Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the exact coil geometry and spring rate required for proper H arm return travel on Multiquip ride-on trowels — not a generic substitute.
- Drop-In Replacement for the Large Boss Position — Engineered specifically for the large boss mounting point on the H arm assembly, seating correctly without modification to the arm or pivot hardware.
- Broad Ride-On Trowel Compatibility — Fits HHNG5, HHXDF4-DF5, HTN28K, HTN27K, and HTNS5S-2 series mechanical ride-on trowels, covering a wide range of Whiteman and International platforms.
- Consistent Blade Pitch Response — A correctly tensioned return spring keeps the H arm snapping back to its neutral position predictably, maintaining even blade pitch control across all four rotor assemblies.
- Sourced Direct from Multiquip — Sold as part number 11594 through DHS Equipment, an authorized Multiquip parts distributor, so you receive an authentic component backed by the OEM supply chain.
The H arm return spring is responsible for pulling the H arm back to its neutral position after the operator adjusts blade pitch on a ride-on power trowel. Without proper spring tension, the arm may return sluggishly or inconsistently, causing uneven blade angles across the rotor and reducing the quality of the concrete finish. A worn or broken spring can also create unpredictable handling characteristics, making timely replacement an important part of keeping the trowel performing as intended.
