SENIX 22 Inch Walk Behind String Trimmer vs WOODS OEM 57189KT (57189-2 Blade Set) 26
Quick Verdict
These two products serve fundamentally different purposes, making a direct head-to-head comparison unusual. The SENIX 22 Inch Walk Behind String Trimmer is a complete, self-propelled machine designed for trimming grass and light weeds along fences, walls, and around obstacles. The WOODS OEM 57189KT is a replacement blade set for a Brushbull series rotary cutter, intended for heavy-duty brush and vegetation management with a tractor or zero-turn mower.
If you need a dedicated, easy-to-use trimmer for lawn maintenance, the SENIX is the clear choice. If you already own a WOODS Brushbull cutter and need replacement blades, the WOODS set is your only option. They are not competitors.

Where SENIX Wins
The SENIX wins for the homeowner who wants a complete, ready-to-use machine. It eliminates the need for a separate trimmer head and line replacement—just add fuel and start. Its 22-inch cutting width is generous for a walk-behind trimmer, covering ground faster than a handheld unit. The 160cc 4-cycle engine provides reliable power without mixing oil and gas, and the walk-behind design reduces fatigue compared to carrying a trimmer for extended periods. It also has a large user base with hundreds of reviews, giving you a broad sense of real-world performance. For residential lawn care, it is a purpose-built solution.
Where WOODS Wins
The WOODS blade set wins for anyone who already owns a WOODS Brushbull series rotary cutter (specifically models using a 26.5-inch blade set). It is an OEM replacement part, ensuring a perfect fit and original-equipment quality. The higher user rating (4.6/5) reflects satisfaction among buyers who know exactly what they need. For heavy-duty brush cutting—thick saplings, briars, and overgrown fields—a rotary cutter with sharp blades is far more capable than any string trimmer. The WOODS set is also significantly cheaper than buying a whole new cutter deck. If you maintain large acreage with a tractor, this is a necessary, cost-effective purchase.
