entire weight with your hands and shoulders. This lets you work longer with less discomfort and helps steady the cutting head for more consistent results.

• Design shares weight from tool to ground for reduced user fatigue.
• Reinforced wheel construction minimizes wobble during use.
• Lower center of gravity from a 14"-wide bracket reduces tipping risk.

Will this fit my trimmer — what shaft sizes and types are supported?

The FellDen support accommodates straight-shaft trimmers with tube diameters from 25mm (0.98") up to 34mm (1.34"). It’s not recommended for shafts larger than 35mm or for most curved-shaft models, so check your shaft diameter before ordering.

• Compatible range: 25–34 mm shaft tube diameter.
• Made for straight-shaft gas and electric string trimmers and brushcutters.
• Not suitable for shafts exceeding 35mm or many curved shaft designs.

How do you set up and adjust the FellDen trimmer wheel?

Assembly is quick with the included hardware and simple hand tools. Height adjusts up to the 20" overall dimension so taller users can avoid excessive bending; once set, the clamp securely locks the support in place for steady operation.

• Package includes necessary bolts, nuts, and an instruction manual.
• Adjustable support holder height to match operator preference.
• Use provided wrenches to tighten clamps and check all fasteners before use.

What durability and stability features should I expect?

Constructed with an oxidation-resistant aluminum U-bracket and reinforced widened base, this attachment is designed to resist corrosion and remain square under load. The wheel and bracket together aim to provide a stable rolling platform on uneven ground.

• 14" wide U-bracket lowers center of gravity for better balance.
• Reinforced wheels prevent wobbling and improve longevity.
• Maximum recommended load: 50 kg — avoid overloading the assembly.

Who this is for: The FellDen 20" String Trimmer Wheel Attachment is best for homeowners, landscapers, and groundskeepers who use straight-shaft gas or electric trimmers and want to reduce physical strain, improve cutting consistency, and work longer with less fatigue. It’s particularly useful for taller users who need a higher support height than many standard stands offer. If you use a curved-shaft trimmer or your shaft diameter exceeds 35mm, verify compatibility before purchase. For missing parts, defects, or installation questions, FellDen provides a manual, an installation video reference, and responsive customer support within 24 hours.
