FellDen 20" String Trimmer Support Wheel — 20" Height, Fits 0.98–1.34" Shafts, Aluminum U-Bracket for Gas & Electric

The FellDen 20" Adjustable String Trimmer Wheel is a height-adjustable support wheel that attaches to straight-shaft weed wackers and brushcutters to reduce operator fatigue and improve balance.

If you spend time edging driveways, clearing tall grass, or trimming around landscaping, this support wheel converts a hand-held string trimmer into a steadier, more comfortable tool. Designed with a 20-inch overall height and an oxidation-resistant aluminum U-bracket, the unit raises the cutting head to a comfortable working level while sharing some of the tool’s weight. It’s compatible with most straight-shaft trimmers that use a 0.98–1.34 inch (25–34 mm) shaft tube and ships with the wrenches and parts needed for installation.

How does the FellDen wheel make trimming easier?

The support wheel carries part of the trimmer’s weight so you don’t have to support the entire tool with your arms and shoulders. That lowers fatigue and steadies cutting motion for more consistent results.

• 20" overall height positions the head for upright use with less bending.
• Wide 14" aluminum U-bracket reduces tipping and improves stability.
• Reinforced wheels resist wobble and roll smoothly on varied terrain.
• Lightweight construction avoids adding excessive bulk to the tool.

Will this fit my trimmer or brushcutter?

The FellDen support wheel is built to fit the majority of straight-shaft string trimmers, edgers and backpack-style brushcutters that use a 25–34 mm shaft tube. Measure your shaft diameter to confirm fit before purchase.

• Compatible shaft range: 0.98"–1.34" (25–34 mm).
• Works with many gas and electric straight-shaft models on the market.
• Adjustable holder clamps accommodate small variations in tube size.
• Includes hardware to secure the wheel assembly to the shaft.

How easy is installation and adjustment?

FellDen includes the wrenches and fasteners required so most users can install the wheel using basic hand tools. The support-holder height is adjustable to suit taller or shorter operators and can be set quickly for different jobs.

• Supplied installation tools and instructions for faster setup.
• Adjustable height allows ergonomic positioning for each user.
• Simple clamp and bolt system for secure attachment to the shaft.
• Maintenance requires only occasional tightening and wheel inspection.

What durability and stability features should I expect?

The unit uses an oxidation-resistant aluminum U-bracket and reinforced wheels to withstand outdoor conditions and rough ground. The broadened bracket lowers the center of gravity to reduce the chance of the trimmer tipping during use.

• Aluminum U-bracket resists rust and keeps the assembly lightweight.
• 14" bracket width provides a more stable stance while cutting.
• Reinforced wheel hubs minimize wobbling on uneven surfaces.
• Design shares load to reduce wear on shoulder straps and arms.

Who is this for: The FellDen String Trimmer Wheel is aimed at homeowners, landscapers, and professional groundskeepers who use straight-shaft trimmers and want to cut longer with less fatigue. It’s especially useful for taller users who prefer an uprighter working posture, operators who frequently edge long runs or slopes, and anyone wanting steadier, more uniform trimming without upgrading to a larger machine. If your trimmer’s shaft measures between 25 and 34 mm and you want a simple, durable support to improve comfort and control, this attachment is a practical add-on.
