The Multiquip 21428 Step Stha Stx is a genuine OEM replacement step component designed for the STXD6i and STX55Y6 hydrostatic ride-on power trowel series. Sourced directly from Multiquip, part 21428 meets the same specifications as the component installed at the factory, ensuring a direct, trouble-free installation. This part is confirmed to fit STXD6i and STX55Y6 machines, making it the correct choice when servicing or restoring access hardware on these hydrostatic trowels.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, so the step seats and secures exactly as intended on the machine frame.
- Direct Bolt-On Replacement — Designed to replace the original step on STXD6i and STX55Y6 trowels without cutting, drilling, or fabrication.
- Confirmed Fitment — Verified for STXD6i and STX55Y6 hydrostatic ride-on power trowels; always cross-reference part number 21428 before ordering.
- Restored Operator Access — A secure, intact step is essential for safely mounting and dismounting the machine during operation cycles on the job.
- Operator Safety Relevance — A damaged or missing step creates a slip-and-fall hazard; replacing it promptly with a correct OEM part restores safe ingress and egress to the operator platform.
The step on a ride-on power trowel provides the operator with a safe, stable point of contact when mounting and dismounting the machine. On large hydrostatic trowels like the STXD6i and STX55Y6, operators frequently climb on and off the platform during finishing work, placing consistent stress on the step and its mounting points. When a step becomes bent, cracked, or detached, it creates a fall hazard and should be replaced immediately to maintain safe working conditions.
