Husqvarna 577735501 Knob Kit With Screw

When your Husqvarna power trowel control knob strips out mid-pour, this replacement knob kit gets you back to finishing concrete without ordering an entire handle assembly. The kit includes both the control knob and mounting screw for complete installation. Designed as a direct OEM replacement part, it fits Husqvarna walk-behind power trowels and maintains the same grip and control response as the original equipment. Keep one in your tool trailer as a backup since knobs take constant abuse from repetitive adjustments during finishing work. The threaded design ensures secure attachment that won't loosen under vibration. Simple hand-tightening installation means no downtime waiting for a service technician. Built for concrete finishing contractors running Husqvarna trowels who need reliable replacement parts that install quickly between pours.
