Multiquip 20720 Operator Platform W/A STX/HTX

The Multiquip 20720 is a genuine OEM Operator Platform W/A STX/HTX designed for Whiteman HTX and STX series ride-on power trowels. This platform assembly is sourced directly from Multiquip, ensuring it meets the exact specifications required for correct fitment and safe operation on these machines. Confirmed compatible models include HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, STX55J6, STX55Y6, and STXD6i. When an operator platform wears, cracks, or becomes structurally compromised, replacing it promptly with part number 20720 keeps the machine in proper working condition.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the structural integrity and dimensional accuracy demanded by ride-on trowel operator platforms.
• Direct-Fit Assembly — Engineered as a complete W/A (weldment assembly) that mounts to the STX and HTX frame without modification, using existing hardware points.
• Broad HTX/STX Compatibility — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, STX55J6, STX55Y6, and STXD6i ride-on trowel models.
• Structural Stability for the Operator Position — A sound platform assembly supports proper operator stance and machine control, directly affecting finishing quality and maneuverability on the slab.
• Operator Safety Compliance — The operator platform is a weight-bearing structural component; using a genuine OEM replacement maintains the load-bearing integrity the machine was rated for at the time of manufacture.

The operator platform on an HTX or STX ride-on trowel is the structural base that supports the operator's standing position during finishing passes. It bears the operator's full weight through every pass and must remain rigid and securely mounted for the machine to respond accurately to operator input. A cracked, bent, or deteriorated platform compromises the operator's footing, reduces machine control, and creates a potential safety hazard on the slab. Replacing a worn platform with the correct OEM assembly restores the machine to its original structural standard and keeps the operator positioned correctly over the trowel's drive system.
