The Multiquip 20409-1 is a genuine OEM Trowel Blade Arm Left Silver designed for JWN24HTCSL and HSCSL series Whiteman ride-on power trowels. Sourced directly from Multiquip, this part carries the same specifications as the component originally installed at the factory, ensuring a consistent, accurate fit every time. If your machine's blade arm has bent, cracked, or worn to the point of affecting finishing quality, this is the correct replacement to restore full operation. DHS Equipment stocks genuine Multiquip OEM parts so you can get back to work without compromise.
Key Features
- Genuine OEM Construction: — Manufactured to the same dimensional tolerances as the original arm, maintaining proper blade pitch geometry critical to a smooth concrete finish.
- Direct Replacement for JWN Series Trowels: — Engineered specifically for JWN24HTCSL and HSCSL ride-on trowel configurations, mounting to the existing blade spider without modification.
- Left-Side Specific: — This arm is designated for the left blade position; correct side-specific installation is essential to balanced blade loading and uniform finishing passes.
- Silver Finish for Corrosion Resistance: — The silver-finish coating helps the arm resist surface rust and wear in the wet, abrasive environment of fresh concrete finishing work.
- Restores Blade Control and Pitch Accuracy: — A damaged or worn blade arm causes uneven blade angle, resulting in chatter marks, inconsistent surface texture, and operator fatigue; replacing it with 20409-1 brings pitch response back to spec.
The trowel blade arm is the structural link between the spider assembly and each individual finishing blade on a ride-on power trowel. It sets and holds the blade pitch angle, which determines how aggressively the machine works the concrete surface — from floating through to hard troweling. When a blade arm bends or cracks, blade pitch becomes uneven across the rotor, leading to streaking, surface inconsistency, and excess vibration that transfers back through the machine. Replacing a worn arm promptly keeps the rotor balanced and the finishing pass predictable.
