The Multiquip 42470-SK Main Frame Kit is a genuine OEM replacement built for the STX6H hydrostatic ride-on power trowel. As a direct OEM component sourced through Multiquip's authorized parts program, 42470-SK meets the original engineering specifications for the STX6H platform — so you can restore structural integrity without guesswork. This kit is the correct choice when the main frame shows damage, fatigue cracking, or wear that compromises machine alignment and blade performance.
Key Features
- Genuine OEM Construction — Manufactured to the same structural tolerances as the original frame, ensuring correct geometry and load distribution specific to the STX6H's hydrostatic drive system.
- Direct-Fit Replacement — Engineered as a complete kit with all frame components matched to original mounting points and fastener patterns on the STX6H.
- STX6H Compatibility — Confirmed fitment for the Whiteman STX6H super-sized hydrostatic ride-on power trowel, eliminating compatibility risk when ordering.
- Structural Performance Restored — A compromised main frame causes blade misalignment and uneven troweling. Replacing with 42470-SK brings blade pitch control and drive response back to operating specification.
- Operator Safety Compliance — The main frame is a load-bearing structural component; using a genuine OEM kit maintains the machine's designed safety margins for operator protection during operation.
The main frame is the structural backbone of the ride-on trowel, anchoring the engine, hydraulic drive components, operator platform, and blade assemblies into a single unified chassis. It carries and distributes the dynamic loads generated during finishing passes, keeping all rotating and hydraulic systems in proper alignment. When the main frame is cracked, bent, or worn, it throws off blade pitch geometry, introduces vibration, and can compromise the hydraulic linkages that control the trowel's drive and steering — making prompt replacement critical to both finish quality and safe machine operation.
