Description
The Husqvarna Bump Knob 577 04 93 01 is a genuine replacement part designed for Husqvarna trimmer heads with a semi-automatic line feed system. This essential component helps restore smooth line advancement, allowing your grass trimmer or brushcutter to perform at its best.
Over time, bump knobs can wear down from regular contact with hard surfaces. Replacing a damaged or worn knob helps maintain reliable cutting performance and prevents interruptions while working. With this genuine Husqvarna part, you can quickly repair your trimmer head and return to efficient garden maintenance.
The bump knob works with Husqvarna semi-automatic trimmer heads by releasing additional cutting line when the head is tapped against the ground during operation. This simple feed system allows you to extend the line without stopping the machine. As a result, you can keep cutting with fewer interruptions.
Manufactured to Husqvarna’s original specifications, this replacement knob delivers reliable fitment and dependable performance. It is compatible with selected Husqvarna grass trimmers and brushcutters, including models fitted with compatible T25 B trimmer heads. Always check your machine model and trimmer head before ordering to ensure correct compatibility.
Installing a genuine replacement part helps protect your equipment and maintain the performance you expect from Husqvarna products. Instead of replacing an entire trimmer head, you can simply replace the worn bump knob and keep your existing setup working efficiently.
The Husqvarna Bump Knob 577 04 93 01 is a practical spare part for professional landscapers, gardeners, and property owners who rely on dependable outdoor equipment. Keep a replacement on hand to minimise downtime and ensure your trimmer is always ready for the next job.
